Hi, i appreciate that the fans on the MPI mini are a probelm area, but until now my one has been fine, but whilst given the Mini its regular run i checked the temp gauge and the engine was warming up more than normal. I checked under the bonnet and the fan was not kicking in. So i switched it all off checked a few things and found that the 15A fuse was blown, so i replaced it and started the car and the fuse blew again, and tried again with the same result. This car was all OK recently with everything working, and has had NO reapirs or changes/moodifications, but has been not used on the road (SORN), but i regularly run it and check it over and run it up and down a private road. I dont think its wiring related, any idea's?

Found out the problem, fan motor completely siezed!, can you buy the fan motor on its own or do you have to get the assembly at £140 ish - ouch !!!!!

Complete item im afraid, but have a look on ebay, there are similar fans for much less. Search for Spal

make sure you get one that blows, rather than sucks

How did you find that the fan had seized?
Just about to go out and check the fuses on mine, cant believe i didnt check somethign so simple by now. am frequently having trouble with fan not kicking at high temp. mostly in the queues to get into mini shows which can be a bit embarrassing :s

[maieth]

yep, its blowing fuses. 2 so far, i've run out now.
wish id checked that originally. whoops

okay, so how can i find out if it's the motor that's seized?

**EDIT** Fixed!
well, mostly. replaced thermostat and temperature sensor. fan finally comes on with engine now, shows no sign of turning off atm, but to be honest i dont care right now, id rather have it on all the time than off al the time

If something is siezed it doesnt normaly move. I would have thought tthat was the big give away

Hmmm,

Thought I'd tag along on this thread as I've also been having issues with the fan not kicking in - causing steam to riiiiiise from the engine bay.
I noticed that the B9 fuse has been blowing a lot recently so have stocked up on these while we try to get the cooling sorted.

My dad has today installed a brand new fan, but as yet it is still not turning on.

I'm pretty sure we've already replaced the relay and expansion tank cap, checked all the wiring, and a whole host of other things, but nothing seems to fix the problem.
Am I looking at a new ECU or is there something that I've overlooked?

cheers all.

Oh, by-the-way, the car is a 98 Cooper MPI.

Does this problem exist with the SPI ???

I am not sure if mine comes on or not.

You can test the auxiliary cooling fan on an SPi Mini and Cooper by removing the 2 spade terminals from the lower front of the radiator, connecting them together with a paper clip and then turning on the ignition.

The auxiliary cooling fan should then spin.

If it doesn't then check the in-line fuses on the bulkhead behind the air filter box: -


In-Line Fuses situated behind air-filter on the bulkhead: -


15amp - Purple/Orange Wire
Hazard Warning & Interior Lamps


15amp - Brown/Orange Wire
Dim-Dip Lighting


10amp - Blue/Orange Wire
Rear Fog Guard Lamps


15amp - Blue/Red Wire
Auxiliary Cooling Fan (where fitted)
