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, see AIR CONDITIONING (A/C) SYSTEM FLUSHING.

NOTE: If the A/C Flusher is not available, carry out the refrigerant system filtering following air conditioning (A/C) component installation general procedure.

1. Install a new A/C evaporator core orifice.
2. Remove the 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. See REFRIGERANT OIL ADDING.
2. Lubricate the new A/C manifold O-ring seals with PAG Compressor Oil.
3. Apply Pipe Sealant with Teflon� to the threads of the A/C manifold and tube assembly bolt.

8. Recharge the A/C system. See AIR CONDITIONING (A/C) SYSTEM EVACUATION AND CHARGING.
