Removal Procedure

    Object Number: 82082 Size: SH
  1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .

    2. 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.

  2. Disconnect the negative battery cable.
  3. Remove the battery heat shield. Refer to Battery Heat Shield Replacement in Body Front End.
  4. Remove the compressor hose to compressor retaining bolt.

    5. Important: Cap or tape the open compressor hose and the compressor immediately.

  5. Disconnect the compressor hose from the compressor, discard the seal washers and cap or tape the hose end and the compressor to prevent contamination.

Installation Procedure

    Object Number: 297220 Size: SH
  1. Remove the cap or tape from the compressor hose end (2) and the compressor (3).
  2. Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the compressor hose (2) and the compressor (3).
  3. Lightly coat the new seal washers (1) with mineral base 525 viscosity refrigerant oil.

    4. Important: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the seal washers to enter the refrigerant system.

  4. Carefully slide the new seal washers (1) onto the compressor hose (2) until seated.

    5. Object Number: 82082 Size: SH
  5. Install the compressor hose to the compressor.
  6. Install the compressor hose to compressor retaining bolt.

    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.

    Important: After tightening the compressor hose (3) to the compressor (2), there should be a slight sealing washer gap (1) of approximately 1.2 mm (3/64 in) between the compressor hose (3) and the compressor (2).

  7. Tighten the compressor hose to compressor retaining bolt.

    8. Tighten
    Tighten the compressor hose to compressor retaining bolt to 26 N·m (19 lb ft).

  8. Connect the negative battery cable.

    9. Tighten
    Tighten the negative battery cable bolt to 15 N·m (11 lb ft).

  9. Install the battery heat shield. Refer to Battery Heat Shield Replacement in Body Front End.
  10. Program the transmitters. Refer to Transmitter Programming/Synchronization in Keyless Entry.
  11. Evacuate and charge the refrigerant system. Refer to Refrigerant Recovery and Recharging .
  12. Check the compressor hose to compressor joint for leaks. Refer to Leak Testing .
