SPECIAL TOOL(S)
NOTE:
-
The A/C clutch air gap must be measured and adjusted, using the correct method, to ensure correct A/C function. An A/C clutch air gap that is
greater than specifications may reduce A/C compressor performance or cause the A/C compressor to be inoperative, and may cause premature
wear of the A/C clutch disc and hub and A/C compressor pulley. An A/C clutch air gap that is less than specifications may cause the A/C
compressor to operate continuously, or may cause premature wear of the A/C clutch disc and hub and A/C compressor pulley.
-
It is not necessary to recover the refrigerant for A/C clutch air gap adjustment if the A/C compressor is not being removed from the vehicle.
1. Measure the A/C clutch air gap at three equally spaced places between the A/C clutch disc and the A/C compressor pulley.
-
If the clutch air gap is not within specification, proceed with adjustment.
2. Remove the A/C clutch disc and hub bolt.
