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 - ANSWER 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. - ANSWER 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. - ANSWER 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 - ANSWER 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 - ANSWER 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 - ANSWER C
The air suspension system for the truck cab is being checked. A properly adjusted system should be set
to inflate:
