thanks for the info, got the alternator belt done the same time as the power steering belt a few month ago, been told my van needs two belts for the timing, so i have been given a price for water pump and the two belts, now i just need to order the m18 stretch bolt, new tensioner with bolt and a vibration damper pulley, gonna cost more than i thoughtA new M18 stretch bolt for the damper pulley. About a tenner of VW. I think thats what your thinking off.
Also new tensioner and bolt, water pump and gasket and the belt itself.
Also a good time to replace the alternator belt and vibration damper pulley if there not going to last until the next TB change.
