To check drive belt for proper operation, with engine running, check drive belt tracking (position of drive belt
on one of the grooveless pulleys, idlers or drive belt tensioner). If edge of drive belt rides beyond edge of
pulley, noise and premature wear may result. If a drive belt tracking condition exists, visually check drive belt
tensioner for damage, especially mounting pad surface. If drive belt tensioner is not installed correctly with
locating pins in locating holes, mounting surface pad will be out of position. This will result in abnormal drive
belt tension and chirp and squeal noises.
If above procedures do not correct drive belt noise, try replacing drive belt with a known good drive belt.
However, drive belt noise may return, with mileage, if one of above conditions still exists uncorrected.
CAUTION: Incorrect drive belt installation will cause excessive drive belt wear and
may cause drive belt to come off drive pulleys.
NOTE: Replace belts if tensioner indicates belt is out of adjustment range. DO NOT
apply belt dressing to serpentine belt. Use illustration to help align serpentine
belt and to check belt routing and tension. See Fig. 15
through Fig. 17 .

With engine running, visually observe grooves in pulleys (not pulley flanges) for excessive wobble. Replace
components as required. Check all accessories, mounting brackets and drive belt tensioner, for any interference
that would prevent component from mounting properly. Correct any interference conditions and recheck belt
tracking. Tighten all accessories, mounting brackets and drive belt tensioner retaining hardware to specification.
Replace drive belt is excessive cracking or wear, severe glazing or frayed cords are present. Minor cracks in
back of drive belt are considered acceptable.
