DESCRIPTION
A/C COMPRESSOR
The A/C system uses a Denso 10S17C ten cylinder, double-acting swash plate-type A/C compressor (1). This A/C compressor has a fixed displacement of 170 cubic centimeters (10.374 cubic inches), and has both the suction and discharge ports (2) located on the cylinder head (3) at the rear of the compressor.
A label identifying the use of R-134a refrigerant is located on the A/C compressor.
HIGH PRESSURE RELIEF VALVE
A high pressure relief valve is located on the compressor cylinder head at the rear of the A/C compressor (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING/COMPRESSOR-A/C - DESCRIPTION). This mechanical valve is designed to vent refrigerant from the A/C system to protect against damage to the A/C compressor and other A/C system components caused by condenser air flow restriction or an overcharge of refrigerant.
