What Topics Does the ASE A1 Test Cover?

An ASE A1 Test has seven main categories:

  1. Engine Repair Basics includes understanding internal combustion gasoline and diesel engines, their components, and their operations. The questions here cover engine cycles and your ability to identify and explain the function of essential engine parts.
  2. Engine Diagnosis involves identifying symptoms of engine issues, interpreting diagnostic trouble codes (DTCs), and effectively using diagnostic tools and equipment. You’ll need to perform compression tests, leak-down tests, and scan tools to diagnose engine performance problems.
  3. Engine Disassembly and Reassembly involve removing and reinstalling engine components, such as cylinder heads, pistons, crankshafts, and timing belts or chains. You should know proper torque specifications, gasket sealing techniques, and specialized engine repair tools.
  4. Cylinder Head and Valve Train Service includes inspecting and servicing cylinder heads, valves, valve springs, and camshafts. You must know how to measure valve clearances, replace valve seals, and perform valve adjustments. This section also covers function and service procedures for overhead camshaft (OHC) and overhead valve (OHV) engines.
  5. Engine Block and Crankshaft Service involves inspecting and servicing the engine block, cylinders, crankshaft, and connecting components. This includes checking cylinders and crankshaft journals for wear and replacing main and rod bearings.
  6. Lubrication and Cooling Systems tests your ability to understand the operation, components, and repair issues of oil pumps and filters, radiators, water pumps, and thermostats.
  7. Timing Belts and Chains contains questions about inspecting, replacing, and adjusting timing belts and chains. Topics include setting engine timing, identifying worn or damaged components, and correctly using timing marks.
