Ford Mustang (1999-2004) Service Manual: A/C Compressor Pressure Relief Valve

An A/C compressor pressure relief valve is incorporated into the compressor A/C manifold and tube to:

• relieve unusually high refrigerant system discharge pressure buildups. For specifications regarding operating pressure(s), refer to Section.
• prevent damage to the A/C compressor and other system components.
• avoid total refrigerant loss by closing after the excessive pressure has been relieved.

A/C Condenser Core

The A/C condenser core has the following characteristics:

• It is an aluminum fin and tube design heat exchanger located in front of the vehicle radiator (8005).
• It cools compressed refrigerant gas by allowing air to pass over fins and tubes to extract heat and by condensing gas to liquid refrigerant as it is cooled.
