Thanks for the explanation on the starter motors (I hadn't thought about them having field windings instead of magnets) and the info on your electric fans. As I mentioned, most people over here only try electric fans as a last resort.

the elec fan that i have got is a universal type designed to reverse polarity.

rather than mount the elec fan directly the outside of the rad, i could mount it further away into the wheel arch to help draw away hot air.

nevertheless, i have removed the elece fan to try the mech fan only (have checked that it is mounted correclty also.

Try chucking away the thermostst and replacing it with a blanking sleeve, or drill a few holes in the thermostat.

This should improve things a bit.

Generally electric fans are "ducted" meaning that they have a close fitting shroud. They aren't nearly as effective at moving air if they aren't put up flush against the surface you're trying to move air through. If you move it off the inner wing with spacers, you'll probably recirculated a lot of that hot air rather than remove it.

DKs right, the further from the rad the fan is, the more pointless it is. You could try fitting the rubber shroud Rover used to use as a duct but it is best fitted hard up against the core.

My car is a clubman GT from AUS. It came with an extra radiator mounted in the front.





I took it out now the temperature rises when stationary never tried driving it yet without that extra radiator. Before I took it out it was fine. My 1098 mini never reaches half. Any suggestions? A stuck thermostat?

Parked? Or stationary?

What fan?

Yes I would check the thermostat.

On a fairly standard 1275 with a cooling system in good condition you do not need an electric fan at all.

 

But a normal mechanical fan is a MUST for the transverse engine in a Mini because the fan needs to run continuously and provide the correct throughput volume of air. An electric fan on its own will gain nothing and will not be good enough to cool the engine,

 

Simply fit the 11-blade fan (the correct way around), remove the electric fan and so long as the rest of the cooling system is in good order all will be well.

Hi On the road,

 

I have a fairly seriously souped up 1293 Mini I drove in Indonesia (hot weather!) for a year. Cooling system is stock standard (except alloy radiator) and the temperature gauge never got to halfway even in gridlocked traffic (normal in Bali!).

So, in my experience, a properly set up standard cooling system is all you need. Sort that out and toss the other stuff.

 

Cheers
