Technician A says that before installing an oil pump, it should be
primed with clean engine oil. Technician B says that before
installing an oil pump, the position of the pickup screen should be
checked to make sure it fits closely to the bottom of the oil pan.
Who is right? - Answer✔️✔️-The correct answer is C, both
technicians are right.
~The oil pump should be filled with oil during engine reassembly to
prevent it from cavitating or sucking air during engine start-up. To
prevent the pickup from sucking air and subsequent oil starvation
and engine damage, make sure the pickup screen is positioned
close to the bottom of the oil pan to ensure it is always submerged
in oil.
All of the following can cause low oil pressure EXCEPT:
A. diluted engine oil
B. worn pistons
C. excessive bearing clearance
D. clogged oil pump pickup - Answer✔️✔️-The correct answer is B.
~Worn pistons can cause noise and accelerate ring and bore wear,
but would not cause low oil pressure. Diluted oil, excessive bearing
clearance and a clogged pump pickup can all cause low oil
pressure.
Technician A says that the thermostat controls maximum engine
temperature. Technician B says if the engine continously runs hot,
install a cooler thermostat. Who is right? - Answer✔️✔️-The correct
answer is D, neither technician is right.
~The thermostat's function is to allow the engine to come to
operating temperature quickly and them maintain a minimum
operating temperature. The PCM bases fuel mixture, ignition
timing, EGR operation and other functions in part on input
regarding coolant temperature. Only the correct heat range
thermostat should be installed. If the thermostat is good and the
engine runs hot, another problem exists.
All of the following could cause an engine to overheat EXCEPT:
A. defective fan clutch
B. clogged cooling system
C. broken fan shroud
D. stuck open thermostat - Answer✔️✔️-The correct answer is D.
