20. Disconnect the auxiliary evaporator inlet tube from the evaporator inlet tube.
21. Cap or tape the auxiliary evaporator inlet tube.
22. Remove the evaporator outlet tube bracket bolt.
23. Disconnect the electrical connector on the evaporator outlet tube bracket.

Important: Gently lift up on the evaporator outlet tube bracket to allow enough clearance to slide the evaporator inlet tube underneath.




24. Remove the evaporator inlet tube.
25. Remove and discard the sealing washers and O-ring.

1. Install the new O-ring. Refer to O-Ring Replacement .
2. Install new sealing washers onto the evaporator inlet tube. Refer to Sealing Washer Replacement .

Important: Gently lift up on the evaporator outlet tube bracket to allow enough clearance to slide the evaporator inlet tube underneath.




3. Install the evaporator inlet tube.
4. Connect the electrical connector on the evaporator outlet tube bracket.

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.
