Tools Required

J 39400-A Halogen Leak Detector

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Remove the evaporator hose bolt from the condenser.
3. Remove the evaporator hose from the condenser.



4. Remove the evaporator hose nut from the evaporator.



5. Remove the evaporator hose and the accumulator tube from the evaporator.



6. Remove the clip (1) retaining the evaporator hose to the frame rail.



7. Remove the evaporator hose from the vehicle.
8. Remove and discard the O-rings from the evaporator hose and the accumulator tube.

1. Install the new O-rings to the evaporator hose and the accumulator tube. Refer to O-Ring Replacement .
2. Position the evaporator hose in the vehicle.



3. Install the evaporator hose and the accumulator tube to the evaporator.




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.

4. Install the evaporator hose nut to the evaporator.

Tighten
Tighten the nut to 24 N·m (18 lb ft).





Important: If the clip was damaged during removal, install a new clip.

5. Install the evaporator hose into the clip (1) at the frame rail and fasten the clip.
6. Install the evaporator hose to the condenser.



7. Install the evaporator hose bolt to the condenser.

Tighten
Tighten the bolt to 24 N·m (18 lb ft).

8. Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
9. Leak test the fittings of the A/C component using the J 39400-A .
