Serpentine Belt.

When to replace a serpentine belt

In Maintenance by Steves Auto Repair and Tire

The serpentine belt is a belt that goes around all of the engine accessories, including the power steering pump, air compressor and alternator.

Because the serpentine belt helps run these components, it’s important to have it checked regularly.

How often the serpentine belt should be changed

Manufacturers have recommendations for how often a vehicle’s belt should be replaced. 

Typically, they last about 100,000 miles, depending on the quality of the belt, the usage of the vehicle, and the environment that it’s in. 

You need to check not only the belt but the serpentine belt tensioner. Not enough pressure on the belt can cause it to wear, and the ribs can wear down on the belt and can actually start to slip.

Another factor is the serpentine belts can start to crack. If you start to get too many cracks per inch, then it’s definitely time to change the belt, no matter what the mileage is.

If you live near the ocean, where there’s a lot of salt in the air, the belts may only last 30,000 to 50,000 miles.
