Gates 13-15 Mercedes-Benz GLK250 4-Cyl. 2.1L Diesel Tensioner Assy. Belt Drive Tensioner

This Gates belt tensioner assembly is built with a robust steel pulley and a strong spring mechanism, ensuring your accessory drive belt stays properly tensioned. For your 2013-2015 Mercedes-Benz GLK250 with the 2.1L diesel engine, a properly functioning tensioner is key to preventing belt slippage, which can cause issues like loss of power steering or alternator output.

Gates is a well-known name in belt systems, and this tensioner is designed to meet the specific needs of your diesel GLK250. It's a direct replacement part, meaning it fits right into the existing mounting location without needing modifications. This helps ensure that your engine's accessory drive components, like the alternator and water pump, continue to operate smoothly and efficiently.

When you're replacing your belt tensioner, it's often a good idea to inspect the condition of the drive belt itself. If the belt shows signs of cracking or wear, it should be replaced at the same time to avoid having to do the job twice.
