Description
This is the roller that tensions the timing belt. Highly recommended to replace with every timing belt service. This is included in the ECS Timing Belt kit for TDI's
Has a squealing noise developed where your timing belt runs? Has your timing belt been thrown from your engine or snapped? The most likely culprit is a worn out timing belt tensioner.
Keeping tension on your timing belt is imperative for keeping everything turning properly. If some slop develops in your belt because of a poor tensioner, the timing set can skip a tooth, causing catastrophic damage and potentially ruining your engine. These replacement can keep everything tight.
The belt runs against this tensioner and keeps your belt firmly on the cam gears and crank. It makes sure the no teeth are missed and your engine is running with the correct timing.
