Why does my timing belt squeal when I start it?
Over time, wear and tear can take a toll on the belt and the pulleys, which often results in that high-pitched chirping sounds when you start the car and accelerate. A worn belt can, therefore, begin to slip, which is one of the causes the squeal. Alternatively, cracks can cause the belt to snap.

Why does my car belt make a squeaking sound?
Car Engine Belt Sound The sound of a squeaking belt in a car’s engine can be caused by weather conditions, leaking fluids, maintenance issues or wear and tear. The magnitude of sound can range from a soft squeak to a loud and noisy squeal and it may occur while starting a cold engine or during normal vehicle operation.
How can I tell which belt is making the noise?
To determine which belt is making the noise, the best practice is to ask an assistant to start the engine while taking a look under the hood. Modern vehicles typically have one or two belts: A single serpentine belt that drives several components or a separate one for the alternator. Older vehicles may have a series of belts.
Why does my pulley belt squeal in warm weather?
It can also be checked for tension by pushing down on it. Loose belts are more likely to squeal in warm weather. However, if the belt appears to be tight and in good shape, then the issue may be the internal bearings of the pulley. The same visual and tension check can be performed on the serpentine belt.

Why does my alternator make a squeaking noise?
It is generally easier to determine when alternators are the cause of the squeak since they tend to be closer to the top and front end of the engine. After turning off the engine, the belt can be visually inspected for wear and tear. It can also be checked for tension by pushing down on it. Loose belts are more likely to squeal in warm weather.
