Accessory Drive
WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
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.
