A/C Compressor

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 the flushing of the air condition system prior to installing a new air conditioning compressor.
- If A/C flushing equipment is not available, carry out the filtering of the air conditioning system after a new air conditioning compressor has been installed. See REFRIGERANT SYSTEM FILTERING AFTER A/C COMPRESSOR REPLACEMENT.
- Install a new evaporator core orifice as directed by the A/C flushing or filtering procedure. See EVAPORATOR CORE ORIFICE REMOVAL/INSTALLATION.
- Replace the receiver/drier as directed by the A/C flushing or filtering procedure. See RECEIVER/DRIER REMOVAL/INSTALLATION.

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. If flushing of the refrigerant system has not been performed, recover the refrigerant; see REFRIGERANT SYSTEM TESTS.
2. Remove the accessory drive belt from the A/C compressor pulley. See DRIVE BELT REMOVAL/INSTALLATION.




3. Remove the bolts and detach the power steering fluid reservoir.




4. Remove the bolts and the bracket.




5. Disconnect the electrical connector.




6. Loosen the bolt and disconnect the compressor manifold and tube assembly from the A/C compressor.




7. Remove the pin-type retainers and position aside the inner fender well access cover.

NOTE: The two lower nuts and studs are accessible through the inner fender well.

8. Remove the four nuts, four studs, and the A/C compressor.
- Discard the O-ring seals.

9. To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the A/C compressor clutch field coil and the A/C clutch plate must be transferred from the old unit. See MAGNETIC CLUTCH REMOVAL/INSTALLATION.
- Lubricate the refrigerant system with the correct amount of clean refrigerant oil. See REFRIGERANT OIL ADDITION.
- Evacuate, leak test, and charge the refrigerant system. See REFRIGERANT SYSTEM TESTS.
- Install new O-ring seals lubricated in clean refrigerant oil.

10. Evacuate, leak test, and charge the refrigerant system. See REFRIGERANT SYSTEM TESTS
