6. Release the drive belt tensioner.

Remove the drive belt from the compressor pulley.

7. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.



8. Remove the air baffle bolts.
9. Remove the air baffle.



10. Disconnect the electrical connector from the compressor.
11. Disconnect the engine harness electrical connector.

Reposition the engine harness away from the compressor.




12. Remove the suction hose to compressor nut.
13. Disconnect the suction hose from the compressor.
14. Remove and discard the sealing washer.
15. Cap or tape off the suction hose.



16. Remove compressor mounting bolts.
17. Lower the vehicle.
18. Remove the battery tray. Refer to Battery Tray Replacement in Engine Electrical.
19. Remove the lower radiator hose. Refer to Radiator Outlet Hose Replacement in Engine Cooling.
20. Disconnect the upper transmission oil cooler hose from the radiator. Refer to Automatic Transmission Oil Cooler Hose Replacement in Automatic Transaxle -- 4T65-E.
21. Remove the compressor.

Important: Replacement compressors are partially precharged with PAG oil. Refer to Refrigerant System Capacities .

22. If replacing the compressor, balance the compressor oil. Refer to Compressor Oil Balancing .

1. Install the compressor.
2. Connect the upper transmission oil cooler hose to the radiator. Refer to Automatic Transmission Oil Cooler Hose Replacement in Automatic Transaxle -- 4T65-E.
3. Install the lower radiator hose. Refer to Radiator Outlet Hose Replacement in Engine Cooling.
4. Install the battery tray. Refer to Battery Tray Replacement in Engine Electrical.
5. Raise the vehicle.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

6. Install the compressor mounting bolts.

Tighten
Tighten the bolts to 50 N·m (37 lb ft).




7. Remove cap or tape from the suction hose.

Important: Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the A/C refrigerant hoses and the A/C refrigerant component.

Flat washer type seals do not require lubrication.
8. Install a new sealing washer to the suction hose.
9. Connect the suction hose to the compressor.
10. Install the suction hose to compressor nut.

Tighten

11. Connect the electrical connector to the compressor.
12. Connect the engine harness electrical connector.
13. Install the air baffle.



14. Install the air baffle bolts.

Tighten
Tighten the bolts to 20 N·m (15 lb ft).

15. Lower the vehicle.



16. Release the drive belt tensioner.

Install the drive belt on to the compressor pulley.




17. Remove cap or tape from the discharge hose.
18. Install a new sealing washer to the discharge hose.
19. Connect the discharge hose to the compressor.
20. Install the discharge hose to compressor nut.

Tighten
Tighten the nut to 16 N·m (12 lb ft).

21. Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
22. Leak test the fittings of the component using J 39400-A .
