The correct answer is D. All of the above are correct. Answer A is not correct by itself because while the pH can be an indication that the coolant needs to be replaced, the coolant also needs to be checked for the other factors. Answer B is not correct because while the freezing and boiling points are important, the coolant must also be checked for the other aspects to determine the true condition of the coolant. Answer C is not correct because even though the specific gravity is often used as a measure of the freezing and boiling point (percentage of ethylene glycol in the coolant), the coolant must also be checked for the other aspects to determine the true condition of the coolant.

The correct answer is D. Antifreeze can be colored green, orange or red and therefore the best answer is that any of the above colors could be coolant leaking. Answers A, B, and C are not correct because the color of the coolant can be any of the colors listed.

The correct answer is B. To help prevent air from being trapped in the cooling system, the bleeder valve, located at the highest point in the cooling system should be opened to allow the air to escape. Answer A is not correct because, while using the proper antifreeze is important, it will NOT prevent air from trapped in the system. Answer C is not correct because even though some vehicle manufacturers such as Honda and Toyota specify that premixed coolant be used, it will NOT prevent air from trapped in the system. Answer D is not correct because wearing protective gloves will not prevent air from getting trapped in the cooling system.

The correct answer is C. The components of the valve train operate at half engine speed. These components include the camshaft, valve lifters, pushrods and rocker arms, if equipped. Answer A (rod bearings) is not correct because rod bearings ride on the crankshaft and therefore rotate at engine speed and not half engine speed so they would unlikely be a cause of a ticking sound heard at half engine speed. Answer B (main bearings) is not correct because main bearings are on the crankshaft and therefore rotate at engine speed and not half engine speed so they would unlikely be a cause of a ticking sound heard at half engine speed. Answer D (water pump) is not correct because it rotates at about the same speed as the engine through an accessory drive belt and not half engine speed so they would unlikely be a cause of a ticking sound heard at half engine speed.

The correct answer is B. The w indicates that the viscosity (5) was tested at a lower temperature, usually about 0 degrees instead of when hot such as was done for the last number (30). Answers A (weight), C (with) and D (any of the above) are not correct because only answer B (winter) is correct.

The correct answer is D. Both B and C are correct. Answer B is correct because the concern has to be verified in order for the repair to be verified. Answer C is also correct because the concern has to be verified to ensure that the customer concern is a true problem and not normal operation. Answer A is not correct because while there may be a charge to the customer for diagnosis, there is seldom a charge to the customers for verifying the customer concern.

The correct answer is A. Any fluid leak will tend to fall downward due to gravity and to flows toward the rear of the vehicle during driving due to airflow. Answer B is not correct because while fluids will be seen dripping from the lowest place, the location of the leak is usually higher. Answer C is not correct because the fluid leak will be wet (not dry). Answer D is not correct because the source of the leak is the highest place (not the lowest) place where the fluid is seen.

The correct answer is C. A worn rod bearing will usually produce a knocking sound when the engine is first started and then goes away when engine oil finally fills the gap and the sound then goes away. Answer A (worn main bearings) is not correct because a worn main bearing will usually make a knocking sound when the engine is under a heavy load and not heard at start. Answer B (leak intake manifold) is not likely to cause to a knocking sound although it could the root cause of coolant leaking into a cylinder overnight and then causing some sounds and maybe some exhaust smoke or steam, but is unlikely to be the cause of an engine knock at engine start. Answer D (cracked piston) is not correct because a cracked piston is unlikely to make knocking sound but if it did, it would not go away after the engine has run.

The correct answer is A. All fasteners should be tightened to the vehicle manufacturer’s specifications and this may be expressed in inch-pounds (not foot-pounds). Answer B is not correct because using RTV on a rubber gasket will cause the gasket to move out of location which will likely cause a leak. Answer C is not correct because old engine covers can be reused if they are not damaged and the gasket surface is unharmed. Answer D is not correct because just answer A is correct.

The correct answer is D. All of the above are correct. Answer A is correct because the oil life monitor should be reset so it will work as designed to warn the driver when the oil needs to be changed and to clear the message. Answer B is also correct because the Technician should always verify that no leaks are present after an oil change and before releasing the vehicle back to the owner. Answer C is also correct because the oil level should always be checked to make sure that is properly filled and not over-filled nor under-filled.

The correct answer is B. The pressure cap should be tested as part of any cooling system inspection to make sure that it is able to hold the specified pressure. Answer A is not correct because the cooling system should be pressurized to no higher than the pressure rating of the pressure cap and this is usually less than 17 PSI. Answer C is not correct because the freeze protection should be -34 degrees (not just zero degrees). Answer D is not correct because answers A, and c are not correct.

The correct answer is D. Both A and B are correct. Answer A is correct because the fluid should be added when the warning message appears on the dash. Answer B is also correct because most vehicle manufacturers size the DEF reservoir so that it should only need to be filled at the schedule oil change intervals thereby making it more convenient for the vehicle owner. Answer C is not correct because the Diesel Exhaust fluid is consumed by the emission-control system when the engine is running and needs to be filled on a regular basis.

The correct answer is A. The “jiggle” valve is an opening in the thermostat that allows air to escape upward to the radiator where it can then leave the cooling system and not get trapped as an air pocket. This valve needs to be placed in the up position because air is lighter than the coolant and will tend to move upward in the system. Answers B, C, and D are not correct because they do not state that the jiggle valve needs to be at the 12 o’clock position to allow any trapped air to escape.

The correct answer is B. The air dam used in the front of the vehicle is used to direct the airflow up through the radiator and not underneath the vehicle at highway speeds. Therefore, if the air dam is missing, a lack of cooling at highway speeds is the most likely cause. Answer A is not correct because during city-type driving the cooling fan is responsible for ensuing sufficient airflow through the radiator and the ram air effect is not a big factor at lower vehicle speeds. Answer C is not correct because it serves a function and while it does add a sporty look to many vehicles, this is not the purpose or function of the front air dam. Answer D is not correct because the air dam directs the air through the radiator instead of traveling underneath the vehicle and while it may reduce wind noise at highway speed, that is not the purpose and function of the air dam.

The correct answer is D. All of the above warnings light are turned on as a bulb check when the ignition is first treed on. Answers A, B, and C are not correct because all of the mentioned warning lights come on when the ignition is tureen on as a bulb check.

The correct answer is B. A clogged air filter will restrict the airflow into the engine and this will reduce engine power. It is similar to having a throttle plate that does not open all the way. The engine will operate normally at idle and at low speeds but will not have normal power. Answer A is not correct because a restricted air filter does not affect the air/fuel ratio in a fuel injected engine unlike what can occur if the engine was equipped with a carburetor. Answer C is not correct because the air/fuel ratio is not affected and therefore the exhaust emissions, including NOx emissions, would not change. Answer D is not correct because only b is correct.

The correct answer is A. A clogged or defective PCV valve will affect the idle because 20% or more of the air entering the engine at idle flows through the PCV valve. Therefore, any fault with the valve that affects airflow will affect engine operation but mostly at idle speed only. Answer B is not correct because a defective PCV valve will unlikely recue engine power because the amount of air entering the engine above idle speed is very small compared to the amount of air entering the engine through the throttle plate. Answer C is not correct because an engine misfire is unlikely to be caused by a defective PCV because the amount of air entering the engine above idle speed is very small compared to the amount of air entering the engine through the throttle plate would not cause a misfire. Answer D is not correct because a fault with the PCV valve does not affect the evaporative emission control system which is part of the fuel system and not part of the engine vacuum.

The correct answer is B. The number zero after the P (passenger car) indicates that the code is the same for all vehicles (generic). If the number had been a one or a two, then this would indicate that it is a vehicle specific DTC. Answer A is not correct the first number is a zero which indicates that the code is the same for all vehicle regardless of make or model. Answer C is not correct because OBDII trouble codes cannot be retrieved using a jumper wire and counting flashes which as commonly done with some older vehicle s before 1996. Answer D is not correct the first number is a zero which indicates that the code is the same for all vehicles regardless of make or model.

The correct answer is B. If the DEF level becomes low, a warning message is displayed. If this message is ignored and DEF is not added, then eventually the engine power will be reduced. Answer A is not correct because eventually the engine will not start if the DEF is not filled. Answer C is not correct because while the engine power will be reduced if the warning message is ignored, the cranking of the engine is not affected. Answer D is not correct because the glow plugs are not affected by the DEF messages.

The correct answer is D. All the above are correct. Answer A is correct because stored diagnostic trouble codes should be retrieved as many do not cause the “Check Engine” light to come on so the driver would never know there was a fault detected. Answers B and C are also correct because the level, color and condition of the fluid are all important when diagnosing automatic transmission/transaxles concerns.

The correct answer is A. Automatic transmission cooling lines are metal lines that run between the transmission or transaxle to the radiator where the ATF is cooled through a separate passage inside the radiator. Answer B is not correct because the lines do not extend rearward to the rear axle. Answer C is not correct because the cooler itself is located inside the radiator on most vehicles. Answer D is not correct because the cooling lines travel to the radiator and not to the heating, ventilation and air conditioning (HVAC) module.

The correct answer is A. A scan tool is used to monitor the temperature of the automatic transmission fluid. Vehicle manufacturers specify that the fluid level be at a certain level at a specified temperature and the scan tool can monitor the temperature from reading provided by the fluid temperature sensor. Answer B is not correct because while it is important to check for stored diagnostic trouble codes (DTCs), the purpose of using a scan tool to check fluid level is to use the data from the fluid temperature sensor to detect the temperature of the ATF. Answer C is not correct because the operation of the solenoids is not important information to know to check the level of the transmission fluid. Answer D is not correct because a scan tool is not capable of determining the fluid capacity of the transmission or transaxle.

The correct answer is D. All of the above are correct. Answer A is correct because vehicle manufacturers specify where the filter is located as well as the recommended service procedure. Answer B is correct because vehicle manufacturers specify where the filter is located and what type of filter to use. Answer C is correct because vehicle manufacturers specify where the filter is located as well as the specify service procedure to follow to replace it.

The correct answer is D. The correct answer included numbers that start with a seven (7). Answer A is not correct because a DTC that is 3xxx means that it includes vehicle related DTCs. Answer B is not correct because a DTC that is 5xxx means that it includes vehicle speed related DTCs. Answer C is not correct because a DTC that is 6xxx means that it includes computer output-related DTCs.

The correct answer is A. The correct answer states that the specified fluid be used. It also includes that a known brand name be used to help avoid some that may not meet specifications. Answer B is not correct because engine oil is not used in automatic transmissions/transaxles. Answer C is not correct because a non-friction modified ATF would result in hash (not smooth) shifts and is not recommended except for use in older band-type units. Answer D is not correct because even though highly-friction modified ATF is used in many automatic transmissions/transaxles, it is not used in all of theme.

The correct answer is D. The correct answer includes either a drain plug, used in some units or removes the pan, used in most units. Answer A is not correct because while some units do use a drain plug, other need to have the pan removed. Answer B is not correct because while most units do require that the pan be removed, many units use a drain plug. Answer C is not correct because, while all units use a vent, it is not removed to service the unit.

The correct answer is A. The correct answer includes either DOT 3 brake fluid or clutch fluid which is similar to brake fluid and are the specified fluid to use in hydraulic clutches. Answer B is not correct because DOT 5 brake fluid is not specified for use in hydraulic clutches. Answer C is not correct because solvent is not specified for use in hydraulic clutches Answer D is not correct because brake clean is not specified for use in hydraulic clutches.

The correct answer is D. The correct answer includes ATF, engine oil or gear lube and is the specified fluids to use in manual transmissions/transaxles. Answer A is not correct because while ATF is the specified fluid to use in many units, it is not to be used in all manual transmissions/transaxles. Answer B is not correct because while engine oil is often specified in some manual transmission/transaxles, it is not specified for use in all units. Answer C is not correct while gear lube may be specified for use in some older manual transmissions/transaxles, it is not specified to be used in all units.

The correct answer is B. The correct answer is that the boots (bellows) are made from rubber or plastic. Answer A is not correct because while CV joints themselves are made from steel, the boots (bellows) are not made from steel. Answer C is not correct because CV joint boots are not made from aluminum. Answer D is not correct because CV joint boots are made from rubber or plastic and not vinyl.

The correct answer is D. The correct answer includes ATF, Engine oil or gear lube and is the specified fluids to use in transfer cases depending on the year, make and model of vehicle. Answer A is not correct because, while engine oil is often specified in some manual transmission/transaxles, it is not specified for use in all units. Answer B is not correct because while ATF is the specified fluid to use in many units, it is not to be used in all transfer cases. Answer C is not correct while gear lube may be specified for use in some older manual transfer cases, it is not specified to be used in all units.

The correct answer is D. All of the above are correct. Answer A is correct because, all tires should be the same brand (size can vary slightly by brand) and size. Answer B is also correct because all ties should have the same inflation pressure which would affect diameter and rolling circumference. Answer C is also correct because the tread depth should, all be the same within 1/16inch.

The correct answer is D. Either A or B are correct. Answer A is correct because powertrain mounts can and are mostly made from reinforced rubber to allow some movement to absorb noise and vibrations from the engine and transmission. Answer B is also correct because many mounts are fluid filled so they can absorb noise and vibration. Answer C is not correct because, while the backing of the mount is often made from steel, the mounts themselves are rubber to so they can absorb noise and vibrations.

The correct answer is C. The correct answer is that rust dust is what is being seen and this means that the needle bearings inside the U-joint are rusting and small particles are being thrown outward. Answer A is not correct because while rust is frequently seen on metal parts where salt is used on the roads, a U-joint has grease inside and this joint should while it can be rusty on the outside, should not be throwing off rust particles due to surface rust. Answer B is not correct because whether the U-joint is cast or forged, this would not be the cause of the rust dust being seen thrown off by the joint. Answer D is not correct because while some U-joints have a grease fitting and should be greased, they are not to be coated with oil because the oil cannot get into the needle bearing.

The correct answer is B. The correct answer is that many joints, especially those that use a center support bearing, need to be properly phased to reduce driveline vibration so it important to mark the position when removing a drive shaft. Answer A is not correct because the position of the U-joint would not affect the balance of the driveshaft even though if it was out-of-phase, it would cause a vibration. Answer C is not correct because while some drive shafts look the same at both ends, most have a unique U-joint which means that the drive shaft cannot be installed backward. Answer D is not correct because while some U-joints have a grease fitting and should be greased, they are not to be coated in oil because there is no need to keep the easterners in the same position as this would not affect the balance at all.

The correct answer is A. The vehicle may suffer from a vibration or driveline bind if the tires are not the same diameter causing them to rotate at different speeds. Answer B is not correct because the oil level is not affected enough by different tire size to affect the reading. Answer C is not correct because the speedometer readings would not be affecting enough by different tire size to affect the speed. Answer D is not correct because only answer A is correct.

The correct answer is A. In this question, the correct answer is what is NOT done and that is the actual removal of the airbag module prior to working on the vehicle. Answer B is not correct because removing the airbag fuse is procedure that is often specified to be used to disable the airbag system. Answer C is not correct because disconnecting the airbag electrical connector is procedure that is often specified to be used to disable the airbag system. Answer D is not correct because disconnecting the battery is procedure that is often specified to be used to disable the airbag system.

The correct answer is D. Any of the above are correct. Answer A is correct because the specified power steering fluid is often written on the cap. Answer B is not correct because the specified fluid is included in the owner’s manual. Answer C is correct because the specified fluid to use in the power steering system is also included in service information.

The correct answer is C. This question asks for what is specified except meaning that the length of an accessory drive belt is not checked when inspecting the belt during routine service. Answer A is not correct because cracks are something that should be checked for in a belt during an inspection. Answer B is not correct because wear is something that should be checked for in a belt during an inspection. Answer D is not correct because belt alignment is something that should be checked for during an inspection.

The correct answer is A. Answer A is correct because by raising the front wheels off the ground reduces the forces on the steering and this prevents the trapped air in the fluid from being broken up into small bubbles which are hard to bleed out of the system. Answer B is not correct simply starting the engine and will not likely be able to cause the fluid to move enough through the system without turning the steering wheel. Answer C is not correct because while some vehicle manufactures specify that a vacuum be applied to the reservoir cap opening, this procedure is used in the even that normal bleeding procedures did not work and therefore is not the preferred method as specified by most vehicle manufacturers. Answer D is not correct because a special tool is not specified or needed to bleed air from a power steering system.

The correct answer is D. All of the above are correct. Answer A is correct because the specified torque should be applied to all steering and suspension fasteners. Answer B is correct because the specified procedure is to replace component in pairs even if a part on one side of the vehicle is found to be defective. Answer C is correct because the many steering and suspension parts contain rubber and rubber has a memory. If a part is installed with the front wheels pointing to one side, then the rubber in the part will tend to force the vehicle, to the side where it was installed.

The correct answer is B. The wear indicator is the area around the base of the grease fitting. The base is normally raised below the bottom of the joint and when it wears and becomes flush with the bottom of the joint is the indication that the joint is worn and requires replacement. Answer A is not correct because a line is not used to indicate ball joint wear. Answer C is not correct because it is the steel raised part around the grease fitting that is the wear indicator and not a rubber seal. Answer D is not correct because all wear indicator ball joints uses the same raised area around the grease fitting.

The correct answer is D. All of the above are correct. Answer A is correct because torsion bars can be adjusted to control ride (suspension) height. Answer B is correct because leaf springs do use a center bolt to hold the leaves together. Answer C is correct because springs can and do sag over time and thus can affect the ride (suspension) height.

The correct answer is B. The steering angle sensor usually requires the use of a scan tool to calibrate the steering wheel angle sensor after an alignment has been performed. Answer A is not correct because a scan tool is not required to measure rear toe. Answer C is not correct because the front tie rod ends are used to adjust the steering wheel straight ahead and while a scan tool is then needed to calibrate the steering wheel sensor, it is not used to center the steering wheel. Answer D is not correct because only answer B is correct.

The correct answer is D. Both answers A and C are correct. Answer A is correct because the specified inflation pressure is on a placard on the driver’s door or in the owner’s manual (answer C). Answer B is not correct simply starting the engine and will not likely be able to cause the fluid to move enough through the system without turning the steering wheel. Answer C is not correct because the pressure on the sidewall of the it is the maximum pressure that the tire can handle is not the pressure to use when inflating a tire.

The correct answer is C. Most if not all vehicle manufacturers specify that the relearn procedure start with the left from wheel and move clockwise around the vehicle. Answers A, B, and D are not correct because it is the left front wheel where the relearn process is specified to be used first.

The correct answer is B. Using the modified X method of tire rotation, the drive wheels are moved straight forward or rearward the non-drive wheel are moved forward or rearward and crossed. This means that on a front wheel drive vehicle, the right front will be moved straight back to the right rear position. Answers A, C, and D are not correct because the specified position is at the right rear.

The correct answer is A. The long length of return line is often placed in the airstream so that air flowing past the line will cool the power steering fluid. Answer B is not correct because a length of return line would not have any effect on the air entering the system because the line is closed and not open to the atmosphere. Answer C is not correct because a length of return line would not affect the pump at all and would not reduce noise. Answer D is not correct because the length of the return line may make removing the line harder rather than easier for the Service Technician.

The correct answer is A. Yellow is the color of electrical connectors used in airbag circuits. Answers B, C, and D are not correct because yellow, not orange (high voltage wring), blue (42 volts circuits) or green are used to indicate airbag circuit connectors.

The correct answer is C. Blue or yellow is the color of electrical conduit used in electric power steering systems that use 42 volts. Answers A (red), B (orange) and D (green) are not correct because the color of the electrical conduit is either blue or yellow depending on the make and model of vehicle that uses a 42-volt electric power steering system.

The correct answer is C. Most vehicles equipped with an air suspension have a switch, usually located in the trunk area that should be used to turn of the system if it is to be lifted on a hoist. This keeps the suspension system from letting all of the air out the system. Answer A is not correct because while a scan tool may be able to be used to disable the system, it is not the primary way to do so for routine service operations. Answer B is not correct because while disconnecting the air pump may work, this unit is usually in a location that is difficult to get to and is not designed to be sued to disconnect the system during routine service operations. Answer D is not correct because while disconnecting the air shocks may work, this procedure is not designed to be sued to disconnect the system during routine service operations.

The correct answer is B. An assembly that contains the strut plus the upper mount and spring is called a loaded strut. Answer A is not correct because while the name is similar, the assembly is called a loaded strut and not a complete strut. Answer C is not correct because while the name is similar, the assembly is called a loaded strut and not a strut-spring assembly. Answer D is not correct because while the name is similar, the assembly is called a loaded strut and not a strut-bearing assembly.

The correct answer is A. A shackle is the part of a leaf spring system that allows the spring to become longer when the vehicle hits a bump. Answer B is not correct because a shackle is used with a leaf spring and not a coil spring. Answer C is not correct because a shackle is used with a leaf spring and not a McPherson strut suspension. Answer D is not correct because a shackle is used with a leaf spring and not a multi-link suspension system suspension.

The correct answer is C. Front toe always splits equally when the vehicle moves forward and if the toe is unequal side to the side, the steering wheel angle changes but the toe always splits equally and does not cause a pull. Answer A is not correct because caster unequal caster will cause a pull. Answer B is not correct camber unequal caster will cause a pull. Answer D is not correct because only toe (answer C) is correct.

The correct answer is B. A tire that is overinflated will cause excessive wear to occur in the center of the tire tread. Answer A is not correct because excessive positive camber will cause the tire to wear on the outside of the tread (not in the center). Answer C is not correct because if the tire was underinflated, the outside edges of the tire would wear more. Answer D is not correct because excessive positive caster would not cause excessive inside tire wear but instead would not wear the tires excessively or if driven in city-type conditions may show camber-type wear to both the inside and outside edges of tire.

The correct answer is C. Wheel weights should be made from steel, zinc or a composite to help safe-guard the environment by avoiding the use of lead. Answer A is not correct because clip-on lead weights contain lead and have been outlawed in many states. Answer B is not correct because weights containing lead and have been outlawed in many states. Answer D is not correct because only none-lead weights are to be used (answer C) is correct.

The correct answer is A. A tire repair should only be attempted in the tread area. Answer B is not correct because a tire repair should not be attempted in the sidewall of a tire. Answer C is not correct because a tire repair should never be attempted in the sidewall or near the bead of a tire. Answer D is not correct because a tire repair should only be attempted in the tread area.

The correct answer is D. All of the above are correct. Answer A is correct because if the ride height (suspension height) is not correct, the vehicle could be bottoming out against the jounce (bump) stops when the vehicle hits a bump in the road. Answer B is correct because if the shock absorbers are defective, they may not be able to control the movement of the vehicle when to travels over rises or dips in the road which can cause the suspension to bottom out on the jounce (bump) stops. Answer C is correct because worn or sagging springs can cause the vehicle to have a lower-than-normal ride height and this can cause the vehicle to strike the jounce (bump) stops more often.

The correct answer is B. A tire pressure monitoring system warning light that is one and not flashing, indicates that the system has detected a tire with low inflation pressure. Answer A is not correct because if there is a fault with the system, the warning lamp will flash and not stay on steady. Answer C is not correct because if there was a fault with a sensor, the warning light will be flashing and not on steady. Answer D is not correct because a tire pressure monitoring system warning light that is one and not flashing, indicates that the system has detected a tire with low inflation pressure.

The correct answer is D. All of the above are correct. Answer A is correct because brake lines should be inspected for leaks. Answer B is correct because brake lines should be inspected for brake kinks. Answer C is correct brake lines should be inspected for rust.

The correct answer is D. All of the above are correct. Answer A is correct because the red brake warning (RBW) light will illuminate if there is a fault in the hydraulic system such as loss of pressure in one brake circuit. Answer B is also correct because a fault with the antilock braking system (ABS) will illuminate an amber dash warning light. Answer C is also correct because if the red brake warning light is on, the brakes may not function and therefore the vehicle should not be test driven until the fault has been found and corrected.

The correct answer is A. There are six brake shoe pads on each backing plate, with three for each of the two brake shoes. Answers B, C, and D are not correct because there are six and not 4 (answer B), 2 (answer C) or 8 or more (answer D).

The correct answer is B. The usual torque specified for passenger vehicle lug nuts is 80-100 Lb.-Ft. Answers A (60-70 Lb.-Ft.), C (110-150 Lb.-Ft.) and D (160-180 Lb.-Ft.) are not correct is not correct because they are not within the range of normal torque specifications.

The correct answer is B. On a vehicle equipped with a front disc brakes and rear drum brakes, the rear drum brakes are used as the parking brake. If the rear brakes are properly adjusted, then the parking brake will not be properly adjusted. Therefore vehicle manufacturers specify that the rear brakes be adjusted before the parking brake is adjusted. Often after adjusting the rear brakes, the parking brake works as designed without further adjustment. Answer A is not correct even though the thickness of the front disc brake pads is important, the parking brake does not use the front disc brakes. Answer C is not correct because while the brake fluid level is important, the parking brake adjustment is not affected by the level of the brake fluid. Answer D is not correct because only answer B is correct and the others are not correct.

The correct answer is C. On a vehicle equipped with a floating or sliding caliper-type disc brakes, if the slides or guide pins do not move, then the one pad will wear more than the other (usually the inboard pad). Answer A is not correct because one pad worn more than the other is not normal even though it may be normal for the caliper to be fixed on a fixed-type caliper design. Answer B is not correct because if the caliper piston was stuck in the bore of the caliper, no braking forces would be applied to the brake pads and therefore the pads would not wear at all let alone only on one side. Answer D is not correct because a leaking caliper dust shield may cause the brakes to grab if brake fluid got on the pads, but this could not cause the caliper to be stuck nor cause one brake pad to wear more than the other.

The correct answer is A. The maximum allowable thickness variation of a disc brake rotor is a half of one thousandth of inch or 0.0005. Answers B, C, and D are not correct because they are not a half of a thousandth of an inch.

The correct answer is D. Any of the above is correct which depends on the make, model and year of vehicle. Domestic and Asian brands of vehicles often specify DOT 3 brake fluid whereas, European vehicle manufacturers often specify DOT 4, DOT 4+ or DOT 4 LV (low viscosity). Answer A is correct because most domestic and Asian vehicle manufacturers specify DOT 3 brake fluid for use in their vehicles. Answer B is correct because European vehicle manufacturers often specify DOT 4 brake fluid. Answer C is correct because European vehicle manufacturers often specify DOT 4+ or DOT 4 LV brake fluid be used in their vehicles.

The correct answer is C. Most vehicle manufactures recommend that silicone brake grease be used to lubricate disc brake caliper slides. This type of grease does not react with the rubber used in the O-rings or dust boots. Answer A is not correct because wheel bearing grease is not specified by vehicle manufacturers for use with disc brake caliper slides and it may cause swelling of the rubber used in O-rings and sealing boots. Answer B is not correct because chassis grease is not specified by vehicle manufacturers for use with disc brake caliper slides and it may cause swelling of the rubber used in O-rings and sealing boots. Answer D is not correct because only silicone brake grease is the only lubricant of those listed that is specified for use by vehicle manufacturers on disc brake guide pins.

The correct answer is B. The brake pedal should be depressed several times after replacing disc brake pads to force the pads against the rotors. Answer A is not correct because, while these may be some clearance between the piston and the back of the disc brake pad, the major reason for depressing the brake pedal is to move the pads against the rotor. Answers C and D are not correct because bedding the disc brake pads involves driving the vehicle and this is performed after the brake pedal has been depressed several times to force the pads against the rotors then the vehicle can be driven to begin the bedding in (breaking in) process.

The correct answer is C. Both Technicians are correct. Technician A is correct because to test a vacuum booster, the vacuum needs to be depleted from the booster which normally requires that the brake pedal be depressed several times and then the pedal depressed and held down when the engine is started. If the booster is working as designed, the brake pedal should drop when the engine is started. Technician B is correct because a working vacuum booster should be able to supply 2 or 3 assisted brake applications after the engine has stopped running. Answers A, B, and D are not correct because both Technicians are correct.

The correct answer is B. The most likely cause of a low brake pedal after the installation of a replacement master cylinder is that there is still air trapped inside the master cylinder. This is why vehicle manufactures recommend that the master cylinder be bled on a bench before being installed on the vehicle to make sure that no air is trapped in the passages of the master cylinder. Answer A is not correct because overfilling the master cylinder reservoir will not have any effect on the brake application even though it may cause brake fluid to leak out of the reservoir. Answer C is not correct because, even though misadjusted rear drum brake can cause a lower than normal brake pedal, it is not the most likely cause of a low brake pedal after the installation of a master cylinder. Answer D is not correct because, even though misadjusted brake pedal can cause a lower than normal brake pedal, it is not the most likely cause of a low brake pedal after the installation of a master cylinder.

The correct answer is C. If the caliper was stuck and not able to move on the left front, it would not be able to provide adequate braking force and therefore could be the cause of the vehicle pulling toward the right during braking. Answer A is not correct because air in the lines would cause a low brake pedal and mushy brake pedal but would not likely be the cause of a pulling condition during hard braking. Answer B is not correct because a stick caliper on the right would cause the right front brake to not work correctly and therefore would cause likely cause the vehicle to pull toward the left and not toward the right. Answer D is not correct because while misadjusted rear brakes can cause a low brake pedal, they would not likely be the cause of a pulling toward one side during hard braking.

The correct answer is B. If the red brake warning light is on, this indicates that there is a hydraulic failure in the system or the parking brake is applied. For safety, the cause of the warning light should be determined and corrected before test driving the vehicle. Answer A is not correct because if the amber ABS warning light is on, this indicates a fault with the ABS system and therefore the base brakes should operate normally making it safe to drive the vehicle. Answer C is not correct because the red braking warning light will come on if the brake fluid is below the minimum level, not below the maximum level. Answer D is not correct because only answer B is correct.

The correct answer is C. Parking brake cables that are swollen indicates that the steel cable inside has rusted and expanded. The rust will often prevent the parking brake cable to move and therefore will require to be replaced to restore proper parking brake operation. Answer A is not correct because while misadjusted rear drum brakes can be the cause of the parking brake not holding a vehicle stationary, it would not be the cause of swollen parking brake cable. Answer B is not correct because while a misadjusted parking brake cable could be the cause of a parking brake not holding a vehicle, it would not explain why the parking brake cable is swollen. Answer D is not correct because a parking pawl is part of an automatic transmission/transaxle and not part of a parking braking system.

The correct answer is B. The burnishing in (bedding in or breaking in) of new disc brake pads includes braking moderately from about 50 MPH (80 km/h) until the vehicle speed reaches 20 MPH (32 km/h) and repeat several times. Answer A is not correct because the stops need to be moderately hard to create the heat needed to cure the pads and to produce a layer of friction material to the rotor (called the transfer layer). Answer C is not correct because the stops need to be moderately hard to create the heat needed to cure the pads. Answer D is not correct because performing just one hard braking from highway speed is not the specified method used to burnish in new disc brake pads.

The correct answer is C. Most vehicle manufacturers specify that 0.030 inch be left to allow for wear before the brake drum reaches the discard dimension. Answer A is not correct because the discard dimension is the size of the drum that requires that it be discarded and therefore it should not be used in further service. Answer B is not correct because the maximum ID measurement is the inside diameter that is allowed and therefore it should not be used in further service. Answer D is not correct because only answer C is correct.

The correct answer is C. Both Technicians are correct. Technician A is correct because the red brake warning lamp will come on if the parking brake is applied. Technician B is correct because the red braking warning light will come on if the brake fluid is below the minimum level on most vehicles. Answers A, B, and D are not correct because both Technicians are correct.

The correct answer is A. Brake fluid can absorb moisture directly from the air, so it is important to keep it stored in a sealed container. Answer B is not correct because, even though brake fluid can be stored in a glass container with a screw top lid, keeping it in its original container is best to help avoid contamination. Answer C is not correct because brake fluid needs to be kept in a sealed container and not left open where it could be exposed to the air. Answer D is not correct because, while it can and should be kept in its original container, it does not have to be kept in a refrigerator to keep the temperature of the fluid low.

The correct answer is D. The minimum vacuum needed for the vacuum booster to function correctly is 15 inches of Mercury (in. Hg.) Answers A, B, and C are not correct because most vehicle manufactures specify that the vacuum should be at least 15 in. Hg.

The correct answer is C. Before the brake pedal is applied, there is vacuum on both sides of the internal diaphragm. When the brake pedal is depressed, air enters the rear (passenger compartment side) of the vacuum booster where the pressure then exerts a force against the internal diaphragm. The internal diaphragm is mechanically connected to the input shaft of the master cylinder and as a result, this action reduces the driver’s effort during braking. Answer A is not correct because there is vacuum applied to both sides of the internal diaphragm before the brake pedal is depressed. Answer B is not correct because there is vacuum applied to both sides of the internal diaphragm before the brake pedal is depressed. Answer D is not correct because there is vacuum applied to both sides of the internal diaphragm before the brake pedal is depressed and the air valve is used to allow outside air pressure into the rear chamber of the booster assembly.

The correct answer is B. The longer lining is the lining that does the most work and therefore is the one toward the rear on a dual (Duo) servo drum brake. Answer A is not correct because the longer lining needs to be at the rear (not front) position to be to provide the braking forces needed. Answer C is not correct because the longer lining needs to be at the rear (not front) position to be to provide the braking forces needed. Answer D is not correct because while this may apply to some drum brakes, many drum brakes use front entry and rear entry parking brake cable making this identification not accurate in all cases.

The correct answer is C. Both Technicians are correct. Technician A is correct because to test to test the voltage drop of the positive battery cable, one meter lead needs to be connected to the most positive part of the circuit which is at the positive battery terminal. Then the other meter lead needs to be attached to the battery stud of the starter. Technician B is correct because resistance (voltage drop) is only effective when current flows, so the engine needs to be cranked using the starter to measure the voltage drop of the battery-to-starter cable. Answers A, B, and D are not correct because both Technicians are correct.

The correct answer is D. Either A or B is correct. Answer A is correct because to measure current flow (amperes) in a circuit, the current needs to run through the meter and this means connecting the meter leads in series in the circuit. Answer B is correct because an inductive ammeter uses a sensor built into the clamp that measures the current in the wire by measuring the strength of the magnetic field that surrounds any wire carrying a current. Answer C is not correct because the meter fuse would blow because the meter set on DCA is a low resistance path and current would flow directly from the positive terminal of the battery to the negative terminal of the battery.

The correct answer is A. The last connection should be the on the engine itself or the body away from the battery because a spark often occurs when the last connection is made and this spark could ignite the hydrogen gas given off by the battery when the connection is made. Answers B, C, and D are not correct because the connection is close to the battery and a spark could cause the hydrogen gas to catch fire or cause the battery to explode.

The correct answer is B. It is normal for the air bag warning lamp to flash when the vehicle is started as part of the system self-test. Answer A is not correct because if there was a fault detected in the system, the air bag warning lamp would light after and stay on after the self-test. Answer C is not correct because the flashing and then going out is normal and does not indicate a fault or a need for any service procedures to be performed on the system. Answer D is not correct because the flashing of the air bag warning lamp at engine start and then going out is a normal operation for all vehicles equipped with an air bag system.

The correct answer is A. To prevent a possible spark and personal injury, the battery should be disconnected before performing any service work that requires the main battery cables be disconnected. Answer B is not correct because the negative cable, not the positive cable should be disconnected. If a wrench were to touch the body of the vehicle when removing the positive battery cable from the battery, a spark would likely occur but a spark will not occur if the negative battery was being removed. Answer C is not correct because the starter circuit is not usually protected by a fuse. Answer D is not correct because there is no need to disconnect the air bag especially if the negative battery cable has been removed from the battery.

The correct answer is C. Both Technicians are correct. Technician A is correct because if the alternator drive belt was worn, it could be slipping especially under a heavy electrical load and therefore not charge enough to meet the output specifications. Technician B is correct because if the drive belt tensioner was faulty, then the alternator drive belt could slip and cause the alternator to not be able to produce its rated output. Answers A, B, and D are not correct because both Technicians are correct.

The correct answer is D. Any of the above is correct. Answer A is correct because HID headlights do use high voltage so the wise Service Technician should read, understand and follow all safety instructions that pertain to this type of headlight system. Answer B is correct because the oil on your hands can cause the glass part of the bulb to expand at different rates and often causes the bulb to have a short service life. Answer C is correct because the same trade number bulb should always be used because the trade number determines the size as well as the brightness of the bulb which match the original bulb.

The correct answer is C. Both Technicians are correct. Technician A is correct because the memory can be kept alive by connecting a 9-volt or a 12-volt battery to the lighter plug on my vehicles. Then when the battery is disconnected, the battery connected to the lighter plug will be used to keep the memory functions from being lost. Technician B is correct because there is a chassis ground (terminal #4) and power (terminal #16) available to the data link connector (DLC) on all OBD II vehicles since 1996 which can be used to supply battery power to the vehicle when the vehicles battery is disconnected. Answers A, B, and D are not correct because both Technicians are correct.

The correct answer is A. To measure voltage drop, the meter needs to be set to read DC volts (DCV). Answer B is not correct because to measure voltage drop, the meter should be set to read voltage and not DC amperage. Answer C is not correct because to measure voltage drop, the meter should be set to read voltage and not AC amperage. Answer D is not correct because to measure voltage drop, the meter should be set to read DC voltage and not AC voltage.

The correct answer is B. To measure current flow, the meter needs to be set to read DC amperes (DCA). Answer A is not correct because to measure current, the meter should be set to read amperes and not DC voltage (DCV). Answer C is not correct because to measure current in amperes, the meter should be set to read DC amperes and not AC amperes (ACA). Answer D is not correct because to measure current, the meter should be set to read DC amperes and not AC voltage.

The correct answer is A. The state of charge (SOC) of a battery is usually determined using a hand-held electronic conductance tester or by using a load tester. Answer B is not correct because the resistance of the battery cable cannot be used to determine the SOC of a battery. Answer C is not correct because the voltage being measured with the engine running is the charging system voltage and cannot be used to determine the SOC of a battery. Answer D is not correct because while a scan tool can display the battery voltage, it cannot be used to determine the state-of-charge of the battery.

The correct answer is C. Only windshield washer fluid should be used in a windshield washer system. Typical windshield wiper fluid contains methanol alcohol to protect the fluid from freezing and is also used to help clean the windshield. Answer A is not correct because using distilled water, while it will work when used in areas that do not have freezing weather, it will not help keep the windshield clean and is not recommended for use by vehicle manufacturers. Answer B is not correct because using engine antifreeze will cause smearing of the fluid on the windshield and is not recommended for use by vehicle manufacturers. Answer D is not correct because using clean drinking water , while it will work when used in areas that do not have freezing weather, it will not help keep the windshield clean and is not recommended for use by vehicle manufacturers.

The correct answer is B. Typical charging system voltage usually falls within 13 and 15 volts for most vehicles. Answers A, C, and D are not correct because they do not reflect the usual voltage of a charging system.

The correct answer is A. High amperage draw and slow starter operation is an indication of a defective starter motor or an engine mechanical fault that is causing the engine to crank slower than normal. Answer B is not correct because high resistance in the battery cable while it would result in the starter rotating slower than normal, would also tend to decrease the current draw from the battery and not go high as in this case. Answer C is not correct because, while a defective alternator can cause the battery to have a low state-of-charge and cause a slow cranking problem, it cannot be the cause of a starter requiring higher-than-normal current draw. Answer D is not correct because only answer A is correct.

The correct answer is A. A light bulb filament often has a resistance, measured at room temperature, of about a 0.5 ohm. However, when the filament has current flowing through it, the resistance increases so that measure current flow results in a calculated resistance of about 10 times that of the resistance of a filament measured at room temperature. Answer B is not correct because the bulb filament resistance is normal and does not indicate that it is shorted to another filament or to ground. Answer C is not correct because if the filament were electrical open, the resistance would be infinity and the meter reading would show “OL” or over limit. Answer D is not correct because the filament resistance is normal and does not indicate being grounded which would likely be a much lower resistance reading or zero or almost zero.

The correct answer is A. Vehicle manufacturers specify that the air discharge temperature form an air conditioning system be measured at the center vents. Answers B, C, and D are not correct because the temperature should, be measured at the center vent and not at the driver’s side (answer B), defroster vents (answer C) or the passenger side vent (answer D).

The correct answer is D. All of the above is correct. Answer A is correct because a cabin filter may be located behind the glove compartment inside the vehicle. Answer B is correct because a cabin air filter access may be from under the hood on the passenger side. Answer C is correct because all cabin air filters should be replaced regularly as part of routine vehicle maintenance as specified in service information.

The correct answer is B. The evaporator drain is located under the vehicle on the passenger side so that condensation due to moist air flowing through a cool evaporator will cause the moisture to condense on the evaporator and they it has a place to flow out of the housing to the ground under the vehicle. Answer A is not correct because while the evaporator case is located behind the glove compartment on the passenger side, the drain from the housing is located under the vehicle. Answer C is not correct because the drain is located at the base of the evaporator housing under the vehicle and not near the AC compressor. Answer D is not correct because the drain is always located under the vehicle on the passenger side.

The correct answer is C. When refrigerant leaks, the location can often be seen by looking for an oily spot because as the refrigerant leaves, it takes with it some refrigerant oil. The refrigerant escapes into the atmosphere but the refrigerant oil does not and is seen near the location of the leak. Answers A, B, and D are not correct because the refrigerant escapes into the atmosphere and there is nothing left except for an oily film from the refrigerant oil.

The correct answer is A. While specifications do vary according to vehicle make, model and year, most specifications specify that normal discharge air temperature should be 30 degrees lower than the outside (ambient) air temperature. Answers B, C, and D are not correct because the temperature has to be above 32° F (0°C) to prevent freezing of the moisture in the air.

The correct answer is B. The condenser is located in front of the radiator in the front of the vehicle where it is exposed to the airflow as the vehicle moves forward. Answers A, C, and D are not correct because the condenser is located at the front of the vehicle under the hood and not inside the vehicle (answer A), underneath the vehicle on the passenger side (answer C) or under the dash in the center (answer D)

The correct answer is D. All of the above is correct. Answer A is correct because the engine needs to be running in most cases for the blend and mode doors to function. Answer B is correct because the controls should be switched on and off to check that the location of the discharge airflow changes Answer C is correct because the airflow should flow to the defroster ducts (vents) when the defrost position is selected.

The correct answer is C. SAE which stands for the Society of Automotive Engineers, is the standard that is used to measure viscosity (oil thickness). Answers A, B, and D are not correct because, even though these organizations do have established oil-related standards, they are not associated with the thickness (viscosity) of the oil.

The correct answer is D. Any of the above are correct. It is important to reset the oil life monitor (OLM) because the owner can then be notified by a message on the dash as to when the oil should be changed again. The vehicle’s owner’s manual, or service information or an Internet search can be used to determine how to reset the oil life monitor.

The correct answer is A. The best way to prevent air from getting trapped in the cooling system is to open the bleeder valve which is usually at the highest point of the cooling system, with the bleed valve open, air can escape as coolant is being added to the system. Answer B is not correct because Keeping the cap off the overflow container while filling the system would not result in allowing any air trapped in the cooling system to escape. Answer C is not correct because while pouring the coolant into the radiator opening slowly may help prevent air from being trapped in the system, air can still be trapped and can not get out unless a bleeder valve is open. (answer A). Answer D (all of the above) is not correct because only answer A is correct.

The correct answer is D. All of the above are correct. The Technician should check for any leakage out of the weep hole as well as check for looseness by grasping the drive pulley with the engine off. A pressure test of the cooling system can be used to check for leaks from the water pump gasket. Answers A, B, and C are not correct because all of the above are correct for what should be performed when checking a water pump.

The correct answer is D. Either throttle body cleaner or top engine cleaner can be used to clean the throttle body and air induction of an engine. Answer A (brake cleaner) is not the recommend product to use to clean the throttle plate.

The correct answer is B. The crankshaft changes the up and down motion of the poison and converts it to rotary motion through the throws where the connecting rods attach. Answer A (connecting rods) is not correct because while they do connect the piston to the crankshaft, they do not convert up and down motion to rotary motion. Answer C is not correct because the purpose and function of the camshaft is to operate the opening of the valves and it is not used to convert the up and down motion of the pistons to rotary motion. Answer D (harmonic balancer) is not correct because its purpose and function is to dampen and the oscillation forces created in the crankshaft and does not change the up and down motion of the pistons to rotary motion.

The correct answer is C. The purpose and function of valve springs is to close the valve. The valves are opened by the forces created by the lobes on the camshaft that then act on the pushrod (incorrect answer B) and then to a rocker arm (incorrect answer A) and finally to the stem of the valve. Answer D (valve retainer) is not correct because a valve retainer is used to keep the valve spring attached to the stem of the valve and does not cause the valve to close.

The correct answer is D. All of the above are correct. Answer A is correct because spark plug gap should be checked and corrected, if necessary, before installation. Answer B is also correct because a torque wrench should be used to tighten the spark plug to factory specifications. Answer C is also correct the sparkplug boot and wire (if equipped) should be inspected for any damage or excessive resistance.

The correct answer is B. When installing any engine part, the specified procedure is to start at the center and work toward the ends or the outside to spread any movement away towards the outside and not create forces that could crack or damage the part. An inch-pound torque is also required because most sheet metal parts such as valve covers and oil pans have a fastener torque specification listed in inch pounds. Answers A, C, and D are not correct because they don’t state to tighten from the inside outward or use an in-lb torque wrench.

The correct answer is B. Use only rubber hose designed for fuel vapors. The vapor in the evaporative emission control system are low pressure but contain fuel vapor that could harm other types of rubber hose. Answer A (rubber vacuum line) is not correct because it may not be able to withstand the vapors present in the evaporative emission control system. Answer C (high-pressure rubber hose) is not correct because while it may be able to handle the vapor in the evaporative emission control system, it is not e the recommended hose and may not be able to be routed in the same location as the original due to its thicker construction. Answer D (steel lines) is not correct because only the line type and construction designed for use in the evaporative emission control system should be used.

The correct answer is C. Most vehicle manufactures recommend that the pan fasteners all be removed except at one end. Then these end fasteners can be loosening to allow the pan to drop down which allows the fluid to be drained. Answer A is not correct because prying on a pan could distort the pan and is not the recommended process or procedure to follow. Answer B is not correct because while some older automatic transmissions were equipped with a drain plug, few if any are now so equipped. Answer D is not correct because the transmission does not need to be removed to remove the pan.

The correct answer is D. Either A or B are correct. Answer A is correct because most automatic transmission have the filter inside the unit requiring that the pan be removed to get access on most transmissions. Answer B s also correct because some automatic transmissions such as the Allison automatic transmission used in many trucks, use an external spin-on filter. They also use an internal filter that is only replace when the unit is overhauled. Answer C (inline the transmission cooling lines) is not correct because the filter is usually located under the lower pan of most automatic transmissions.

The correct answer is B. Before draining the manual transmission or transaxle, the filler plug should be checked to make sure that it can be removed. Failure to make sure that the unit can be refilled could result in having to remove the transmission/transaxle to have the fill plug removed as operating the vehicle without fluid in the transmission could destroy it. Answer A (check for any stored diagnostic trouble codes) is not correct because while the Technician could check for DTCs, this step is not needed or required to be performed before replacing the fluid in the manual transmission/transaxle. Answer C (replace the transmission mount) is not correct because while the Technician could replace the transmission mount if defective, this step is not needed or required to be performed before replacing the fluid in the manual transmission/transaxle. Answer D (check the fluid level in the hydraulic clutch master cylinder) is not correct because while the Technician could check the fluid level in the hydraulic clutch master cylinder, this step is not needed or required to be performed before replacing the fluid in the manual transmission/transaxle.

The correct answer is B. The photo shows excessive negative camber likely due to a broken suspension part. Answer A is not correct because even though some vehicle owners want their vehicle to have excessive negative camber, this is not normal and likely due to a broken suspension part. Answer C is not correct because the left rear wheel has excessive negative camber, not positive camber. Answer D is not correct because the left rear wheel has excessive negative camber, not positive caster.

The correct answer is D. Either change rear toe (answer A) or change rear camber (answer B) depending on the vehicle. The eccentric cam can be used to either adjust the rear toe or the rear camber depending on the vehicle. Answer A (change rear toe) is not correct because it is just one possible use depending on the vehicle. Answer B (change rear camber) is not correct because it is just one possible use depending on the vehicle. Answer C is not correct because rear caster is not adjustable on most vehicles.

The correct answer is C. The brake pedal depressor used to hold the brakes to keep the front wheel from rotating during a caster sweep. Answer A (used when adjusting toe) is not needed because the brakes do not need to be held stationary when adjusting toe. Answer B (to apply the brakes during a camber measurement) s not correct because the brakes do not need to be held stationary when adjusting camber. Answer D (to prevent the vehicle from falling off the alignment rack) is not correct because the vehicle should be secured on the alignment rack using chocks or the parking brake to keep the vehicle safely on the alignment rack and the service brakes should not need to be applied.

The correct answer is A. The steering wheel often needs to be held in the straight-ahead position while adjusting the tie rod sleeves used to adjust front toe. Answer B (hold the front wheels straight during a camber measurement) is not correct because the steering wheel does not need to be held steady when measuring camber. Answer B (hold the front wheels straight during a caster measurement) is not correct because the steering wheel does not need to be held steady when measuring caster. Answer D (to prevent the vehicle centered alignment rack) is not correct because the vehicle should be secured straight on the alignment rack when starting the alignment procedure and keep it is straight on the rack after not needed.

The correct answer is B. The cap on the master cylinder stats that “only DOT 4” fluid should be used in this Ford vehicle and that is what the Service Technician shroud use. Answers A, C, and D are not correct because only DOT 4 should be used in this vehicle. According to most vehicle manufactures, brake fluid type should not be mixed or substituted for another type other than what is specified to be used.

The correct answer is D. The tool is called a brake shoe clearance gauge and is used to adjust the drum brakes to closely match the drum before installing the brake drum. The lower part of the gauge is inserted into the drum and adjusted to fit. Then the upper part of the gauge is placed over the brake shores and adjusted until there is a slight drag with the gauge in place. By performing this operation, the drum brakes will be correctly adjusted with the proper amount of clearance when the drums are installed. Answers A, B, and C are not correct because the gauge shown is used to adjust drum brake shoes and not to measure rotors (answer A) or to measure brake drums (answer B) or to measure rotors or drums (answer C).

The correct answer is B. The letter EE are the coefficient of friction codes. The first “E” is the rating when the brakes are cold and the second “E” is the coefficient of friction rating for the disc brake pads when they are hot. The other answers are not related to the coefficient of friction codes and instead refer to the manufacture, composition code used by to the identity the material used or other information.

The correct answer is A. The digital micrometer is designed to be used to measure the thickness of disc brake rotors. Answers B, C, and D are not correct because this style micrometer is designed do only measure rotors and not brake drums (answer B), or either rotors or drums (answer C) or used to adjust drum brake shoe (answer D).

The correct answer is B. The coarse sponge-like tool is being used to clean the mating surface of the wheel hub to wheel surface. Answer A (machining a brake drum) is not correct because the tools used is not a precision tool and is used to simply remove rust and corrosion from the hub surface. Answer C (cleaning the threads of the lug nuts studs) is not correct because while the cleaner does have a hole in the center to go around the studs, it is designed to clean the hub surface around the studs and not the studs themselves. Answer D (removing a wheel stub from a rotor) is not correct because the tools is being used to clean and not used as a tool to remove a wheel stud.

The correct answer is C. This socket assortment includes the sockets needed to remove and install disc brake caliper retaining bolts (guide pins). Answers A, B, and D are not correct because normal tools are required to remove a master cylinder (answer A), or to remove and install a vacuum brake booster (answer B) or to remove drum brake wheel cylinders (answer D).

The correct answer is D. Both A and B are correct. Answer A (replace the disc brake pads) is correct because obviously the brake pads are worn and require replacement. Answer B (machine or replace the rotors) is also correct because it appears that the disc brake pads have worn the rotor. Answer C (either A or B) is not correct because both the disc brake pads and the rotor will require replacement or service and not just one or the other.

The correct answer is C. Only silicone or synthetic grease should be used on brake parts. Answers B, C, and D are not correct because using wheel bearing grease (answer A), or chassis grease (answer B) can cause dirt to be attracted to the grease making the parts stick which is t opposite of what the purpose of the grease is designed to do. Answer D (any of the above) is not correct because only silicone or synthetic grease should be used on brake parts.

The correct answer is A. When bleeding or flushing a hydraulic brake system, the bleeder valve should be opened to allow brake fluid to flow from the system to the receiving container. Answer B (the lower (brake line) is not correct because the brake line itself does not need to be loosen or removed when bleeding or flushing the brake system. Answer C (either the breeder or to the brake line) is not correct because the brake line itself does not need to be loosen or removed when bleeding or flushing the brake system. Answer D (both the bleeder valve and the brake line) is not correct because the brake line itself does not need to be loosen or removed when bleeding or flushing the brake system, just the bleeder valve.

The correct answer is D. Any or all of the above may or be required to be replaced. Answer A (wheel cylinder) is likely to require replacement because it appears that a lot of fluid has been leaking form the areas and this could be due to a blown wheel cylinder. Answer B (brake shoes) will also likely need to be replaced because with this much fluid leaking from somewhere, the lining must be soaked and therefore would require replacement. Answer C is also likely needed because the amount of fluid shown leaking could indicate a leaking rear axle seal.

The correct answer is C. Some manufacturers recommend that their replacement brake pads be bedded-in or burnished before returning the vehicle to the owner. After installing new pads, perform the following steps:

Step 1: Make 6 to 10 brake applications from approximately 35 mph (56 km/h) with moderate brake pedal force.

Step 2: Make an additional two to three hard brake applications from approximately 45 mph (72 km/h).

Note: Do not allow the vehicle to come to a complete stop. After preforming these brake applications, allow the brakes to cool completely before driving again.

Answers A, B, and D are not correct because they are not the procedure recommended by vehicle manufactures.

The correct answer is D. Any of the above are correct. Answer A is correct because the unit shown has a 16-pin connecter at one end that is attached to the data link connector (DLC) of the vehicle being serviced. The other end is installed into the power outlet of a jump box or the power outlet (lighter plug) of another vehicle. Battery power is then furnished to the vehicle through pins #16 and (power) and #4 (chassis ground) of the vehicle keeping all of the circuits alive when the battery is disconnected. Answer B (jump starting another vehicle) is correct because this could be done with this setup by connecting the lighter plug end it to a jump start battery pack, current could flow through to the battery terminals of the DLC thereby charging the battery. Then over a period of time this would allow the vehicle to crank and start once the dead battery has been charged. Answer C (charge a vehicle’s battery) is because this could be done with this setup by connecting the lighter plug end it to a jump start battery pack, current could flow through to the battery terminals of the DLC thereby charging the battery.

The correct answer is B. The bulb should be handled using a glove or a shop cloth to avoid touching the glass with fingers. Answer A is not correct because the headlight assembly is not being disturbed and unless the entire assembly is removed, there is no change in the headlight alignment and no correction is necessary. Answer C is not correct because the halogen bulb simply plugs into an electrical socket and no wiring is repair is needed or required. Answer D is not correct because the halogen bulb simply plugs into to an electrical socket and no wiring is repair is needed or required.

The correct answer is B. The anemometer is being used to measure the airflow from the dash outlets. If low airflow is detected then a further testing is needed but it could be due to a clogged cabin filter. Answer A (outlet temperature) is not correct because an anemometer is used to measure airflow and not temperature. Answer C (inlet temperature) is not correct because an anemometer is used to measure airflow and not temperature. Answer D (ambient air temperature) is not correct because an anemometer is used to measure airflow and not temperature.

The correct answer is B. Replace any serpentine belt that has more than three cracks in any one rib that appears in a 3-inch span. Answers A, C, and D are incorrect because those components do not cause this type of belt wear.

The correct answer is C. Inline fuel filters are usually attached to the fuel line with screw clamps or threaded connections and O-rings. The fuel filter must be installed in the proper direction, or a restricted fuel flow can result. Answers A or B only is incorrect because both types are used. Answer D is also wrong because at least one answer is correct.

The correct answer is D. The correct tool to remove this hose clamp is a set of hose clamp pliers. Answers A, B, and C are not the proper tool for removing this type of clamp.

The correct answer is A. The catalytic converter is placed as close to the engine as possible so that the heat can help the converter work most efficiently. B is a header pipe, C is a resonator, and D is the muffler.

The correct answer is B. Many tensioners have marks that indicate the normal operating tension range for the accessory drive belt. When the no longer line up the belt should be replaced. The marks are not timing marks (A). Answers C and D are incorrect because this is not the purpose of the marks.

The correct answer is C. Vehicle manufacturers size the onboard DEF storage tank so that it needs to be refilled at about each scheduled oil change or every 7,500 miles (12,000 km). Answer A is incorrect because this is not often enough. Answer B is too often. Answer D is incorrect because if the tank is run until empty the engine may not start.

The correct answer is A. When installing spark plugs, always use the correct tightening torque to ensure proper heat transfer from the spark plug shell to the cylinder head. This includes using a torque wrench. Answers B, C, or D are all incorrect techniques for installing spark plugs.

The correct answer is D. All these tools can read emissions related DTCs, but the code reader is not the best to use since it cannot read other system DTCs. Answers B and C are better choices because they can read other systems, also.

The correct answer is B. If the fluid level is too low, a fluid leak is the most likely cause and should be corrected as soon as possible to prevent damage, wear, or harm to the transmission/transaxle parts due to low fluid level. Answers A, C, and D are not the correct next step; the leak should be found and corrected first.

The correct answer is D. Most inner CV joints can be separated from the transaxle with a prybar. A hammer (A), impact wrench (B), or axle jack (C) are not the correct tools for removing a drive axle from the transaxle.

The correct answer is C. A broken transmission mount allows the engine/transaxle to shift position, changing the angle of the drive axles. The result is a shaking or vibration in the vehicle. When decelerating the engine/transaxle falls back into position, causing a loud knocking sound. Answer D is incorrect because at least one of the answers is correct.

The correct answer is C. Axle shaft endplay (A) can be checked by mounting a dial indicator on the brake assembly or axle housing with the indicator stylus on the axle. The indicator will measure the endplay as the axle is moved in and out. While pushing the axle inward to remove any endplay, the set up can also measure lateral (side-to-side) (B) of the axle flange. Lateral runout of 0.005 inch (0.1 mm) or less is acceptable. Answer D is incorrect because at least one answer is correct.

The correct answer is C. The brake caliper (A) and rotor (B) must be removed to access the wheel bearing. After the mounting bolts are removed (D) the wheel bearing is removed from the knuckle. The knuckle is not removed so, therefore, the correct answer is C.

The correct answer is C. A retainer-plate-type axle uses a ball bearing (A), seal (C), and a bearing retainer ring (B), which is a press fit into the axle shaft. Item D is the retainer plate which is fastened with studs and nuts.

The correct answer is B. Either two-wheel drive or four-wheel drive may be selected. The mode shift is achieved using a floor-mounted lever to engage and disengage a clutch inside the transfer case. This shift is usually performed when the vehicle is stopped. A foot clutch or column mounted lever is not used to select two or four wheel drive. Answer D is incorrect because at least one answer is correct.

The correct answer is A. Most four- wheel-drive-related trouble codes will be “B” (body) codes, “C” (Chassis) codes. Sometimes the diagnostic trouble code will also have a two-digit subcode that gives additional information to help the technician find the fault. A fault with the shift motor will not set a type P or U DTC. Answer D is incorrect because at least one answer is correct.

The correct answer is A. A tight stud should be removed using a pressing tool so as not to bend the axle flange. Use a remover over the stud and tighten until the stud is removed out the back. A hammer (B) can bend the axle flange or damage the wheel bearing. A punch (C) or die grinder (D) are not used to remove a wheel stud from a drive axle.

The correct answer is D. Most replacement pumps are not equipped with a pulley. The old pulley must be removed and installed on the new pump. The pulley must be removed and installed with a pulley removal and installation tool. Answers A, B, and C are incorrect because these are not typical tools needed to replace a power steering pump.

The correct answer is D. Idler arm inspection is performed by using hand force of 25 pounds (110 N-m) up and down on the arm. If the total movement exceeds 1/4 inch (6 mm), the idler arm should be replaced. The component is not a pitman arm (A), drag link support (B), or a center link (D).
