When compared to other components in your car, belts and hoses
have one of the shortest life spans. These items are constantly exposed to engine heat, vehicle vibrations, and harmful chemicals, which all have the potential to cause cracks and leaks. Some symptoms to be aware of for belts and hoses nearing failure include squeaking, screeching, or grinding noises that begin when starting your engine or appear during vehicle operation. It's worth noting that grinding sounds near belts are usually associated with a bad pulley bearing rather than the belt itself, as the pulley bearing may freeze up and ultimately lead to a belt replacement.
