COMPRESSOR REPLACEMENT

TOOLS REQUIRED
- J 43600 ACR 2000 Air Conditioning Service Center
- J 39400-AHalogen Leak Detector

REMOVAL PROCEDURE
1. Recover the refrigerant from the system. Refer to Refrigerant Recovery and Recharging.
2. Disconnect the negative battery cable.
3. Remove the accessory drive belt from the compressor.
4. Remove the front air deflector.
5. Remove the right front tire.
6. Remove the right wheelhouse extension.
7. Disconnect the brake line retaining clip from the frame in order to allow movement of the brake lines during removal of the A/C compressor.




8. Disconnect the suction hose fitting from the compressor.

IMPORTANT: Seal the A/C compressor suction and discharge ports after the hoses are removed in order to keep contaminants from entering the A/C compressor, and to keep oil from draining out of the A/C compressor during removal.
All A/C lines, hoses and components should always be sealed after component removal in order to avoid excessive moisture contamination to the A/C system during servicing.




9. Disconnect the discharge hose fitting from the compressor.




10. Disconnect the compressor electrical connector.
11. Remove the lower alternator bolt.




12. Remove the A/C compressor mounting fasteners (1, 2, 3, 4).




13. Remove the A/C Compressor (2) mounting stud (1).




14. Rotate the A/C compressor, in order to allow the A/C compressor to exit through the wheelhouse extension opening.
15. Remove the A/C compressor.
16. Balance the compressor oil. Refer to Compressor Oil Balancing.

INSTALLATION PROCEDURE




1. Install the compressor through the wheelhouse extension opening.
2. Rotate the compressor in order to fit the compressor though the wheel house extension opening.




3. Install A/C compressor (2) mounting stud (1).
4. Install the lower alternator bolt.




5. Install the A/C compressor mounting fasteners (1, 2, 3, 4) and hand tighten the fasteners.

NOTE: Refer to Fastener Notice in Service Precautions.

Tighten the fasteners in the following sequence:

Tighten

2. Tighten the A/C compressor mounting bolts (2, 3) to 50 N.m (37 lb ft)
3. Tighten the last A/C compressor mounting bolt (4) to 25 N.m (18 lb ft)




4. Connect the compressor electrical connector.




5. Connect the discharge hose fitting to the compressor.

Tighten
Tighten the discharge hose fitting to the compressor to 20 N.m (15 lb ft).




6. Connect the suction hose fitting to the compressor.

Tighten
