With the engine running, check drive belt tracking If the (A) edge of the drive belt rides beyond the edge of the pulleys, noise and premature wear may
occur. Ensure the (B) drive belt rides correctly on the pulley. If a drive belt tracking condition exists, proceed with the following:
Visually check the drive belt tensioner for damage, especially the mounting pad surface. If the drive belt tensioner is not installed correctly, the mounting
surface pad will be out of position. This will result in chirp and squeal noises.
^
With the engine running, visually observe the grooves in the pulleys (not the pulley flanges) for excessive wobble. Replace components as
required.
^
Check all accessories, mounting brackets and the drive belt tensioner for any interference that would prevent the component from mounting
properly. Correct any interference condition and recheck belt tracking.
^
Tighten all accessories, mounting brackets, and drive belt tensioner retaining hardware to specification. Recheck the drive belt tracking.
