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.
A/C Compressor and Clutch Assembly
NOTE: Internal A/C compressor components are not serviced separately.
The FS-10 A/C compressor
is serviced only as an assembly. The A/C clutch pulley, A/C clutch field coil
(19D798) and the shaft

Component Tests
Battery-Load Test
1. With the engine running, turn the A/C on, the blower motor on high
speed and the headlamps
on high beam.
2. Increase the engine speed to approximately 2,000 rpm. The voltage
should increase a minimum
of 0.5 volt above the ba ...
