I replaced both the auxiliary and the steering pump belt on my '99 1.8 petrol engine today. Well at least I tried to...

After applying the correct tension to the auxiliary belt I tried to fasten the bolt that keeps the tension wheel itself in place. After just a few turns the bolt snapped. Normally not really a problem, except that this looks like a pretty special bolt.

I attached a picture of the broken bolt, would anyone know where to get a spare?

no you int

Can't see the picture but a LR dealership would be able to get hold of one. You also could find one in a breakers yard.
