Tools Required

J 39400-A Halogen Leak Detector

1. Disconnect the refrigerant pressure sensor electrical connector.



2. Remove the pressure sensor (1) from the evaporator tube - front.
3. Remove and discard the O-ring seal from the sensor port on the evaporator tube - front.

1. Install a new 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.

2. Install the pressure sensor (1) to the evaporator tube - front.

Tighten
Tighten the sensor to 4.75 N·m (42 lb in).




3. Connect the pressure sensor electrical connector.
4. Leak test the fittings of the component using J 39400-A .
