HIGH PRESSURE RELIEF VALVE
A high pressure relief valve is located on the compressor cylinder head at the rear of the A/C compressor. 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.
