To replace a drive belt, also known as a serpentine belt, remove the old belt first by rotating the tensioner slowly. As the tensioner rotates, slide the belt off of the smooth pulleys, then as the tensioner fully releases, remove the old belt completely.Continue Reading
Using a belt placement tool, take the new belt and route it around the belt path. Rotate the tensioner again while loading the belt around it. Wrap the new belt around the pulley of the crankshaft, then around the pulleys with grooves. Finish by sliding the belt around any nongrooved roller. Make sure to check the belt, as it should be aligned with the pulleys and following the right path.
You can attach the drive belt using ordinary tools, but using a serpentine belt tool to loosen the tensioner and position the new belt makes the job much easier. In most cases, the belt can be replaced in about 15 minutes. This tool comes with a number of sockets, which fit almost any car, and the extension bars can be converted to different sizes and angles, allowing individuals to reach areas, such as the tensioner, which may be difficult to reach otherwise. A belt placement tool also helps to place the belt.Learn more about Car Parts & Maintenance
