- Technician A says that some refrigerant leaks can also be traced to pinholes in the evaporator caused by acid, which forms when water and refrigerant mix. Technician B says that leaks are most often found at the compressor hose connections and at the various fittings and joints in the system. Who is correct? Technician A only Technician B only Both A and B 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_forwardTechnician A says that evacuating (pumping down) an air-conditioning system removes air and moisture from the system. Technician B says that evacuating (pumping down) an air-conditioning system removes dirt particles from the system. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forward
- 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? Technician A Technician B Both A and B Neither A nor Barrow_forwardTechnician 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_forwardWhile checking the condition of a cars ATF: Technician A says that if the fluid has a dark brownish or blackish color and/or a burned odor, the fluid has been overheated. Technician B says that if the fluid has a milky color, this indicates that engine coolant has been leaking into the transrnissions cooler. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
- While diagnosing the cause of air bubbles in the coolant recovery tank: Technician A checks for a bad head gasket. Technician B checks the radiator cap. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardAll of the following are true statements about flushing an A/C system after a compressor failure, except The condenser must be flushed and the receiver/ dryer replaced. Filter screens are sometimes located in the suction side of the compressor and in the receiver/dryer. These screens confine foreign material to the compressor, condenser, receiver/dryer, and connecting hoses. Use only CFCs for flushing. After the system has been flushed, be sure to oil all components that require it. Some manufacturers recommend replacing the clogged components and installing a liquid line (inline) filter just ahead of the expansion valve or orifice tube instead of flushing the system.arrow_forwardWhich is not a pressure or force acting on a TXV diaphragm?
