While replacing my waterpump on my car I noticed that as well the fan on the radiator there an electric fan built in the wing which is controlled by a thermos switch at the bottom of the radiator. My question is why have 2 can the one that permanently turns when the engine on could that be removed and just rely on the the electric fan

I don't think the electric fan can keep it cool by itself. It would also have to have a good seal to the radiator so it doesn't pull air around it.

The electric one is not as close to the engine to get the air from around it. It is also noisier. I switch on my electric occasionally in hard accelerations, city driving, etc.

I did toy with having an electric fan only, but having spoke to various people on the mini forum deemed best way was to have a secondary fan, (like yours), as mine did,nt originally. The only option really for 1 x electric fan, would be to have a Kenlowe type fan strapped to the radiator, the only way to get enough air flow without (lost) flow. The main advantage would be quicker warm up.

I tried an electric fan only. It seemed to get in the way at cruising speeds. Ran nice and cool at low speeds.

Thanks for your advice . Now if I fitted a kenlowe the switch at the bottom of the the radiator works between 88 and 96 degree C would that be effective enough to keep the car at its optimum running temperature or do do you think it would be better to put a separate thermal switch

Me personally, if it was a back-up fan, to work with the existing fan then wire to the rad switch, but if your running just an electric fan , then have it on an adjustable thermo-switch so you can then set precisely. Just my opinion.
