When you're replacing your serpentine belt system, you'll want to make sure all the pulleys are in good shape. This Gates DriveAlign Idler Pulley is a direct replacement part designed to keep your belt running true. It's made from a tough thermoplastic material that holds up well to the heat and stress of the engine bay. This particular pulley has a 90mm outer diameter and is designed for a 25.5mm belt width, fitting a wide variety of vehicles from the late 80s through the mid-2000s, including many Buick, Chevrolet, and Ford models.

Gates has been a well-known name in belts and related components for a long time, and this pulley is built to meet those standards. The DriveAlign technology means it's made to be a precise fit, helping to ensure proper belt tension and alignment. This is important because a misaligned or worn idler pulley can cause premature belt wear or noise. Replacing it along with your belt is a good practice to get the most life out of your new belt and keep your engine running smoothly.
