Fan Running / car off

[timsdrums]

I am a new Z4 owner, finally traded up from the Z3... day 3.... when you turn off the car the fan in the engine compartment runs for a bit.... even after short jaunts.... is this a problem? it is raining and about 55 degrees out so not hot...

cheers... pics soon

i believe this is normal i used to have this happen on a short 4 mile journey i took back and forth everyday - once the car got up to temp and you gave it some then stopped shortly after turned ignition off the fan would run fast for about a minute. It has something to do with short journey combined with putting your foot down! Thinking about it I don't make many short journeys where you can get speed up and have not heard the fan for a while at least a good couple of years! it had nothing to do with the weather or how hot it was.

hope this helps

The coolant temperature of a warmed engine will actually rise for a while after shutting the engine off. This fan is responding to the coolant temperature sensor output and helps to reduce the temperature increase.
