United-Kingdom '02 Mini Cooper 1st stage fan not working

Hi, I have a 02 Mini Cooper recently purchased from a private seller but i have started noticing slight problems with the fan and coolant levels.

It started off with the car blowing cold air in the interior and the coolant levels dropping and the 2nd stage fan staying on for about 10 mins after the car was turned off. My first trip to the mechanic concluded that it was the radiator cap that was not holding the pressure and leaking out of the cap, so got that replaced for around 10. After that the car was running fine for a couple of weeks.

Now the problem has extended to the radiator fans not coming on at all, causing the car to overheat when stationary

Went back to the mechanic and he goes that it may be an electrical fault as the stage 1 fan is not kicking in, however the 2nd stage works. Suggested that I replace the whole fan unit or wait 2 weeks for the electrician to come in (not a possibility, cant be off-road for 2 weeks!)

So i made a trip to a local breaker who had the correct part available for 20, however before I bought the part I plugged the fan in to see if it would work(externally) but no joy, fans didn't turn and the engine was running hot. The breakers told me that it may well be the fan switch which is mounted to the head, however that would cost a bomb of labor to replace.

Now I'm not sure what to do, I don't want to waste money on repairs that are not necessary, so any advice on this would be greatly appreciated

I would also like to add that the temperature readings on my tachometer are fluctuating between -50 and 50 which kind of backs up that it may be one of the sensors that are gone?

Hi ya

I take it that you have checked the first stage fan relay and fuse there in the engine bay.

There us a good chance the fan resistor has gone, if you do a search for first stage fan resistor you will find loads of ways to rework the system.

I personally bought a 60 ohm resistor and spliced it in :-) from bmw p/no 51337071670

Have a read though this link it's a long one but good info it may help

http://www.northamericanmotoring.com...-solution.html

As for you temp gauge it sounds like you have a problem with your OAT probe you may have a bad connection of some damaged wires, it's behind the front bumper right hand side as you look at the front of the car. You will need to pull the bumper off.


Hope this helps

Yeah thats the other thing that crossed my mind, but isnt the resistor mounted on the fan assembly? because I have already tested another fan unit.

Thanks for your reply!

Hi ya

Sorry must have been adding it as you was replying.
On my MCS I mounted my resistor on the aluminium cross beam.

UPDATE: I have taken the car to the mechanic who has concluded that it was the fan switch that was faulty. The car now doesn't overheat anymore however the 1st stage fan still doesnt seem to come on!

The mechanic said it needs a whole fan replacement to get 1st stage working again but its fine to drive without it working? Is that true? Opinions please

Hi ya

I take it your mechanic has tested the low speed fan wiring fuses and relay.
Simple and quick to do. Disconcert the black plug for the fan ( left hand chassis leg near bonnet release) there a three wires in the plug one is earth (brown) and the other two are power to the fan one is high speed red/blue 4mm cable) and one is low speed (red/blue 2.5mm cable). Run the car till the first stage is meant to cut in, if you have voltage between earth and low speed fan power your good

If the above is ok and the second stage fan work it's only the resistor

Just replace the resistor it's a very simple job it will take about 1 to 2 hours

You have a few choices as I said above or you can buy these

Splices
10 x Butt Splice blue with heat-shrinkable tubing... 10 x Butt Splice blue with heat-shrinkable tubing...
Resistor
BMW MINI ONE COOPER S 1.6 R50 R53 RADIATOR COOLIN FAN RESISTOR SWITCH REPAIR KIT | eBay

Or

Search SiteSearch 17117541092 - 17117541092R - Cooling Fan Resistor Repair Upgrade Kit - ES#2709851

And stay standard ish simple fix :-)

Hope this helps
