When Do I Need a Serpentine Belt Replacement?


The serpentine belt, also known as the alternator belt, is what helps to run your vehicle's accessories. The alternator itself makes sure that the battery stays charged while also keeping electrical components powered. The serpentine belt can be a v-belt or flat ribbed belt and can either just be running the alternator or can also be responsible for running the power steering pump, water pump, and A/C compressor.

If the serpentine belt is worn or tearing, it can be a cause for concern. The alternator won't be able to create the electricity it needs to, meaning you might lose power in your accessories and your vehicle altogether if the alternator isn't able to recharge the battery. Because the serpentine belt is made of rubber, it will age and wear out over time with regular use of your vehicle.

If your serpentine belt does need to be replaced, you may notice one or more of the following symptoms:

  • Interior lights appear dim

  • Battery warning light has turned on

  • Your engine stalls on the road

  • You hear a flapping noise of a broken belt under the hood

As soon as you recognize any of these warning signs, it is important to bring your vehicle into our shop for a thorough inspection. We can check to see if your serpentine belt does indeed need to be replaced, and if so, get that service done for you in a timely manner so that you can get back on the road.
