3. Disconnect the evaporator hose assembly (2) from the hold down (1) on the right lower frame rail.
4. Disconnect the low temperature sensor electrical connector.
5. Remove the evaporator hose nut (1).



6. Disconnect the evaporator hose assembly (2) from the evaporator core.
7. Remove the upper filler panel. Refer to Filler Panel Replacement - Upper in Body Front End.



8. Remove the nut (1) retaining the evaporator hose assembly (3) to the condenser.
9. Disconnect the evaporator hose assembly (3) from the condenser.
10. Remove the evaporator hose assembly.

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.

Important: Inspect the seal washers for damage.
