4 Reasons A Belt Will Squeal

Engine belts screech or squeal because the rubber belt slips on the metal pulley. Commonly, a slipping and squealing belt will result from one of 4 things.

Incorrect Installation

The belt must have enough tension when you are installing it. Additionally, it needs to be re-tensioned minutes after running the engine.

Leak

Water, leaking fluids, and other fluids coming from one part of the engine can contaminate the belt.

Misaligned Pulley And Tensioner

If you did not align the tensioner and pulley appropriately with the belt system, the rubber belt will slip and begin making unwanted noises.

Wear And Tear

As you use your vehicle, the belt runs without rest, which eventually causes it to lose its stiffness. Wear out can also cause the surface of the belt to become brittle, glazed, or cracked.

How To Fix A Squeaky Belt

Identify The Noise Source

The noise does not come from timing belts because they have teeth that prevent them from slipping. That said, you need to look at the other belts.

Dress The Belt

You can do this step by simply buying a belt dressing and putting. The dressing works by protecting and moisturizing the belt.

Tighten The Belt

A tensioner holds your belt in place. Find the tensioner and you should be able to loosen the bolt while holding it in place. This way, you will be able to move the bolt to put more tension on the belt.
