Tools Required

J 39400-A Halogen Leak Detector

1. Recover the refrigerant from the A/C system. Refer to Refrigerant Recovery and Recharging .



2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
3. Remove the air baffle bolts.
4. Remove the air baffle.



5. Remove the suction hose to A/C compressor nut.

Important: Immediately cap or tape the open A/C components in order to prevent contamination.

6. Disconnect the suction hose from the A/C compressor.
7. Remove and discard the seal washer and position the suction hose aside.
8. Cap or tape the A/C compressor suction port and suction hose end fitting.
9. Lower the vehicle.



10. Remove the high pressure relief valve from the A/C compressor.

1. Lubricate the high pressure relief valve O-ring. Refer to O-Ring Replacement .

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.
