Compressor Hose Assembly Replacement

REMOVAL PROCEDURE




1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging.Service and Repair

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.

2. Disconnect the negative battery cable.
3. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

IMPORTANT: Prior to removal, take note of the compressor hose routing and orientation between the compressor and condenser.

4. Using a back-up wrench on the condenser fitting (2), loosen the compressor hose fitting (1) from the condenser.

IMPORTANT: Cap or tape the open compressor hose and the condenser immediately.




5. Disconnect the compressor hose from the condenser, discard the O-ring seal and cap or tape the compressor hose and the condenser to prevent contamination.




6. Lower the vehicle; leave the vehicle on the hoist.
7. Remove the battery heal shield.
8. Remove the compressor hose to compressor retaining bolt.

IMPORTANT: Cap or tape the open compressor hose and the compressor immediately.

9. Disconnect the compressor hose from the compressor, discard the seal washers and cap or tape the hose end and the compressor to prevent contamination.




10. Remove the compressor hose to accumulator retaining bolt.

IMPORTANT: Cap or tape the open compressor hose and the accumulator immediately.

11. Disconnect the compressor hose from the accumulator, discard the O-ring seal and cap or tape the compressor hose and the accumulator to prevent contamination.
12. Remove the compressor hose from the vehicle.

INSTALLATION PROCEDURE




1. Install the compressor hose into position in the vehicle.
2. Remove the cap or tape from the compressor hose and the accumulator.
3. Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the compressor hose and the accumulator.
4. Lightly coat the O-ring seal (1) with mineral base 525 viscosity refrigerant oil.

IMPORTANT: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the O-ring seal to enter the refrigerant system.

5. Carefully slide the new O-ring seal (1) onto the compressor hose until seated.

Leave a light coating of the refrigerant oil to remain on the compressor hose in the area indicated (2) ONLY.




6. Install the compressor hose to the accumulator.

NOTE: Refer to Fastener Notice in Service Precautions.

7. Install the compressor hose to accumulator retaining bolt.

Tighten
Tighten the compressor hose to accumulator retaining bolt to 20 N.m (15 lb ft).




8. Remove the cap or tape from the compressor hose end (2) and the compressor (3).
9. Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the compressor hose (2) and the compressor (3).
10. Lightly coat the new seal washers (1) with mineral base 525 viscosity refrigerant oil.

IMPORTANT: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the seal washers to enter the refrigerant system.

11. Carefully slide the new seal washers (1) onto the compressor hose (2) until seated.




12. Install the compressor hose to the compressor.
13. Install the compressor hose to compressor retaining bolt.

IMPORTANT: After tightening the compressor hose (3) to the compressor (2), there should be a slight sealing washer gap (1) of approximately 1.2 mm (3/64 in) between the compressor hose (3) and the compressor (2).




14. Tighten the compressor hose to compressor retaining bolt.

Tighten
Tighten the compressor hose to compressor retaining bolt to 26 N.m (19 lb ft).




15. Raise the vehicle.
16. Route the compressor hose to the condenser as noted prior to removal.
17. Remove the cap or tape from the compressor hose and the condenser.
18. Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the compressor hose and the condenser.
19. Lightly coat the new O-ring seal (1) with mineral base 525 viscosity refrigerant oil.

IMPORTANT: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the O-ring seal to enter the refrigerant system.

20. Carefully slide the new O-ring seal (1) onto the compressor hose until seated.




21. Install the compressor hose to the condenser.
22. Orientate the compressor hose to the condenser as noted prior to removal.




23. Using a back-up wrench on the condenser fitting (2), secure the compressor hose fitting (1) to the condenser.

Tighten
Tighten the compressor hose fitting to the condenser to 24 N.m (17 lb ft).

24. Lower the vehicle.
25. Install the battery heat shield.
26. Connect the negative battery cable.

Tighten
Tighten the negative battery cable bolt to 15 N.m (11 lb ft).

27. Program the transmitters. Refer to Transmitter Programming/Synchronization in Keyless Entry.
28. Evacuate and charge the refrigerant system. Refer to Refrigerant Recovery and Recharging.Service and Repair
29. Check the compressor hose to accumulator, compressor and condenser joints for leaks. Refer to Leak Testing.Leak Testing
