Description
The belt tensioner on your Mercedes-Benz engine plays an import role in the belt drive system, and that role is keeping the accessory belt at a consistent tension to allow for proper operation of the belt driven accessories.
If your belt tensioner is showing symptoms of excessive wear, such as squealing from a slipping belt, a rattling sound from the tensioner mechanism or a grinding sound from a failing bearing, the tensioner needs to be replaced before it fails, and leads to failure of the belt itself.
If you are replacing your accessory belt tensioner, now would be a great time to inspect and replace other components in the belt drive system, such as the idler pulley or the belt, if they are starting to show signs of wear. Euromotiv carries a full line of belts, tensioners, pulley and the associated hardware you need to keep the belt drive system on your Mercedes-Benz functioning flawlessly.
