Tensioner Pulley

The accessory belt tensioner pulley on your Mercedes-Benz engine plays an important role in the belt drive system, and that role is allowing the belt tensioner to apply pressure to the belt as it travels along its path.

If your accessory belt tensioner pulley is starting to show signs of excessive wear, such as wobbling, grinding or squealing caused by a failing bearing, the pulley needs to be replaced before it fails and leads to failure of the belt itself.

If you are replacing your accessory belt tensioner pulley, now would be a great time to inspect and replace other components in the belt drive system, such as the tensioner or the belt if they are showing signs of wear.
