Air Conditioning Accumulator Replacement 2.2L Engine

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.

1. Disconnect the negative battery cable.
2. Recover the refrigerant from the system. Refer to Refrigerant Recovery and Recharging .
3. Remove the compressor and condenser hose assembly from the accumulator. Refer to Compressor Hose Assembly Replacement .



4. Remove the evaporator and accumulator hose assembly from the accumulator. Refer to Evaporator and Accumulator Hose Assembly .



5. Remove the accumulator clamp bolt.
6. Remove the accumulator from the evaporator.



7. Remove the accumulator from the accumulator clamp.

1. Install the accumulator into the accumulator clamp.
2. Install the accumulator to the evaporator.




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.

3. Install the accumulator clamp bolt.

Tighten
Tighten the bolt to 10 N·m (88 lb in).




4. Install the evaporator and accumulator hose assembly to the accumulator. Refer to Evaporator and Accumulator Hose Assembly .
5. Install the compressor and condenser hose assembly to the accumulator. Refer to Compressor Hose Assembly Replacement .
6. Connect the negative battery cable.
7. Add refrigerant to the system.
8. Inspect the system for leaks.
