1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .



2. Remove the discharge hose mounting bolt (2) from the A/C compressor.
3. Remove the discharge hose (1) from the A/C compressor.
4. Remove the upper radiator baffle. Refer to Radiator Air Baffle Assemblies and Deflectors in Engine Cooling.



5. Remove the discharge hose nut from the condenser.
6. Remove the discharge hose from the condenser.
7. Disconnect the electrical connector from the A/C recirculation switch.
8. Remove the discharge hose from the vehicle.
9. Discard all of the used sealing washers. Cap the system openings.

1. Install the discharge hose (1) to the vehicle.
2. Connect the electrical connector to the A/C recirculation switch.



3. Install the discharge hose to the condenser using new sealing washers.

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.
