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 following air conditioning (A/C) component installation general procedure. For additional information, refer to REFRIGERANT SYSTEM FILTERING FOLLOWING AIR CONDITIONING (A/C) COMPONENT INSTALLATION .
- Install a new A/C evaporator core orifice. For additional information, refer to EVAPORATOR CORE ORIFICE .
- Remove the drive belt. For additional information, refer to BELT ROUTING .
- If equipped, disconnect the engine block heater electrical connector.
- Disconnect the A/C clutch field coil electrical connector.
CAUTION:
- Plug all ports to prevent contamination from dirt or moisture.
- 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.
- Remove the bolts and the A/C compressor.
- To install, reverse the removal procedure.
- Lubricate the new A/C compressor with the correct amount of PAG Compressor Oil. For additional information, refer to REFRIGERANT OIL ADDING .
- Lubricate the new A/C manifold O-ring seals with PAG Compressor Oil.
- Apply Pipe Sealant with Teflon@ to the threads of the A/C manifold and tube assembly bolt.
- Recharge the A/C system. For additional information, refer to AIR CONDITIONING (A/C) SYSTEM EVACUATION AND CHARGING .
