Gates is known for making reliable engine components, and this DriveAlign Automatic Belt Tensioner is no exception. It's built to keep your accessory drive belt at the right tension, which is crucial for everything from your alternator to your power steering pump to work correctly.

This tensioner is designed to fit a wide range of vehicles, including popular models like the Chevrolet Colorado and GMC Canyon, as well as the GMC Envoy and Hummer H3. It's a direct replacement part, meaning it's made to install right where your old one came out, without needing any special modifications. Keeping your belt tensioner in good shape helps prevent premature belt wear and ensures your engine's accessories run smoothly.
