Of the many auto repair issues that can affect your vehicle, those involving the engine can have the greatest impact on your safety and the ability to get from point A to B. While many drivers remember to get an oil change regularly, the serpentine belt is often overlooked. Here is a closer look at why caring for it is an auto repair essential.

What Does the Serpentine Belt Do?

The serpentine belt runs between several key engine components, ensuring that mechanical power from the engine is transferred to these areas. The parts powered by the serpentine belt include the alternator, air conditioning, power steering pump, and other vital components.

This single belt was designed to replace the individual belts that older cars used to power these systems. A single serpentine belt ensures consistent performance across all the components.

What Are Some Signs You Need to Replace It?

While serpentine belts have an expected life span of 60,000 to 100,000 miles, drivers should regularly inspect this part to avoid serious auto repair complications. A worn or cracked belt is more likely to suddenly snap while driving or cause serious damage to the systems it powers. Age and extreme heat exposure can accelerate serpentine belt deterioration.

In addition to signs of visual disrepair, drivers should listen for whining or squealing from the engine, which often occurs when a serpentine belt is near the end of its life span. The check engine light could also turn on because of a loose or damaged belt. It should be adjusted or replaced as needed.
