Fan Keeps going.

My 1.8T ZT+ electric fan keeps going nearly all the time . When you turn the car off it still goes for 2 mins even though its its freezing outside and I have done 3 miles.
Any Ideas Please.

Is the fan controlled by an otter switch, or is it done electronically?

[mightydquinn]

its however the car is from new.

[GreenV8S]

Pardon?

[mightydquinn]

I mean
I dont know but it is however MG built it in the 1st place.
Is that a bit clearer.

I don't know how the fan is controlled on that car, but from what you've said my guess is that it is controlled by the ECU. It would make sense for the ECU to run the fan when it see an excessive coolant temperature, so one possible explanation is that the coolant temp sender has failed or there is a wiring fault. Most coolant temp senders are a simple thermister with a resistance that goes down as the temperature goes up. It could be that the thermister has failed, or there is a short in the wiring to it. If that was the case you might also find that the engine runs very rich and gives very poor economy. Ring any bells?

you sure its not just circulating coolant / etc to cool the turbo after switch off?
Check the manual for details..

Most modern cars do this, any Alfa Romeo or Peugeot owners will testify to this, Don't worry, I would think its probably normal, quite often its due to the temp sender being in the top of the head and the hot water rising when the engines switched off, other times its a built in program to the ecu to run the fan for about 2-3 mins after every switch off.

Not a problem. Oft discussed on the MG forums. Mine does exactly the same. It is a bit irritating to be honest but only occurs with the air con on auto. Set it to econ and it should stop unless it gets too warm
