Installation Notes and Tips

Verify OE number 6512001770 and compare the listed dimensions before installation. Inspect the accessory drive belt, idler pulleys, and adjacent components for wear at the same time, since a worn belt system can shorten the service life of the new tensioner. Confirm the vehicle application carefully for 2013-2015 Mercedes-Benz GLK250, 2015 Mercedes-Benz ML250, and 2016 Mercedes-Benz GLE300d.
