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
A vehicle has had several radiator
replacements, and each time there has been
pinhole leaks in the aluminum. Technician A
states that the engine coolant may need to be
exchanged more often. Technician B states
that the engine grounds should be inspected
closely since this could be the cause. 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
Technician A uses sandpaper to remove carbon deposits from turbocharger wastegate parts. Technician B scrapes off heavy deposits before attempting to clean the unit. Who is correct?

- Technician A says that the presence of oil around a fitting of an air-conditioning line may indicate an oil leak but not a refrigerant leak. Technician B says that using an electronic leak detector is the best way to find the source of a refrigerant leak. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardTechnician A says that if the PCV valve or connecting hoses become clogged, excessive pressure will develop in the crankcase and can cause oil leaks. Technician B says that if the PCV valve or connecting hoses become clogged, oil may be pushed into the air cleaner or cause it to be drawn into the intake manifold. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhile discussing the results of an oil pressure test: Technician A says that when the fluid pressures are high, internal leaks, a clogged filter, low oil pump out put, or a faulty pressure regulator valve are indicated. Technician B says that if the fluid pressure increased at the wrong time, an internal leak at the servo or clutch seal is indicated. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
- A reddish-colored oil is discovered to be leaking during an engine oil change and inspection: Technician A says it may be from a leak in the cooling system. Technician B says it may be leaking transmission fluid. Who is correct?arrow_forwardWhile determining the cause for air leaking out of the oil throttle body during a cylinder leakage test: Technician A says that a burnt intake valve is indicated. Technician B says that a warped cylinder head or bad head gasket is indicated. Who is correct? Technician A Technician B Both A and B d. Neither A nor Barrow_forwardWhile bleeding air from a cooling system: Technician A loosens a heater hose at its highest point Technician B uses air bleed valves. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- Which of the following is not an effective way to determine if an engine has an internal coolant leak? Performing a pressure test on the system Visually inspecting the exhaust, coolant, and engine oil Using a dye penetrant and black light Using a combustion leak testerarrow_forwardWhile discussing the reasons for resurfacing a cylinder head; Technician A says it should be resurfaced to make it flat and very smooth so the head gasket can seal properly during engine assembly. Technician B says that it can be resurfaced to raise the compression. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhen performing a coolant pressure test, Technician A says to pressurize the system to the pressure shown on the radiator cap. Technician B says that the coolant should be drained before performing the test. Who is correct? Select one: a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
- While discussing the cause of an oil leak in an axle housing, Technician A says if the fluid leaks past the threads of the drive pinion nut, the leak can be corrected by installing a copper washer under the nut. Technician B says fluid leakage past the stud nuts that hold the carrier assembly to the axle housing can be corrected by applying thread or gasket sealer on the threads and tightening the nuts to specifications. Who is correct?arrow_forwardThe presents of air in the cooling systems indicates the head gasket is faulty? True or falsearrow_forwardTrue or False? A compression gauge will show the amount of air leaking through a cylinder as a percentage.arrow_forward
