Tools Required

J 39400-A Halogen Leak Detector

1. Recover the refrigerant from the A/C system. Refer to Refrigerant Recovery and Recharging .
2. Remove the battery heat shield. Refer to Battery Heat Shield Replacement in Engine Electrical.
3. Remove the upper radiator support. Refer to Radiator Support Replacement in Engine Cooling.



4. Disconnect the electrical connector from the refrigerant pressure sensor.



5. Remove the bolt which secures the front evaporator tube to the condenser.

Important: Cap or tape the open A/C components immediately to prevent system contamination.

6. Disconnect the front evaporator tube from the condenser.
7. Remove and discard the O-ring.
8. Cap or tape the open front evaporator tube and the condenser.



9. Remove the bolt which secures the front evaporator tube to the rear evaporator tube.
10. Disconnect the front evaporator tube from the rear evaporator tube.
11. Remove and discard the O-ring.
12. Cap or tape the front and rear evaporator tubes.



13. Remove the front evaporator tube from the vehicle.
14. Remove the A/C refrigerant pressure sensor from the evaporator tube.
15. Discard the O-ring.

1. Install a new O-ring onto the A/C refrigerant pressure sensor. Refer to O-Ring Replacement .

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.

2. Install the A/C refrigerant pressure sensor to the evaporator tube.

Tighten
Tighten the sensor to 4.75 N·m (42 lb in).

3. Remove the cap or tape from the evaporator tubes.
4. Install new O-rings onto the front and rear evaporator tubes. Refer to O-Ring Replacement .



5. Install the front evaporator tube to the vehicle.



6. Connect the front evaporator tube to the rear evaporator tube.
7. Install the bolt which secures the front evaporator tube to the rear evaporator tube.

Tighten
Tighten the bolt to 25 N·m (18 lb ft).

8. Remove the cap or tape from the condenser.



9. Connect the front evaporator tube to the condenser.
10. Install the bolt which secures the front evaporator tube to the condenser.

Tighten
Tighten the bolt to 27 N·m (20 lb ft).




11. Connect the electrical connector to the refrigerant pressure sensor.
12. Install the upper radiator support. Refer to Radiator Support Replacement in Engine Cooling.
13. Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
14. Install the battery heat shield. Refer to Battery Heat Shield Replacement in Engine Electrical.
15. Leak test the fittings of the component using J 39400-A .
