Key benefits of using this tensioner include:

• maintaining the factory operating characteristics of the accessory drive system,
• reliable guidance of the water pump belt and reducing the risk of it slipping off,
• easier diagnostics and parts selection thanks to the presence of the OEM number and replacement numbers,
