8. Disconnect the engine wire harness from the field coil connector located on the top of the A/C compressor.
9. Disengage the engine wire harness from the wiring bracket located on the top of the A/C compressor.
10. Remove the four bolts that secure the A/C compressor to the mounting bracket and support the compressor.
11. Raise and support the vehicle.
12. Remove the underside compressor splash shield push pins and the splash shield.

14. If required, remove the four bolts that secure the compressor mounting bracket to the engine and remove the bracket.

INSTALLATION

NOTE:
- If a replacement A/C compressor is being installed, be certain to drain and measure the refrigerant oil contained in the old compressor. This will determine how much refrigerant oil the replacement A/C compressor must contain before it is installed.
- The receiver/drier should always be replaced when the A/C compressor is replaced. This will help remove any contaminants including moisture from the system.

1. If removed, position the compressor mounting bracket onto the engine and install the four retaining bolts. Tighten the bolts to 115 N.m (85 ft. lbs.).
2. Position the A/C compressor onto the compressor mounting bracket and support the compressor.
3. Install the underside compressor splash shield and the push-pin retainers.
4. Lower the vehicle.
5. Loosely install the four bolts that secure the A/C compressor to the compressor mounting bracket. Tighten each of the bolts using the following sequence to 33 N.m (25 ft. lbs.).
- The upper bolt at the front of the compressor.
- The lower bolt at the front of the compressor.
- The upper bolt at the rear of the compressor.
- The lower bolt at the rear of the compressor.
6. Engage the engine wire harness lead to the wiring bracket located on the top of the A/C compressor.
7. Connect the engine wire harness to the field coil connector.
8. Install the accessory drive belt.
9. Remove the plugs or tape from the refrigerant line fittings and the compressor ports.
10. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and a new gasket onto the suction and discharge line.
11. Connect the suction and discharge lines to the A/C compressor.
12. Install the nuts that secure the suction and discharge lines to the A/C compressor. Tighten the nuts to 23 N.m (17 ft. lbs.).
13. Install the radiator fan.
14. Connect the negative battery cable.
15. Evacuate the refrigerant system.
16. Charge the refrigerant system.
