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, cause the A/C compressor to be inoperative or 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 cause premature wear of the A/C clutch disc and hub and A/C compressor pulley.
  1. Remove the A/C compressor. For additional information, refer to CLIMATE CONTROL article.
  2. Install the runout gauge set.
    1. Clamp the runout gauge set on the compressor-mounting boss.
    2. Position the runout gauge set to contact the disc portion of the A/C clutch disc and hub assembly, and tighten the flex-arm.
