I changed all pullies but with this belt is to big. contact local diler for VW cars nd asked for new (original altelnator and tensioner)
Other thing is to find shorter belt with same type of tooth. but would like to hv original part on car nd cos of that I need catalog No. cos for '91 year there are 2 catalog no. - don't know the difference btw them.
The toothed belt systems on the market aren't VW manufacture. There are a couple of different types on the market with slightly different tooth/belt profiles ( Pitstop Developements in the UK and RPM on the continent)so you will have to find out who made yours first.
A belt size of 1040x20x 8mm is a good place to start and should be available from anyone who sells belts.
The belt was made by Optimabelt
I compare original G40 belt with this one nd only differrence is this tooth belt is 2 mm thiner than original. But if y. calculate 2 mm with full size (1040 mm) of belt y'll get calculation that tooth belt is to long nd I can't tense belt enough cos my alternator is not original (it's slite to big). Problem is, now I hv to buy now tooth belt which is shorter for 0,5 cm.
For the first hand I managed to place original belts on tooth pulleys nd they fits. As I could see, lader changed sound when - it's louder nd hs got differend type of sound. This is normal or?
