Fan upgrade

[Sooner]

I have read all the threads, now totally confused. Just installed new old stock water pump, and want a simple fan upgrade. I have a good nine blade that is bold on, what and where do I get the part?
thanks

Which pump did you buy? The earlier one with the nose piece that holds fan with a single nut or the new style that has a spin on nut behind the fan?

I will have to check, it is out at my shop, bought many years ago as a spare, just like original I am replacing. Flat surface with 4 threaded 10mm holes
Thanks for the help

That pump holds the original friction clutch and five blade fan, or, the first gen viscous clutch mounted on a nose/extension which holds the clutch/fan with a mounting nut/bolt on the front of the fan.

you alrady have the parts but you could sell them here and
upgrade to the s34b36 water pump
and the adjoining fan
just a thought

So Alan, what does that even look like?

i think the m5 had a bolt pattern also

So I guess I am stuck with the five blade fan

I went on BavAuto and found an upgrade kit. Showed up and had the 9 blade fan, viscous clutch, and an adaptor.

Richard,

Item 6 on this page is the mount, still available, it works with your pump. It holds the viscous clutch so get the bolt as well.
