Removal Procedure
- Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
- Disconnect the negative battery cable.
- For compression-style fittings; use a back-up wrench on the A/C refrigerant component (smaller size) fitting (2), then loosen the A/C refrigerant hose (larger size) fitting (1).
- For banjo-style fittings; remove the bolt retaining the A/C refrigerant hose to the A/C refrigerant component.
- Disconnect the A/C refrigerant hose from the A/C refrigerant component, discard the O-ring seal and cap or tape the A/C refrigerant hose and the A/C refrigerant component to prevent contamination.
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 A/C refrigerant hose and the A/C refrigerant component immediately.
Installation Procedure
- Remove the cap or tape from the A/C refrigerant hose and the A/C refrigerant component.
- Using a lint-free clean, dry cloth, carefully clean the sealing surfaces of the A/C refrigerant hose and the A/C refrigerant component.
- Lightly coat the new O-ring seal (1) with mineral base 525 viscosity refrigerant oil.
- For compression-style fittings; carefully slide the new O-ring seal (1) onto the A/C refrigerant hose until seated.
- For banjo-style fittings; carefully slide the new O-ring seal (1) onto the A/C refrigerant hose until seated.
- Install the A/C refrigerant hose to the A/C refrigerant component.
- For compression-style fittings; use a back-up wrench on the A/C refrigerant component (smaller size) fitting (2), then tighten the A/C refrigerant hose (larger size) fitting (1) to specification.
- For banjo-style fittings; install the bolt retaining the A/C refrigerant hose to the A/C refrigerant component, then tighten to specification.
- 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 A/C refrigerant hose(s) to the A/C component(s) joints for leaks. Refer to Leak Testing .
Important: DO NOT allow any of the mineral base 525 viscosity refrigerant oil on the new O-ring seal to enter the refrigerant system.
Leave a light coating of the refrigerant oil to remain on the A/C refrigerant 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 negative battery cable bolt to 15 N·m (11 lb ft).
