23. Fully loosen the compressor mounting stud.
24. Reposition the A/C compressor forward.
25. Remove the compressor hose assembly from the vehicle.

1. Install the compressor hose assembly into position in the vehicle.
2. Install the compressor into position on the compressor mounting bracket.
3. Install the compressor mounting stud to the engine block.
4. Install the compressor upper mounting bolt.
5. Remove the cap or tape from the compressor hose assembly and the accumulator.
6. Install the new O-ring to the compressor hose assembly. Refer to O-Ring Replacement .



7. Connect the compressor hose to the accumulator.

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.
