Removal Procedure
- Disconnect the negative battery cable.
- Recover the refrigerant from the system.
- Remove the evaporator nut from the accumulator.
- Remove the compressor hose assembly from the accumulator.
- Remove the O-ring seals.
- Cap or plug the open lines.
- Disconnect the electrical connectors from the accumulator.
- Remove the accumulator bracket screw.
- Remove the accumulator 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.
Refer to Refrigerant Recovery and Recharging .
Installation Procedure
- Install the accumulator to the vehicle.
- Install the accumulator bracket screw.
- Connect the electrical connectors to the accumulator.
- Install new O-ring seals.
- Install the compressor hose assembly to the accumulator.
- Install the accumulator to the evaporator.
- Connect the negative battery cable.
- Add refrigerant to the system.
- Inspect the system for leaks.
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 27 N·m (20 lb ft).
Tighten
Tighten the evaporator nut to 41 N·m (30 lb ft).
