12. Disconnect the compressor electrical connector.
13. Disconnect the engine harness electrical connector.
14. Lower the vehicle.






15. Loosen the right hand engine mount strut, engine side.
16. Remove the right hand engine mount strut bracket brace bolts from the upper radiator support and rotate the strut and bracket rearward.
17. Remove the suction hose.
18. Remove and discard the sealing washers.
19. Cap or tape off the compressor suction port.

Installation Procedure

1. Install a new sealing washer onto the compressor end of the suction hose.
2. Install the suction hose.
3. Position the engine mount strut bracket flush with the upper radiator support.

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.
