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. Refer to Battery Replacement in Engine Electrical.
3. Remove the battery heat shield. Refer to Battery Heat Shield Replacement in Engine Electrical.



4. Remove the nut retaining the heater pipe bracket to the cowl.
5. Reposition the heater pipe bracket to access the refrigerant lines.



6. Remove the compressor hose to accumulator retaining bolt.

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

7. Disconnect the compressor hose from the accumulator.
8. Remove and discard the O-ring.
9. Cap or tape the open compressor hose and the accumulator.
10. Reposition the compressor hose end.



11. Remove the accumulator bracket mounting nuts.

Important: Prior to removal, take note of the accumulator alignment to the accumulator hose and the rear evaporator tube.

12. Reposition the accumulator slightly to access the accumulator hose to accumulator fitting.
13. Cap or tape the open accumulator hose and the accumulator.



14. Using a back-up wrench on the accumulator fitting (2), loosen the accumulator hose fitting (1) from the accumulator.



15. Disconnect the accumulator hose from the accumulator.
16. Remove and discard the O-ring



17. Remove the accumulator from the vehicle.
18. Loosen the accumulator bracket clamp bolt.
19. Remove the accumulator from the accumulator bracket.
20. Inspect the accumulator bracket insulator and the accumulator lower insulator for wear or damage.



21. If replacing the accumulator, drain and measure as much of the oil as possible from the removed accumulator.

This measurement will be used during installation of the replacement accumulator.

1. Add the specified amount of PAG oil to the accumulator. Refer to Refrigerant System Capacities .
2. Replace the accumulator lower insulator, if necessary:




2.1.	Remove the paper backing from the lower insulator (1).

2.2.	Position and install the insulator (1) to the bottom of the accumulator (2) as shown.

3. Install the accumulator to the accumulator bracket.
4. Tighten the accumulator bracket clamp bolt just enough to provide some resistance in rotating the accumulator.
5. Install the accumulator and bracket to the vehicle.
6. Remove the cap or tape from the accumulator hose and the accumulator.
7. Install a new O-ring. Refer to O-Ring Replacement .



8. Install the accumulator hose to the accumulator.
9. Align the accumulator to the accumulator hose and the rear evaporator tube as noted prior to removal.




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.

10. Using a back-up wrench on the accumulator fitting (2), secure the accumulator hose fitting (1) to the accumulator.
