You can cut the cost of replacing a serpentine belt in half by doing this job yourself! Your exact replacement cost is dependent on the type of vehicle you own, but most of the price of this job is in the labor. 

Keep in mind: Just about all engine drive belts are different, so make sure you have all of the proper information on hand when ordering a new belt. When in doubt, always refer to your owner’s manual.

What Is a Serpentine Belt?

The serpentine belt is a very important wear item on your car that can be easily overlooked.

The serpentine belt is how your engine sends mechanical power from the crankshaft to various components such as the alternator, air conditioning compressor, and power steering just to name a few. This flat, rubber belt is ribbed on one side and smooth on the other. 

Unlike older vehicles that used several belts, the serpentine belt allows engines to do this work with just a single belt. Most repair shops will recommend a serpentine belt replacement on mileage alone as preventive maintenance, but sometimes the belt shows signs of wear either through cracks, physical damage, or even a slick, glazed finish. You can learn more about other ways to tell if your serpentine belt needs to be replaced by reading this article.

What Happens If You Don’t Replace a Serpentine Belt?


A failed serpentine belt won’t lead to any check engine light issues, but it could cause severe engine damage if the belt is supposed to be connected to the water pump. This could cause the engine to overheat. Also, a broken serpentine belt will cause mechanical power steering systems to stop working, which could possibly cause an accident.


How Often Should You Replace a Serpentine Belt?

For exact manufacturer recommendations as to how often you should replace your serpentine belt, check your owner’s manual or the FIXD app for maintenance schedules. Most vehicles recommend a new serpentine belt every 50,000 to 100,000 miles. Learn the fundamentals of car maintenance by visiting our detailed guide here.
