Removal Procedure
- Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
- Disconnect the negative battery cable.
- Remove the battery. Refer to Battery Replacement in Engine Electrical.
- Remove the battery heat shield. Refer to Battery Heat Shield Replacement in Body Front End.
- Remove the nut retaining the heater pipe bracket to the dash panel.
- Reposition the heater pipe bracket to access the refrigerant lines.
- Remove the compressor hose to accumulator retaining bolt.
- Disconnect the compressor hose from the accumulator, discard the O-ring seal and cap or tape the compressor hose and the accumulator to prevent contamination.
- Reposition the compressor hose end.
- Remove the accumulator bracket mounting nuts.
- Reposition the accumulator slightly to access the accumulator hose to accumulator fitting.
- Using a back-up wrench on the accumulator fitting (2), loosen the accumulator hose fitting (1) from the accumulator.
- Disconnect the accumulator hose from the accumulator, discard the O-ring seal and cap or tape the accumulator hose and the accumulator to prevent contamination.
- Remove the accumulator from the vehicle.
- Loosen the accumulator bracket bolt.
- Remove the accumulator from the accumulator bracket.
- Inspect the accumulator bracket insulator and the accumulator lower insulator for wear or damage.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
Important: Cap or tape the open compressor hose and the accumulator immediately.
Important: Prior to removal, take note of the accumulator orientation to the accumulator hose and the evaporator tube - rear.
Important: Cap or tape the open accumulator hose and the accumulator immediately.
Installation Procedure
- Replace the accumulator bracket insulator, if necessary.
- Replace the accumulator lower insulator, if necessary:
- Install the accumulator to the accumulator bracket.
- Tighten the accumulator bracket bolt just enough to provide some resistance in rotating the accumulator.
- Install the accumulator and bracket into position in the vehicle.
- Remove the cap or tape from the accumulator hose and the accumulator.
- Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the accumulator hose and the accumulator.
- Lightly coat the new O-ring seal (1) with mineral base 525 viscosity refrigerant oil.
- Carefully slide the new O-ring seal (1) onto the accumulator hose until seated.
- Install the accumulator hose to the accumulator.
- Orientate the accumulator to the accumulator hose and the evaporator tube - rear as noted prior to removal.
- Using a back-up wrench on the accumulator fitting (2), secure the accumulator hose fitting (1) to the accumulator.
- Install the accumulator and bracket into position.
- Install the accumulator bracket mounting nuts.
- Tighten the accumulator bracket bolt.
- Remove the cap or tape from the compressor hose and the accumulator.
- Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the compressor hose and the accumulator.
- Lightly coat the O-ring seal (1) with mineral base 525 viscosity refrigerant oil.
- Carefully slide the new O-ring seal (1) onto the compressor hose until seated.
- Install the compressor hose to the accumulator.
- Install the compressor hose to accumulator retaining bolt.
- Install the heater pipe bracket to the dash panel stud.
- Install the heater pipe bracket retaining nut.
- Install the battery heat shield. Refer to Battery Heat Shield Replacement in Body Front End.
- Install the battery. Refer to Battery Replacement in Engine Electrical.
- Connect the negative battery cable.
- Program the transmitters. Refer to Transmitter Programming/Synchronization in Keyless Entry.
- Evacuate and charge the refrigerant system. Refer to Refrigerant Recovery and Recharging .
- Check the accumulator joints for leaks. Refer to Leak Testing .
| 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. |
Important: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the O-ring seal to enter the refrigerant system.
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.
