J 39400-A Halogen Leak Detector

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .



2. Disconnect the A/C evaporator hose from the retaining clips.



3. Separate the A/C evaporator hose at the expansion tube location.



4. Remove the expansion tube from the line.

Important: Lubricate the new expansion tube O-ring with mineral base 525 viscosity refrigerant oil before installing into the evaporator hose.

Important: Ensure that the short screen and arrow face toward the evaporator.




1. Install the new expansion tube.




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.

2. Connect the A/C evaporator tube.

Tighten
Tighten the O-ring joint connections to 27 N·m (20 lb ft).




3. Install the A/C evaporator hose into the retaining clips.
4. Recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
5. Leak test the fittings of the component using the J 39400-A .
