NOTE
If installing a new A/C compressor, the A/C clutch components should be reused unless obvious signs of damage are found.

    Do not use air tools. Damage to the A/C clutch field coil or A/C compressor may result.



    Inspect for physical damage, including cracked or melted components or discoloration due to excessive heat.
     
    Inspect for excessive wear, including grooving in the A/C clutch disc and hub or A/C compressor pulley that is more than fingernail depth.
     
    Inspect for roughness in the A/C compressor pulley bearing.
