Tools Required

J 39400-A Halogen Leak Detector

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement in Engine Controls - 3.1L or Air Cleaner Assembly Replacement in Engine Controls - 3.8L.



3. Loosen the suction hose nut (2) at the accumulator.
4. Disconnect the suction hose from the accumulator.



5. Remove the A/C compressor hose block fitting nut (1) from the accumulator.
6. Disconnect the A/C compressor hose from the accumulator.



7. Remove the accumulator bracket retaining bolt.



8. Remove the accumulator bracket bolt clamp.
9. Remove the accumulator from the mounting bracket.

1. Install the accumulator to the mounting bracket.




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.
