Car Engine Belt Making Noise: Causes and Solutions

Introduction

The car engine belt is a vital component that helps power the engine and other accessories. It is made of a durable material, but it can wear out over time or become damaged. When this happens, it can start to make noise.

Causes of Car Engine Belt Noise

There are several possible causes of car engine belt noise, including:

Worn belt: Over time, the car engine belt can wear out and become thinner. This can cause it to slip on the pulleys, which can create a squealing noise.
Loose belt: A loose belt can also cause noise. When the belt is loose, it can vibrate and make a slapping noise.
Damaged belt: A damaged belt can have cracks, tears, or other damage that can cause it to make noise. If the belt is severely damaged, it may break and cause the engine to overheat.
Misaligned pulleys: If the pulleys that the belt runs over are misaligned, it can cause the belt to rub against them and make noise.
Worn or damaged pulleys: Worn or damaged pulleys can also cause the belt to make noise. If the pulleys are not smooth, the belt can slip or vibrate, which can create noise.
