Signs of a Failing Serpentine Belt

If you’ve heard unusual sounds under the hood, it should cross your mind that it could be your serpentine belt. Your serpentine belt is one of the most important parts of your vehicle. It is a long and snake-like belt that goes through various systems with a network of pulleys. For instance, the serpentine belt powers the alternator, a/c compressor, water pump, power steering pump, and more.


With such a vital role in your car, it is important for you to keep an eye out for a worn serpentine belt. Read on to learn more about the red flags of serpentine belt failure. 

  • Physical wear and tear - Physical signs are the most obvious signs that indicate the belt is on its way out. Most of the time, your technician will inspect your belts and hoses at regular service intervals. Signs of cracks and tears indicate that it is time to replace it.
  • Loss of power - When the components that your serpentine runs through break down or malfunction, it is a sign that you should check your belt. Please have a professional technician check the belt to be sure.
  • Engine overheating - An overheating car can be attributed to various things, including a worn serpentine belt. Since the belt connects to the water pump, it shouldn’t be overlooked. A mechanic at Sherman Oaks Auto can inspect your cooling system and belt to be safe.

Most automakers will have a recommended time frame or mile mark where they recommend a serpentine belt replacement. To be on the safe side, you should follow their instructions to avoid the inconvenience of a breakdown and extensive damage.
