Electric fans

[Charles P]

Thanks so far!
I am running 12 volts.
Mike's point is interesting!
Do many people run standard Austin radiator cores and fans successfully in situations similar to mine?
If so which type of core? Does a standard fan use much power - It was suggested to me that a fan uses at least 5% of engine power.
Reverting back does have attractions!
Steve - why did you use a modern core?

And Charles - what fan do you use?
My fan is also only manually switched and is never needed on the road.

I cheap one.  Might have been from Car Builder Solutions or EBay. It's about 7 or 8 inches. I'll look tomorrow and see if there's any marking
