Mini Cooper -- temp gauge to red zone, fan comes on

For the past year, my 2005 mini cooper with 41000 miles on it has done the same thing. I have replaced the temp sensor and the thermostat as well as the radiator cap -- had system flushed repeatedly. Wiring to sensor replaced -- STILL DOES THE SAME THING. Experimenting to see if it's a grounding problem but still can't figure it out. Has been to three different mechanics. Nobody has a clue.

    I am not sure when the fan comes on; it's just on when I stop the car. I can't hear it while I'm driving.

    I don't think the radiator has debris in front of it -- but I will check.

    how do you tell if a cooling system requires "bleeding out air"? it seems as if when i open the radiator and allow it to "air out" that the problem stops ... but my mechanic INSISTS there's no possible way the radiator has air pockets in it. Maybe he's an idiot?

    Yes, it is the original water pump.

Mini Cooper temperature gauge goes to red zone when idle

check coolant level could be too low allowing air in the cooling system causing air pocket in engine around the engine coolant sensor.coolant sensor needs to be in hot coolant so it will cause the cooling fan to come on at a set temperature.make sure coolant correct level and the coolant level in the cooling overflow jug should be at full cold mark.the cooling overflow jug should never be empty,if you see empty cooling overflow jug air got in the cooling system so make sure when engine cold every time raise hood make sure cooling overflow jug coolant level at full cold mark.if jug stay empty you have cooling replace radiator cap,if coolant level all good,i would replace the engine coolant temperature and thermostat.when your car come to a long stop or driving along long line of slow moving traffic the engine coolant blower motor should running if not have vechicle code scan for faulty coolant fan motor control module.or ecm problems.

My 2005 mini cooper battery light came on today. first it was flashing while i was driving and now i have a steady battery light on. i just had the battery replaced early this year. and altenator replaced...

have battery and alternator tested for free at parts store its one of them check make sure you have the correct amount of cooling fluid in radiator fans will come on on some cars after you turn them off to coll them down to proper temps ive had hondas thats done the same thing thats normal as long as your antifreeze isnt low

2004 mini cooper fan starts running while idle. temp red lines when idle?

You either have a leaky hose or need a thermostat the fan is designed to come on to cool the radiator down when the engine heats up. have flushed your system lately it you may need to do this as well.

the fan is running because the sensor is picking up a hot spot(top of the engine(head)when you switch on again the computer is verifying the engine temp)to see if it needs choke)then shutting down the fan.....this is why one needs a computer to find out whats what with modern cars......

Temperature gauge back and forth between normal

the fan comes on and off based on the "temperature sending unit" thats a thermal switch mounted on the radiator .. it is normal for the temperature to fluxuate as the fan turns on and off .. if it is allowed to get too hot before turning on then the temperature sending unit should be replaced ...while the car is moving the fan may never come on and isnt needed as long as air is flowing through the radiator .. as long as you are not loosing coolant then the temperatures are probably within proper range ... a sticking thermostat can also cause increased temperature range fluxuations .. that will show up as large swings of temp while driving .....

2006 mini w/ 30k miles. when stopped, temp gauge shoots up to the red zone. when i start driving again, it drops back down. also, unsure if related, but heat will not blow hot. what could it be?

most likely is going to be a bad thermostat. when you are moving cold air comes through the grill cooling engine but when you stop you don't have that air and thermostat is not allowing flow causing overheating.

Mini Cooper temperature gauge goes to red zone, fan comes on

If you have a new thermostat, then your temp sensor is faulty. If sensor is new, then it is the wiring to sensor or problem with the ECM

Mini Cooper convertible is overheating, fan contiues after stop

I had this exact same problem -- for about a year and a half! Replaced thermostat, replaced sensor twice, replaced overflow tank, replaced radiator cap, placed a grounding kit on the car in case the problem was electrical ... and was ABOUT to replace thermostat again and then the water pump when a new mechanic suggested we bleed air out of the cooling system. The heater core was PACKED with air, as was the upper hose valve area. Previous mechanic had been using a pressurized fill device to bleed the system and this had just been backing air into the heater core. There are two valves under the hood for bleeding air -- one on the heater core and one on the upper hose. It only takes a few minutes to fix this!
