Tools Required

J 39400-A Halogen Leak Detector

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Remove the Powertrain Control Module (PCM). Refer to Powertrain Control Module Replacement in Engine Controls - 5.7L.
3. Remove the PCM mounting bracket and screws.
4. Remove the Thermal Expansion Valve (TXV) tube plate bolt (5).
5. Remove the tube retaining plate (7).
6. Remove the evaporator inlet tube (6) and compressor tube (4) from the TXV (10).
7. Remove and discard the O-rings (8).



8. Disconnect the evaporator tube (3) from the receiver dehydrator (6).
9. Remove and discard the O-ring (2).
10. Remove the evaporator tube from the retaining clips.
11. Remove the evaporator tube from the vehicle.

1. Install the evaporator tube to the retaining clips.
2. Install a new O-ring (2) onto the receiver dehydrator (6). 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.

3. Install the evaporator tube (3) to the receiver dehydrator.

Tighten
Tighten the nut to 11 N·m (97 lb in).




4. Install new O-rings (8) to the TXV (10). Refer to O-Ring Replacement .
5. Install the evaporator inlet tube (6) and the compressor tube (4) to the TXV.
6. Install the TXV tube plate (7) and bolt (5).

Tighten
Tighten the bolt to 10.5 N·m (93 lb in).

7. Install the PCM bracket. Secure the bracket with the screws.
8. Install the Powertrain Control Module (PCM). Refer to Powertrain Control Module Replacement in Engine Controls - 5.7L.
9. Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
10. Leak test the fittings of the component using J 39400-A .
