Regular car maintenance is an important part of warding off auto repairs. Your vehicle is made up of several intricate pieces, all designed to work together to run efficiently, including the serpentine belt. Here’s more about this lesser-known component of your car. 

What Is a Serpentine Belt?

The serpentine belt plays a crucial role in several different systems of your car, from the power steering pump to the alternator. This long, continuous belt is typically guided by an idler pulley or a belt tensioner and typically lasts between 50,000-100,000 miles. When exposed to regular heat and friction over the years, the belt can become worn down, cracked, or frayed.

What Does the Serpentine Belt Do?

The belt snakes around the important components of your car, connecting the alternator, air conditioning, water pump, and power steering to the aligning engine part. If the belt becomes worn or breaks, the coolant won’t be properly distributed throughout the vehicle, which could end up resulting in the need for auto repair.

What Are the Signs of a Failing Belt?

While an auto repair professional will inspect the serpentine belt during regular maintenance checks, it’s essential to recognize signs that it’s beginning to malfunction. One of the first indicators that your belt is beginning to crack is a squealing noise in the front of the vehicle, which is caused by a slippage or misalignment.

Another common symptom of a failing belt is if your power steering or AC isn’t working properly, or shuts down completely. These are serious issues that need to be evaluated by a mechanic to ensure that the vehicle doesn’t incur more extensive damage, like an overheating engine.
