Cooper s boils up

Hi, im new to this forum. I have a 53 plate cooper s and it runs and drives lovely. How ever when im stuck in traffic it starts to boil up befor the fan kicks in. When the fans running it continues to boil and spits all the water out the expansion bottle. Anyone have any ideas? Does the fan have two stages as when it comes on its going that fast the hole car shakes and it sounds like an aeroplane its that fast.
Thanks in advance

This is a common problem and there are many threads on this if you search on Mini2. The fan has two speeds and it sounds like your first stage fan has failed. Usual cause is a resistor.

Hi ya

Pretty much as mab says
but I would also say your thermostat could be playing up.
But please remember these minis do run hot first stage cuts in at 105 and second at 112 deg c so using the correct antifreeze/coolant is very very important as it needs a higher boiling point.
Halfords sell it this is what I always use just and it's approved for the mini mix 50/50 and bleed the system properly

Halfords | Comma G48 Antifreeze and Coolant Conc 2L

I would also say if you do not have one all ready but a diagnostic tool or scan gauge so you can check the water temps remember the gauge on the speedo is just a trinket it's only for show

Hope you get it sorted just take your time bleeding it

Just had it plugged in, i have 2 fans one on the car, and a spare. I had the computer test stage one of the fan and on both fans only the power steering pump comes on. Is this normal, or should the rad fan come on to at a low speed? Thanks

Hi ya

Don't mess with the computer for now.
disconnect the plug on the chassis leg for the fan and do a resistance/continuity check.
You have 3 wires one brown and the other are blue with a red tracer. You will see one or the blue/red wire is thinner than the other that one is your first stage fan resistor, go between the brown and the blue/red wire check for continuity. If you have none the resister is shot common fault easy to fix.
If you stay on the brown wire and go on to the others blue/red you will have continuity. That's the second stage fan.

If the resistor is bad you will need one of these

Hope this helps

Ps I take it you have checked all the fuses and relays but doing this continuity check will tell what direction to go in

All sorted now. Put a new fan in it. First stage comes on at 105 and never got hot enough for second stage to kick in and was left running 30-45 mins
