Tools Required

J 39400-A Halogen Leak Detector

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Loosen the evaporator hose nut.



3. Disconnect the A/C evaporator hose (2) from the orifice valve.
4. Remove the evaporator hose nut.



5. Disconnect the A/C evaporator hose from the accumulator.



6. Remove the evaporator hose nut from the evaporator.
7. Remove the A/C evaporator hose from the evaporator.



8. Disconnect the electrical connector from the sensor.
9. Disconnect the surge tank hose from the surge tank.
10. Cap off the surge tank and line to prevent coolant leakage.
11. Pry up to remove the A/C line clip from the rail.
12. Remove the A/C evaporator hose from the vehicle.

1. Position the A/C evaporator hose in the vehicle.
2. Install the A/C evaporator hose clip to the rail.

Important: Inspect the seal washers for damage before reinstalling the A/C lines and hoses.

If any damage is noted during inspection, the suspect seal must be replaced.
Flat washer type seals do not require lubrication.



3. Install the A/C evaporator hose 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 line fastener.

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




5. Connect the electrical connector to the temperature sensor.



6. Install the evaporator hose to the accumulator.

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




7. Install the A/C evaporator hose (2) to the orifice solenoid.

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

8. Remove the caps the surge tank and hose.
9. Connect the surge tank hose to the surge tank.
10. Recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
11. Leak test the fittings of the component using the J 39400-A .
