Gates DriveAlign Auto Tensioner Assembly

The Gates DriveAlign Automatic Belt Tensioner Assembly (also called a drive belt tensioner or serpentine belt tensioner) keeps the right tension on the accessory drive belt. It is designed to replace worn original tensioners and help the belt drive run quietly and reliably.

Key Features:

• Automatic spring-loaded design that keeps belt tension steady as the belt wears and as engine loads change
• Built as a complete assembly with the pulley and the tensioning mechanism together
• Precision-engineered to help keep the belt aligned, which reduces belt wear, noise and vibration
• Damping system controls belt movement and helps protect accessory components
• Quality construction intended to meet or exceed original equipment performance expectations
• Designed to work with the other parts of the accessory drive, including the belt, idlers and accessory pulleys

Gates is a well-known supplier of belts, hoses and drive system components to the automotive aftermarket and to original equipment manufacturers. A worn tensioner can cause belt squeal, belt slippage, premature belt failure and uneven accessory drive operation. Replacing the tensioner when you replace the belt is a common way to restore proper drive performance.
