Students have asked these similar questions
A vehicle is having its water pump replaced.
When the water pump is removed, severe
corrosion is found on the water pump
impeller, and inside the engine. Technician A
states that the radiator cap may be
overpressurizing the system. Technician B
states that the vehicle may have been run
with 100% water in the cooling system for
some time. Who is correct?
Select one:
a. Technician A only
b. Technician B only
c. Both Technicians A and B
d. Neither Technician A nor B
A technician is inspecting a vehicle and finds
the upper radiator hose is collapsed, and the
cooling system pulled into a vacuum when
cold. Technician A states that a leak in the
surge tank could be the cause. Technician B
states that the radiator cap is most likely
defective. Who is correct?
Select one:
a. Technician A only
b. Technician B only
c. Both Technicians A and B
d. Neither Technician A nor B
An overheating vehicle is being discussed. Technician A states that the vehicle may be overheating becuase the heater control valve is stuck closed. Technician B states that the vehicle may be overheating because the PCM in not energizing the cooling fan relay. Who is correct?
