Series 3 water pump with viscous fan

Hi all, need some help..... Have got a 75 series 3 2.25 diesel and the water pump is not working properly so ordered a new one which has come with a flat disc and 4 bolt holes in. The current one has a viscous fan on it so does anyone know if it is possible to get the viscous coupling of the old one and put it onto the new one and if so, how? Cheers

I think someone has retro fitted a 90td water pump,series would never have had a viscous unit

Series 3 diesel has a viscous fan water pump as an option. You need a different pump, part number ERC9200

I've got a working one going spare from a late 2.25d that I've removed if you're interested

Thanks guys for all u help. The part no. Is bang on the same water pump. Looks like I can source a new one about 6 miles down the road but thanks for the offer of spare one. Will email if I have no luck. Cheers again.
