Air Conditioning Accumulator Replacement 2.2L

Tools Required

J 39400 Leak Detector

1. Recover the refrigerant from the system. Refer to Refrigerant Recovery and Recharging .
2. Remove the compressor suction hose assembly from the accumulator. Refer to Compressor Hose Assembly Replacement .
3. Remove the accumulator to evaporator retaining nut.



4. Remove the accumulator clamp bolt.
5. Remove the A/C low pressure switch.



6. Remove the accumulator from the accumulator clamp.

1. Install the accumulator into the accumulator clamp.
2. Install the A/C low pressure switch.




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 accumulator to evaporator retaining nut.

Tighten
Tighten the retaining nut to 16 N·m (12 lb ft).

5. Install the compressor suction hose assembly to the accumulator. Refer to Compressor Hose Assembly Replacement .
6. Evacuate and recharge the system. Refer to Refrigerant Recovery and Recharging .
7. Leak test the fitting(s) of the repaired or reinstalled components using the J 39400 .
