Is Your Serpentine Belt Trying to Tell You Something?

Is Your Serpentine Belt Trying to Tell You Something?

Let Weldon Spring Auto & Tire Help Keep Your Engine Running Smoothly

At Weldon Spring Auto & Tire, we know how important your serpentine belt is to the health of your vehicle. This hardworking belt powers essential systems like the alternator and air conditioning compressor—and in many vehicles, it also drives the power steering pump, power brake system, and even the radiator cooling fan.

While serpentine belts are built to last for thousands of miles, they don’t last forever. Over time, wear can cause the belt to slip, fray, or crack—and eventually, it could snap without warning. A failed serpentine belt can lead to serious engine trouble and leave you stranded.

That’s why we recommend regular inspections. Our technicians can spot signs of wear and let you know if it’s time for a replacement. Often, it’s smart to replace the belt tensioner at the same time. This spring-loaded pulley keeps the belt tight and running properly—if it fails, your belt won’t do its job.

Look out for these common warning signs:

  • A squealing noise when you accelerate

  • A slapping or flapping sound under the hood

  • Accessories like your AC or power steering acting up

If you’ve noticed any of these issues, don’t wait! Call Weldon Spring Auto & Tire today to schedule a quick inspection. We’ll check your serpentine belt, tensioner, and make sure everything under the hood is in great shape—so you can hit the road with confidence.
