New belt tensioner design from GATES for VAG 1.2, 1.6 and 2.0 TDI engines

It is no mistake when the belt tensioner in the timing belt kit - Triscan 8647 29096 - for VAG 1.2, 1.6 and 2.0 TDI engines does not quite look like the one that is to be replaced. Gates has chosen to introduce a belt tensioner that differs from that offered by Litens. The affected engines are mounted in 368 different car models, dating back to 2003 and up to today, and for that reason the following information is very relevant.

There are especially two changes that are important to be aware of when replacing the tensioner. First of all, the Gates belt tensioner does not have the retaining lug (see below) on the backside, which means that no special attention has to be paid to if the lug falls into place in the recess on the engine's surface. 

Secondly, the tension on the Gates tensioner is set differently to that of Litens by turning counter clock wise instead of clockwise (see photo below). Correct adjustment of belt tension is achieved for both belt tensioners in the same manner and tightening is always done with the torque specified by the manufacturer.
