Air Conditioning Compressor Hose Replacement 3.4L

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-3.4L.



3. Remove the A/C compressor hose nut from the A/C condenser.
4. Remove the A/C compressor hose from the A/C condenser.



5. Remove the A/C compressor hose nut from the accumulator.
6. Remove the A/C compressor hose from the accumulator.
7. Remove the lower air deflector. Refer to Radiator Air Lower Baffle and Deflector Replacement in Engine Cooling.




Important: Remove and discard all the used O-ring and sealing washers.

8. Remove the A/C compressor hose bolt from the A/C compressor.
9. Remove the A/C compressor hose from the A/C compressor.

1. Install new sealing washers onto the A/C compressor hose assembly. Refer to Sealing Washer Replacement .
2. Install the A/C compressor hose to the A/C compressor.




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.
