When to Replace a Serpentine Belt

Many of our Seward drivers ask us, “How long does a serpentine belt last?” or when to replace a serpentine belt. At Sid Dillon Chevrolet Crete in Crete, we have the answers you seek! Serpentine belts, which are drive/accessory belts, are made of rubber, so they will last 50,000 to 100,000 miles. If they’re constantly exposed to friction or heat, they can deteriorate and break over time. If you need to visit our service center for replacement, schedule a service appointment today!

What is a Serpentine Belt?

Before you learn when to replace a serpentine belt, you’ll need to know what a serpentine belt is and what it does. The serpentine belt is a long, winding belt that delivers power to the alternator, power steering pump, air conditioning system, and water pump. Your serpentine belt must be in good condition to deliver an effective amount of power to your other systems as you cruise through Milford.

When is it Time to Replace a Serpentine Belt?

As you continue to drive your vehicle around Milford and beyond, time can take a toll on the belt. It can start to slip, crack, peel, or fray. You’ll know when to replace a serpentine belt with these flags:

• Squealing Noises: Any strange noises can mean belt stretching or low tension. The pulley or the belt could be connected incorrectly.
• Wear and Tear: Some signs are uneven wear, cracks, fray, and more on the belt.
• Systems Failure: If your air conditioning or power steering systems fail, you need to replace your belt immediately.
• Complete Breakdown: A complete belt failure looks like a total breakdown. This can be extremely dangerous for yourself and fellow drivers through Crete.

What is a Belt Tensioner?

A belt tensioner is a modern version of the belt with self-controlled tensioners. It uses an internal spring and pulley system to hold a set amount of tension on the serpentine belt to prevent any future breakage or damage. Belt tensioners help ensure the belt stays in place because loose belts can lead to the engine, cooling system, or power steering system shutting off.
