J 39400-A Halogen Leak Detector

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.



4. Disconnect the electrical connector from the A/C pressure switch.



5. Remove the A/C compressor hose nut at the compressor.
6. Disconnect the A/C compressor hose assembly from the compressor.



7. Remove the A/C compressor hose nut at the condenser.
8. Disconnect the A/C compressor hose assembly from the condenser.



9. Remove the A/C compressor hose nut at the accumulator.
10. Disconnect the A/C compressor hose from the accumulator.
11. Remove the A/C compressor hose from the vehicle.
12. Remove the A/C refrigerant pressure sensor from the hose.

1. Install the A/C refrigerant pressure sensor to the hose.
2. Install the A/C compressor hose to the vehicle.

Important: Inspect the seal washers for damage before reinstalling the A/C lines and hoses.

If any damage is noted during inspection, the suspect seal must be replaced.
Flat washer type seals do not require lubrication.




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.
