Air Conditioning (A/C) Compressor

Removal and Installation

CAUTION: To prevent refrigerant system contamination, if you are installing a new A/C compressor because the A/C compressor has failed internally, you must use the following procedures:

NOTE: Installation of a new suction accumulator is not necessary when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

NOTE: If an A/C Flusher is available, carry out the air conditioning (A/C) system flushing general procedure. For additional information, refer to AIR CONDITIONING (A/C) SYSTEM FLUSHING.

NOTE: If the A/C Flusher is not available, carry out the refrigerant system filtering air conditioning (A/C) component installation general procedure. For additional information, refer to REFRIGERANT SYSTEM FILTERING FOLLOWING AIR CONDITIONING (A/C) COMPONENT INSTALLATION.

1 Install a new A/C evaporator core orifice. For additional information, refer to EVAPORATOR CORE ORIFICE.
2. Remove the drive belt. For additional information, refer to ACCESSORY DRIVE BELT.




3. If equipped, disconnect the engine block heater electrical connector.




4. Disconnect the A/C clutch field coil electrical connector.

CAUTION: Plug all ports to prevent contamination from dirt or moisture




5. Remove the A/C manifold and tube assembly bolt from the top of the A/C compressor and disconnect the A/C manifold and tube assembly.




6. Remove the bolts and the A/C compressor.
7. To install, reverse the removal procedure.
1. Lubricate the new A/C compressor with the correct amount of PAG Compressor Oil. For additional information, refer to REFRIGERANT OIL ADDING.
2. Lubricate the new A/C manifold O-ring seals with PAG Compressor Oil.
3. Apply Pipe Sealant with Teflon(R) to the threads of the A/C manifold and tube assembly bolt.

8. Recharge the A/C system. For additional information, refer to AIR CONDITIONING (A/C) SYSTEM EVACUATION AND CHARGING.
