Long shot but here goes...

I need a VW water pump pulley, ribbed belt type. I believe it was fitted to Golf Mk3 1.8 and 2.0 without aircon (early to late 1990's era). The VW part no. is 028 121 031K. Probably fitted to a host of other vehicles besides the Golfs.

some mk3's had cambelt driven water pumps, the diesels used that pulley, I believe the same pulley was used on the later powersteering pumps when they changed from v belt to multi v,

If you do a search for golf mk3 water pump, or golf mk3 power steering pump it should through one up.

Very dificult to get just the pulley, I have tried after a couple of unplanned off road excersions, as it hangs just out the bottom ot the undertray at curb height.

Your best bet is to get a complete pump assembly with pulley and sell the pump on, try searching under seat, skoda, audi as they share the pumps on some models.

Thanks bigbravedave. I have a power steering pulley but it's completely the wrong offset.
I'm trying to delete the power steering from a 1.8T whic has an external water pump. VW (in their wisdom) use a serpentine belt to drive the power steering pump which has a second v-pulley and belt to drive the water pump. If you bin the power steering you also bin drive to the water pump. I want to incorporate the water pump into the run of the serpentine belt and I reckon the pulley I'm after will have the correct offset (or near enough to space it if necessary).

No longer required because I've just ordered one from VW for £11.99 + VAT. What a pleasant surprise - not a bad price for a brand new genuine part!
