The serpentine belt is a long, winding belt that’s driven by your car’s engine. As the belt rotates, it transfers power from the engine’s crankshaft to the various components it powers using pulleys and a belt tensioner. Most belt tensioners have an internal spring and pulley system that keeps the serpentine belt tight and prevents issues like squealing, slipping, or overheating. Over time, the spring can become worn; when this happens, it won’t provide the pressure needed to keep the belt tight. Most manufacturers recommend replacing the serpentine belt at 90K miles, regardless of its condition to reduce the chances of it breaking. . To find specific recommendations for your vehicle, check your owner’s manual or ask your service advisor to look it up for you. The serpentine belt is vital for how your vehicle functions. Since it’s not an expensive part, it’s always best to be proactive and replace it before it fails.
