ASE T8 Preventative Maintenance
Inspection (PMI) Practice Test
With a cold engine, the coolant level in the radiator is too low, but the coolant level in the
recovery tank is at the HOT mark. There have been no complaints of the engine
overheating. Which of these could be the cause of the low coolant level in the radiator?
(A) A failed radiator cap
(B) A stuck-closed engine coolant thermostat
(C) A stuck-open engine coolant thermostat
(D) An incorrect coolant-to-water mixture ratio - ANS-A
Which of these should a PMI technician do to properly obtain an engine oil sample?
(A) After removing the oil filter, pour some oil from the oil filter into a sample bottle.
(B) Dip the sample bottle into the oil after it has drained into a catch pan.
(C) After removing the drain plug, immediately catch some oil into a sample bottle.
(D) After removing the drain plug, allow some oil to drain before obtaining an oil sample.
- ANS-D
During a visual inspection, oil is observed around the shaft area of a viscous-type fan
clutch. This could be caused by:
(A) an overheated engine.
(B) a failed viscous clutch bearing.
(C) a failed fan controller.
(D) a broken bi-metal spring on the clutch. - ANS-B
During a PM inspection, the technician observes black streaks/residue at the end of the
charge air cooler hoses on the pipe between the cooler and the intake. Which of these
could be the cause?
(A) A stuck-closed EGR valve
(B) A stuck-open EGR valve
(C) Loose hose clamps
(D) A leaking exhaust manifold gasket - ANS-C
, During a PMI, the technician finds excessive oil residue in the engine compartment.
When the engine is started, it is discovered that the engine has too much crankcase
pressure. Which of these could be the cause?
(A) An incorrect valve adjustment
(B) A restricted crankcase ventilation system
(C) Fuel contamination in the engine oil
(D) Coolant contamination in the engine oil - ANS-B
When checking HVAC system performance, the technician observes that air flow from
the dash vents is normal. With the A/C ON and the temperature selector set to COLD,
the temperature of the air from the dash vents is warm. Which of these could be the
cause?
(A) A restricted cabin air filter
(B) A binding recirculation door actuator
(C) A binding blend door actuator
(D) An internally restricted heater core - ANS-C
The air suspension system for the truck cab is being checked. A properly adjusted
system should be set to inflate:
(A) to within 2" of full extension.
(B) to within 4" of full extension.
(C) so the cab is within 2" of full compression.
(D) so the cab is sitting at the center of the stroke/travel. - ANS-D
With the engine at normal operating temperature, the oil pressure is below specification
during an instrument check.
Technician A says that a mechanical gauge can be used to verify the oil system
pressure.
Technician B says that the engine oil should be checked for contamination.
Who is right?
(A) A only
(B) B only
(C) Both A and B
(D) Neither A nor B - ANS-C
