When to Replace a Serpentine Belt

A serpentine belt is a vital component of your internal combustion engine that keeps various systems of your new or used vehicle running properly as you drive through New Castle. Unfortunately, it will wear out over time and need to be replaced. In our guide, we’ll go over when to replace a serpentine belt as part of regular car maintenance. Our service team will also answer the question, “How long does a serpentine belt last?”.

How Long Does a Serpentine Belt Last?

Serpentine belts (or drive belts/accessory drive belts) are made of sturdy rubber, so it’s not uncommon for them to last for 50,000 to 100,000 miles. However, exposure to heat and friction will wear them out eventually. When that happens, schedule an appointment at our service center near Indianapolis to replace a worn belt. Now we’ve answered, “How long does a serpentine belt last?” Next, we’ll explain what a serpentine belt does.

What Does a Serpentine Belt Do?

The drive belt is a long, winding belt that moves around a few key parts and powers some systems in your vehicle’s engine compartment. The serpentine belt makes the alternator, power steering pump, water pump, and air conditioning system work properly. The belt needs to be in good condition to effectively power these systems as your new vehicle moves through Yorktown.

When to Replace a Serpentine Belt

Over time, your vehicle’s serpentine belt will begin to peel, crack, slip, or fray. If you notice any of the following red flags, you’ll know when to replace a serpentine belt.

• Squealing Noises: Strange squealing noises indicate belt stretching or low tension, or the belt and pulley aren’t correctly connected.
• Wear and Tear: Signs of wear are tear are easily recognizable. You’ll see cracks, uneven wear, or thinning on the belt. We suggest you check the serpentine belt once a month.
• Systems Failure: If the power steering and air conditioning fail, your serpentine belt needs to be replaced immediately because the serpentine belt has completely failed. Steering your vehicle will be harder and your air conditioning won’t run cold.

What Is a Belt Tensioner?

A modern serpentine belt features a self-controlled belt tensioner. The tensioner uses an internal spring and pulley system to hold a specific amount of tension on the serpentine belt to prevent damage and breakage. Belt tensioners also help to keep the belt in place while it moves. Loose belts won’t run properly, and those same systems we mentioned earlier won’t run. Make sure you run the serpentine belt over the tensioner properly when you replace it.
