Have you ever heard a high-pitched squeal coming from your vehicle when you turn your vehicle or AC on? Chances are that noise is coming from your vehicle belt and it’s a sound you don’t want to ignore. Your vehicle belts are an important part of your car and need proper care in order to function properly. Let’s take a look at why vehicle belts squeal and what can be done to stop them.

What Are Vehicle Belts?

Vehicle belts are found in the engine compartment of most vehicles. They work as a direct connection between the engine crankshaft and other components. These include the alternator, water pump, air conditioning compressor, and more. All these parts rely on the vehicle belt for power transmission so they can operate properly.

Why Do Vehicle Belts Squeal?

When a belt starts to wear out or become too loose due to heat, it can cause it to slip off its pulley while running. This can result in a squealing noise. This noise indicates that the belt needs either tightening or replacing immediately. If left unchecked, this could cause further damage and result in costly repairs down the road.

For optimal belt performance, have a technician inspect them at every oil change. They should also check the belt's tension using a tension gauge. If it’s too loose, the technician can adjust it by tightening bolts to realign the belt. The technicians at Lou's Car Care inspect all belts during our Digital Vehicle Inspections. We check for cracks and signs of wear or tear. And we make recommendations for replacement before the belts fail completely.
