For 1990-2009 cars

### Removal Procedure

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Disconnect the battery negative cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
3. Remove the compressor hose bolt.

Access through the top of the engine compartment.

4. Remove the intake air resonator. Refer to Intake Air Resonator Replacement in Engine Controls.
5. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
6. Remove the compressor hose O-rings.
7. Remove the compressor hose clamp to air pipe bracket bolt (1).
8. Remove the compressor hose bracket to oil pan bolt.
9. Remove the drive belt. Refer to Drive Belt Replacement in Engine Mechanical.
10. Remove the front compressor bolts.
11. Remove the rear compressor bolts (1).
12. Disconnect the compressor connector.
13. Lower the vehicle.
14. Remove the compressor through the top of the engine compartment.
15. If replacing the compressor, drain and measure as much of the oil as possible from the removed compressor:

15.1. | Drain the oil from both the suction and discharge ports of the removed compressor into a clean container.

15.2. | Remove the compressor crankcase oil drain bolt (1) and drain the crankcase oil from the removed compressor into the same container.

15.3. | Measure and record the amount of oil drained from the removed compressor.

This measurement will be used during installation of the replacement compressor.

### Installation Procedure

1. Replacement compressor will come without refrigerant oil. When adding oil to this compressor, adhere closely to the following instructions:

1.1. | If the amount of oil drained from the old compressor is less than or equal to 60 ml (2 oz), add 60 ml of new clean oil to the new compressor.

1.2. | If the amount of oil drained from the old compressor is greater than 60 ml (2 oz), add the same amount of new clean oil to the new compressor as drained from the old compressor.

2. Install the compressor through the top of the engine compartment.
3. Raise and suitably support the vehicle.
4. Install the rear compressor mounting bolts (1).
5. Install the front compressor mounting bolts.

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. Tighten the compressor mounting bolts.

Tighten
Tighten the compressor mounting bolts to 40 N·m (30 lb ft).

7. Install the drive belt. Refer to Drive Belt Replacement in Engine Mechanical.
8. Install the compressor hose bracket to oil pan bolt.

Tighten
Tighten the compressor hose bracket to oil pan bolt to 8 N·m (71 lb in).

9. Install the compressor hose clamp to air pipe bracket bolt (1).

Tighten
Tighten the compressor hose clamp to air pipe bolt to 8 N·m (71 lb in).

10. Install the compressor hose O-rings:

• | Use new O-rings.

• | Lubricate the new O-rings with mineral oil, 525 viscosity.

11. Install the compressor hose.
12. Install the compressor hose bolt.
13. Connect the compressor connector.
14. Lower the vehicle.
15. Tighten the compressor hose bolt.

Tighten
Tighten the compressor hose bolt to 33 N·m (24 lb ft).

16. Install the intake air resonator. Refer to Intake Air Resonator Replacement in Engine Controls.
17. Connect the battery negative cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
18. Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
19. Leak test the A/C system. Refer to Leak Testing .
