2003 FORD MUSTANG belt

Belt Tensioner, Automatic
Check the automatic drive belt tensioner:
1. With the engine off, check for correct drive belt routing; refer to Accessory Drive . Repair as
necessary.
2. Rotate the drive belt tensioner and check for a binding or frozen condition. Install new components as necessary.
Drive Belt Misalignment
CAUTION: Incorrect drive belt installation will cause excessive drive belt wear and may
cause the drive belt to come off the drive pulleys.
Non- standard drive belts may track differently or incorrectly. If a drive belt tracks incorrectly, install it
with an original equipment drive belt to avoid performance failure or loss of drive belt.
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. Make sure the (B) drive belt rides correctly
on the pulley. If a drive belt tracking condition exists, proceed with the following:
zVisually 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.
z With the engine running, visually observe the grooves in the pulleys (not the pulley flanges or
the pulley forward faces) for excessive wobble. Install new components as necessary.
z Check all accessories, mounting brackets and the drive belt tensioner for any interference that
would prevent the component from mounting correctly. Correct any interference condition and
recheck the drive belt tracking.
z Tighten all accessories, mounting brackets, and drive belt tensioner retaining hardware to
specification. Recheck the drive belt tracking. Klj . 3 ba
