What It Does & How It Helps

The serpentine belt drives the water pump, alternator and accessories, and the spring-loaded tensioner keeps it at the correct tension. As the tensioner spring and pulley bearing wear, the belt slips, squeals and chirps, and a seized bearing or thrown belt can leave you stranded and overheating. A fresh belt and tensioner (or idler pulley) restore quiet, reliable accessory drive and steady coolant and charging output.
