Should I worry about a squeaky belt?

How long can I drive with squealing belts? Any unusual engine or vehicle noise is cause for concern and should be looked at soon after the noise is first noticed.

What can I put on a squeaky belt?

Spray just enough WD-40 onto the belt to lightly cover the area where the squeal occurs. Short, sharp blasts work best to ensure the belt is not saturated. Oversaturating the belt will result in severe slipping, which can permanently damage the belt.

Why is my belt squealing when I accelerate?

The serpentine belt can be a common cause. If the belt is worn (dry, cracked,glazed) it can slip on acceleration and make a squealing sound. Also, if any of the pulleys on the alternator, p/s pump,etc, are worn or loose, they can cause the belt to squeal.

Do new timing belts squeal?

Metal chains offer much better lifespans, and should last for the life of the engine in most cases. It should also be noted that timing belts do not squeak. The belt is toothed, so it doesn’t slip like a serpentine or V-belt. Any squeaking noise from around the timing belt cover must come from something else.
