So I went to the scrapyard today and found a MK2 golf.......shell. I checked the MK3 but thats an entirely different pulley system, ribbed belt, not toothed. Then I saw a lonely looking Corrado sitting in the corner, popped the bonnet and there was a nice little 16v K-Jet engine in there, pulley system looked similar, so went about stealing it.
A lot of swearing and bodging and 2 hours later, yes 2 hours! I got the water pump pulley and the crank pulley off, but there is 1 issue. The water pump pulley was slightly damaged, there is two, the inner and outer. It looks like the inner pulley serves no real purpose and just spins freely and its the PAS belt that drives the water pump. As the inner pulley was damaged, I doubt I can stick with my original pulley, as the water pump will be driven by two different belts, not to mention it probably won't fit, so it looks like I'm back to square one!
I will test fit the components tommorow and see how it looks. Whats the risk of running the water pump off two different belts (if its even possible).
