Compressor HVAC: Service and Repair

REMOVAL

CAUTION: When installing a new A/C compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning system:
^ If A/C flushing equipment is available, carry out flushing of the air conditioning system.
^ If A/C flushing equipment is not available, carry out filtering of the air conditioning system.
^ Install a new evaporator core orifice.
^ Install a new suction accumulator.

NOTE: Replacement of the suction accumulator is not required 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.

1. Perform the Refrigerant Discharging and Recovery Procedure.
2. Remove the accessory drive belt from the A/C compressor pulley.







3. Disconnect the electrical connector.







4. Disconnect the compressor manifold and tube assembly from the A/C compressor.
1 Loosen the bolt.
