Fixed Displacement A/C Compressor

COMPRESSOR, A/C - FIXED DISPLACEMENT

On 2.2L diesel engine equipped models, the Denso fixed displacement A/C compressor is driven by the engine through an electric clutch, drive pulley and belt arrangement. This A/C compressor is lubricated by refrigerant oil that is circulated throughout the refrigerant system with the refrigerant.

The A/C compressor draws in low-pressure refrigerant vapor from the A/C evaporator through the suction port, then compresses the refrigerant into a high-pressure, high-temperature refrigerant vapor that is pumped to the A/C condenser, through the compressor discharge port.

CAUTION: Be certain to adjust the refrigerant system oil level when replacing an A/C compressor Refrigerant Oil Level . Failure to properly adjust the refrigerant oil level can prevent the A/C system from operating as designed and can cause serious A/C compressor damage.

The Denso fixed displacement A/C compressor cannot be repaired and must be replaced if inoperative or damaged. The compressor clutch, pulley and bearing assembly, and clutch coil are available for service if inoperative or damaged. If an internal failure of the A/C compressor has occurred, the A/C condenser/receiver/drier assembly must also be replaced A/C Condenser - Removal.
