Drive Belts, Mounts, Brackets and Accessories: Description and Operation

Accessory Drive

Component Locations:

This vehicle is equipped with:
^ a V-ribbed serpentine accessory drive belt.
^ an automatic drive belt tensioner.

New drive belts should be of the same type as originally installed.

Drive belt chirp is a regularly occurring chirping noise that occurs due to:
^ pulley misalignment.
^ excessive pulley runout.
^ worn out belt.
^ incorrect tension.

It can be a result of a damaged pulley or an incorrectly installed pulley that was not correctly aligned.

To correct drive belt chirp:
^ determine the area from where the noise comes.
^ check each of the pulleys in that area with a straightedge to the crankshaft pulley for front accessory drive.
^ look for the accessory pulley to be out of position in the fore/aft direction or at an angle to the straightedge.
^ inspect the drive belt.
^ inspect the belt tensioner.

Drive belt squeal is an intermittent noise that occurs when the drive belt slips on a pulley during certain conditions such as:
^ engine start-up.
^ rapid engine acceleration.
^ A/C clutch engagement.
