About

The Automotive Service Excellence (ASE) exam is part of the Automobile & Light Truck certification test series and focuses on practical day-to-day encounters and situations related to engine repair. Those who pass the ASE test are recognized as an Automotive Professional, however, re-testing is required every 5 years with an exam that is only half the time and length.

The test will encompass a number of key repair areas, which any professional must be proficient in. These include repair and diagnosis of Cylinder Head and Valve Train, Engine Block, Fuel, Electrical, Ignition and Exhaust Systems, General Engine, and Lubrication and Cooling Systems. 

The ASE A1 Test Structure

The (ASE) A1 test includes a total of 60 questions to be solved in 75 minutes. 10 out of these 60 questions will not be graded.

The 50 graded ASE exam questions are broken down as follows:

 

1. General Engine Diagnosis – 15 questions.

What to look out for? Aside from checking, identifying, and solving issues like excessive oil consumption, coolant consumption, and you will need to understand how to answer customer concerns.

 

2. Repair and diagnosis of Cylinder Head and Valve Train – 10 questions.

What to look out for? From inspecting the cylinder heads for damage to repairing damaged threads and replacing valves, springs, and steam seals these questions will ensure that you know your cylinder head and valves inside and out. Additionally, keep in mind you will also be tested on pushrods, rocker arms, pivots, and shafts. 

 

3. Repair and diagnosis of Engine Block – 10 questions.

What to look out for? This part of the ASE test deals with everything to do with engine blocks, including dismantling and re-assembling, understanding all parts, preparing specific components, and more.  You may be asked about inspecting and replacing pans and covers, checking flywheel ring gear for cracks and deciding if cylinder deactivation system is in need of fixing.

 

4. Repair and diagnosis of Lubrication and Cooling Systems – 8 questions.

What to look out for? Do you know how to inspect thermostat housing, test the coolant by-pass, or reinstall the thermostat? This area of the test will also call upon you to inspect pressure relief devices, disassemble and reassemble an oil pump, do an oil pressure and dye test while knowing the ins and outs of the cooling and heater systems.  

 

5. Fuel, Electrical, Ignition and Exhaust Systems – 7 questions.

What to look out for? Lastly, you will be challenged throughout the ASE test in your understanding of fuel injection system components, making an investigation, analysis, and prognosis for turbocharger system, and successfully replacing. This section will also look at exhaust systems, air filters, cranking systems, and more.


Sample Questions:

 

Sample Question 1: A vehicle with a cold engine emits a short cloud of blue smoke just after being started. There are no signs of smoke in other driving conditions. This usually indicates:

  1. a) worn piston rings
  2. b) oil pressure is too high
  3. c) worn valve stem gaskets
  4. d) blocked oil passages

 

 The correct answer is C.

Explanation: Valve stem gaskets that do not seal properly allow too much oil to drip down into the combustion chamber where it is burned. There is no noticeable smoke while the engine is running, as the amount of oil per stroke is too small. However, when the engine shuts down, the oil remaining in the cylinder head slowly drips down into the combustion chambers, summing up to a quantity that will produce more smoke at the restart.

 

Question 2: A warped cylinder head is usually a sign of engine damage caused by:

  1. a) prolonged drive with engine pre-detonation
  2. b) engine overheating
  3. c) timing failure
  4. d) any of the above

 

The correct answer is B.

Explanation: When overheated, the cylinder head will warp as it would suffer excessive heat and tensions through all of its volume. Pre-detonation would cause local damage, usually cracks in piston, valves or head. Timing failure would result in bent or broken valves or damaged pistons.

 

Question 3: Variable valve timing (VVT) can be used to replace the function of:

  1. a) amount of intake air measurement device (MAF or MAP)
  2. b) exhaust gas recirculation system
  3. c) valve clearance adjustment
  4. d) throttle plate

 

The correct answer is B.

Explanation: Exhaust gas recirculation (EGR) injects a portion of exhaust gases back into the intake, so they have burned again, in order to lower emissions. With VVT, an exhaust valve can be kept open longer, allowing some exhaust gases to be sucked back into the cylinder and burn again. This eliminates the needforEGR system.
