Two technicians are discussing variable displacement piston compressors. Technician A says that the wobble plate is moved to the high-angle position for maximum output when the cooling load is high. Technician B says that the wobble-plate angle is
controlled by the pressure in the crankcase of the compressor. Which technician is correct? A) Technician A only B) Technician B only C) Both technicians A and B D) Neither technician A nor B
In regards to pressure testing cooling systems and pressure caps identify the INCORRECT statement.
A. The radiator cap when tested should not open until the system pressure indicated on the cap has been surpassed. B. Always build system pressure up 25% over the rated capacity when checking for cooling system leaks. C. When the cooling system has been allowed to cool down and radiator and heater hoses have been collapsed is an indication that the vacuum relief portion of the radiator cap may be defective. D. Never build system pressure more than 10% of the systems rated capacity when testing for coolant leaks.
