1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Release the drive belt tensioner.
3. Remove the drive belt from the A/C compressor.
4. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
5. Remove the right front fender liner. Refer to Front Fender Liner Replacement in Body Front End.



6. Disconnect the electrical connection from the compressor.



7. Remove the A/C compressor hose assembly bolt from the compressor.
8. Remove the A/C compressor hose assembly from the compressor.
9. Remove and discard the seal washers.



10. Remove the compressor mounting bolts.
11. Remove the compressor and the spacer.
12. If replacing the compressor, refer to Compressor Oil Balancing .

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.
