1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement in Engine Controls - 3.1L or Air Cleaner Assembly Replacement in Engine Controls - 3.8L.
3. Remove the vacuum brake booster. Refer to Power Vacuum Brake Booster Replacement in Hydraulic Brakes.
4. Remove the accumulator tube clip.
5. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
6. Remove the lower radiator air baffle. Refer to Radiator Air Baffle Assemblies and Deflectors in Engine Cooling.



7. Loosen the condenser tube nut at the condenser.
8. Disconnect the condenser tube from the condenser.
9. Lower the vehicle.
10. Disconnect the A/C refrigerant pressure sensor electrical connector.



11. Loosen the evaporator inlet tube nut.
12. Disconnect the evaporator tube from the condenser tube.

Important: Use care when removing the condenser tube.

13. Remove the condenser tube.
14. Remove and discard the O-ring.
15. Remove the A/C pressure sensor from the condenser tube.

1. Install the A/C pressure sensor to the condenser tube.

Important: Coat the new O-ring with mineral base 525 viscosity refrigerant oil.

2. Install the new O-ring onto the condenser tube. Refer to O-Ring Replacement .
3. Install the condenser tube into place.
4. Connect the evaporator inlet tube to the condenser tube.




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.

5. Tighten the evaporator inlet tube nut.
