Insufficient A/C Cooling (Replace A/C Compressor and Condenser Hose Assm)

Some owners may comment on no A/C.

Loss of A/C refrigerant due to the A/C compressor and condenser hose assembly rubbing at the left rear area of the engine block, causing a hole.

A new A/C compressor and condenser hose assembly has been developed to correct this condition. The new hose allows for a tighter routing. Replace the A/C compressor and condenser hose assembly on affected vehicles. Use the following procedure and part number listed below.

1. Evacuate and recover the A/C system. Refer to the Refrigerant Recovery and Recharging procedure in the appropriate Service Manual.
2. Raise the vehicle. Refer to the General Information subsection of the Service Manual for information on lifting and jacking the vehicle.



3. To verify that the A/C compressor and condenser hose assembly is the cause of the condition, inspect the hose at the left rear engine block for signs of rub through. If no sign of rub through is present, refer to the Diagnosis section of the appropriate Service Manual.
4. Disconnect the A/C compressor and condenser hose assembly from the auxiliary evaporator line.



5. Remove the bolts that retain the clips on the A/C compressor and condenser hose assembly to the chassis.
6. Remove the nut from the stud that retains the A/C compressor and condenser hose assembly to the bell housing.
7. Lower the vehicle.
8. Remove the engine cover. Refer to the Engine Cover Replacement procedure in the appropriate Service Manual.
9. Remove the air cleaner. Refer to the Air Cleaner Assembly Replacement procedure in the appropriate Service Manual.
10. Remove the grille. Refer to the Grille Replacement procedure in the appropriate Service Manual.



11. Remove the nut (3) from the stud that retains the A/C compressor and condenser hose assembly to the intake manifold.

13. Disconnect the hose assembly from the condenser.
14. Disconnect the hose assembly from the accumulator.
15. Remove the A/C compressor and condenser hose assembly from the vehicle.
16. Install the A/C compressor and condenser hose assembly into the vehicle.
17. Connect the hose assembly to the accumulator.
18. Connect the hose assembly to the condenser.
19. Install the bolt (2) attaching the A/C compressor and condenser hose assembly to the compressor (5).



20. Install the nut (3) to the stud that retains the A/C compressor and condenser hose assembly to the intake manifold.
21. Install the grille. Refer to the Grille Replacement procedure in the appropriate Service Manual.
22. Install the air cleaner. Refer to the Air Cleaner Assembly Replacement procedure in the appropriate Service Manual.
23. Install the engine cover. Refer to the Engine Cover Replacement procedure in the appropriate Service Manual.
