When to Replace a Serpentine Belt

Service Center

How long does a serpentine belt last? Because serpentine belts (or drive belts/accessory drive belts) are produced using a strong, high-quality rubber, it is definitely possible that they will function properly for at least 50,000 to 100,000 miles. However, because they are exposed to heat and friction every time you drive, the serpentine belts will begin to wear down over time. If you need to replace your serpentine belt, you should set up an appointment at Don Franklin Auto. How do you know when to replace a serpentine belt? Don Franklin Auto has the details.

What Does a Serpentine Belt Do?

You may have heard the term serpentine belt, but what does it actually do? The drive belt is a long, winding belt that sends power to the alternator, power steering pump, water pump, and air conditioning system. If you want the serpentine belt in your car to power these essential systems as it should, you need to make sure it is in good condition. Below are a few warning signs that it is time for a new serpentine belt.

Signs You Need to Replace Your Serpentine Belt

As serpentine belts age, they start to slip, crack, peel, and fray. There are also a couple of warning signs that your serpentine belt needs to be replaced. Here are a few to look out for:

  • Squealing Noises: Strange noises indicate belt stretching or low tension, or the belt and pulley aren’t correctly connected.
  • Wear and Tear: You should be able to visibly see if the belt has begun to wear unevenly or if there are any cracks in the belt.
  • Systems Failure: You may need to replace the serpentine belt if the air conditioning or power steering in your car does not work.
  • Complete Breakdown: If the serpentine belt completely fails, it can cause your car to break down.

What is a Belt Tensioner?

Modern drive belts feature self-controlled belt tensioners. Using an internal spring and pulley system, they hold a specific amount of tension on the serpentine belt to prevent damage and breakage. Another purpose of a belt tensioner is to ensure that the belt stays in its proper position. This is important because if the belt is loose, your power steering, cooling system, and the engine will not function as they should. To help prevent mechanical failure, you will want to replace the belt tensioner at the same time the serpentine belt is replaced.
