Compressor Drive Belt
Inspect both pulleys and the idler for damage. If any component shows signs of cracks, chipping,
impact damage or any other signs of damage, replace the component.
If the damage indicates possible misalignment, check the pulley alignment. If the pulleys are not
properly aligned, check all fasteners for proper torque and that there are no loose or worn
components.
Note:
An automatic belt tensioner is being used; no manual tensioning of the belt is needed.
Replace the tensioner if it is showing signs of wear or damage.
