NOTE:
- The A/C clutch air gap must be measured and adjusted, using the correct method, to make sure of 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.
