How Long Does a Serpentine Belt Last?

Serpentine belt

How long does a serpentine belt last? Also known as the drive belt or accessory drive belt, the serpentine belt can last anywhere from 50,000 to 100,000 miles. It’s made from sturdy rubber. But like any rubber auto part, how long a serpentine belt lasts can be affected by heat exposure and friction in Waterford. The service department at Old Saybrook Hyundai is here to help you understand and know when to replace a serpentine belt. 

What Does a Serpentine Belt Do? 

Long ago the parts under your Madison car’s hood were connected by multiple belts. Now, they’re connected by a serpentine belt, named because of its long, winding snake-like appearance. It sends power to the alternator, power steering pump, water pump, and air conditioning system. 

When to Replace a Serpentine Belt 

How long does a serpentine belt last? As mentioned, you can get a lot of miles in Branford from a serpentine belt. But over time the rubber will begin to wear, peel, crack, slip, or fray. Here are the signs that tell you when to replace a serpentine belt: 

  • Squealing Noises: You’ll hear this if your serpentine belt is stretching or the tension is low, or if the belt and pulley aren’t properly connected. 
  • Wear and Tear: A visual check will tell you when to replace a serpentine belt when you see cracks, uneven wear, etc. on the belt. 
  • Systems Failure: If the power steering and/or air conditioning fail, it could be a sign that it’s time to replace the belt. 
  • Complete Breakdown: This dangerous situation can happen if you ignore the previously-mentioned signs that it’s time to replace your serpentine belt. Stay safe by keeping a close eye on the belt as your vehicle ages. 

What is a Belt Tensioner? 

Modern drive belts feature self-controlled belt tensioners. A spring and pulley system holds the correct amount of tension in the serpentine belt to prevent damage and breakage while keeping it working properly. It also keeps your belt in place so you aren’t as likely to have a slipped belt that causes a loss of power to your power steering, cooling system, or engine. It’s a good idea to have the belt tensioner replaced when you replace your serpentine belt.
