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

While discussing the operation of air-conditioning systems: Technician A says that in order for the refrigerant to release heat, it must be at a low temperature and pressure. Technician B says that in order for the refrigerant to absorb heat, it must be at a high temperature and pressure. Who is correct? Technician A Technician B Both A and B Neither A nor B
While discussing an inoperative blend air door: Technician A says that to check the proper functioning of the ductwork, move the temperature control lever to see if any change at the doors occurs. If it does not, shut off the air conditioner and turn on the heater. Move the temperature control arm again to see if any change occurs. If not, check the cable and the flap door connected to the temperature control lever. Technician B says that in some cases you can reach under the dash to reconnect the cable or free a stuck flap.

Technician A says that air in the system can cause excessive pressure within the system, restricting the refrigerants ability to change its state from gas to liquid within the refrigeration cycle. Technician B says that moisture can cause freeze-up at the cap tube or expansion valve, which restricts refrigerant flow or blocks it completely. Who is correct? Technician A only Technician B only Both A and B Neither A nor B

1-While refilling an 8-quart (7.57 L) system with coolant: Technician A initially puts in 4 quarts (3.78 L) of straight coolant and tops it off with water. Technician B fills the system with the correct mixture, tightens the radiator cap, and then checks for leaks. Who is correct? 2-While checking for conditions that might cause coolant electrolysis: Technician A places the positive lead of a voltmeter into the coolant and connects the negative lead to a ground. Technician B checks for the presence of voltage in the coolant with the ignition off. Who is correct? 3-Technician 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? 4-While bleeding air from a cooling system: Technician A loosens a heater hose at its highest…
