5. Remove the A/C compressor hose nut (2) and hose from the accumulator.
6. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
7. Remove the lower air deflector. Refer to Radiator Air Baffle Assemblies and Deflectors in Engine Cooling.



8. Remove the nut and the A/C compressor hose assembly at the A/C compressor.

Important: Remove and discard all the used O-ring and sealing washers.

9. Remove the A/C compressor hose assembly.

1. Install the A/C compressor hose assembly.

Important: The new O-ring seals must be lubricated with mineral base 525 viscosity refrigerant oil.

2. Install the new O-ring seal to the A/C compressor hose assembly. Refer to O-Ring Replacement .

3. Install the A/C compressor hose assembly to the rear of the A/C compressor.




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.
