## Air Conditioning Compressor Replacement 3.4L

### Removal Procedure

Important: When replacing a failed compressor it will be necessary to inspect the expansion orifice tube for material build up. Clean or replace as necessary. Refer to Expansion (Orifice) Tube Replacement .

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Remove the drive belt. Refer Drive Belt Replacement Engine Mechanical - 3.4L.
3. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
4. Remove the right front wheelhouse splash shield. Refer to Wheelhouse Splash Shield Replacement in Body Front End.
5. Disconnect the electrical connection at the compressor.
6. Remove the compressor/condenser hose from the compressor.
7. Remove and discard the seal washers.
8. Remove the three compressor attaching bolts.
9. Remove the compressor and the spacer.

### Installation Procedure

Important: When servicing or replacing the compressor, drain and measure the oil from the compressor.

1. Drain the compressor oil from the new compressor.
2. Refill the compressor with the same amount of oil that was drained from the old compressor.

If less than 60 ml (1 oz) was drained from the old compressor, add 60 ml (2 oz).

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.

3. Install the bolts and the spacer to the compressor.
4. Install the bolts, the spacer, and the compressor to the engine.

2. Tighten the front rear bolt to 50 N·m (37 lb ft).
3. Tighten the bottom bolt to 50 N·m (37 lb ft).

5. Install NEW seal washers to the compressor ports.
6. Install the compressor/condenser hose and the bolt to the compressor.
