The accessory belt tensioner keeps your accessory drive belt tight on the engine's pulley system, to keep your accessories running at top performance. Over time, the tensioner can wear down, causing the belt to slip, or break completely. Another common concern is noise from the tensioner roller, due to the bearing inside the assembly being worn out, which can also cause the tensioner to break if left alone. Keep your accessories running correctly and replace your faulty tensioner today.
