Removal Procedure
- Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
- Disconnect the negative battery cable.
- Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
- Using a back-up wrench on the condenser fitting (2), loosen the compressor hose fitting (1) from the condenser.
- Disconnect the compressor hose from the condenser, discard the O-ring seal and cap or tape the compressor hose and the condenser to prevent contamination.
- Lower the vehicle; leave the vehicle on the hoist.
- Remove the battery heat shield. Refer to Battery Heat Shield Replacement in Body Front End.
- Remove the compressor hose to compressor retaining bolt.
- Disconnect the compressor hose from the compressor, discard the seal washers and cap or tape the hose end and the compressor to prevent contamination.
- 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.
- Remove the compressor hose from the vehicle.
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: Prior to removal, take note of the compressor hose routing and orientation between the compressor and condenser.
Important: Cap or tape the open compressor hose and the condenser immediately.
Important: Cap or tape the open compressor hose and the compressor immediately.
Important: Cap or tape the open compressor hose and the accumulator immediately.
Installation Procedure
- Install the compressor hose into position in the vehicle.
- 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.
- Remove the cap or tape from the compressor hose end (2) and the compressor (3).
- Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the compressor hose (2) and the compressor (3).
- Lightly coat the new seal washers (1) with mineral base 525 viscosity refrigerant oil.
- Carefully slide the new seal washers (1) onto the compressor hose (2) until seated.
- Install the compressor hose to the compressor.
- Install the compressor hose to compressor retaining bolt.
- Tighten the compressor hose to compressor retaining bolt.
- Raise the vehicle.
- Route the compressor hose to the condenser as noted prior to removal.
- Remove the cap or tape from the compressor hose and the condenser.
- Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the compressor hose and the condenser.
- 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 compressor hose until seated.
- Install the compressor hose to the condenser.
- Orientate the compressor hose to the condenser as noted prior to removal.
- Using a back-up wrench on the condenser fitting (2), secure the compressor hose fitting (1) to the condenser.
- Lower the vehicle.
- Install the battery heat shield. Refer to Battery Heat Shield Replacement in Body Front End.
- 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 compressor hose to accumulator, compressor and condenser joints for leaks. Refer to Leak Testing .
Important: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the O-ring seal to enter the refrigerant system.
Leave a light coating of the refrigerant oil to remain on the compressor hose in the area indicated (2) ONLY.
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.
Tighten
Tighten the compressor hose to accumulator retaining bolt to 20 N·m
(15 lb ft).
Important: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the seal washers to enter the refrigerant system.
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).
Tighten
Tighten the compressor hose to compressor retaining bolt to 26 N·m
(19 lb ft).
Important: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the O-ring seal to enter the refrigerant system.
Tighten
Tighten the compressor hose fitting to the condenser to 24 N·m
(17 lb ft).
Tighten
Tighten the negative battery cable bolt to 15 N·m (11 lb ft).
