Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Accessory Drive
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.
