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



2. Remove the condenser tube and evaporator hose from the thermal expansion valve (TXV).
3. Remove and discard the seal washers.



4. Remove the TXV bolts.
5. Remove the TXV.
6. Remove and discard the seal washers.

1. Install new seal washers to the evaporator core fittings. Refer to Sealing Washer 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.

3. Install the TXV bolts.

Tighten
Tighten the bolts to 7 N·m (62 lb in).




4. Install new sealing washers on the condenser tube and evaporator hose fittings. Refer to Sealing Washer Replacement .
5. Install the condenser tube and evaporator hose to the TXV.
6. Install the TXV nut.

Tighten
Tighten the nut to 20 N·m (15 lb ft).
