Then figure out why it did and repair the problem. Faulty water pump, burnt out coolant, faulty thermostat, blockage in the cooling system, damaged radiator fins... those are the culprits I'd look at. Blown head gaskets are a common consequence of an overheating vehicle.
has the car been overheated?
The thermocouple which measured the car's coolant temperature failed and so the car overheated.
it means that the car wasnt overheated enough to gt to that point
we have to put the gear to neutral and apply brakes, and start the car.
hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha
So, ... what is your question?
blown head gasket
The fan itself, its fuse or thermostat.
It says that, because your engine overheated.
If the car overheated, you may have warped the aluminum head. You may have to have the head shaved and a new head gasket put in.
Check wikipedia on this sounds like a problem these cars have, that I read about on there.
Have you checked your thermostat?
