The cooling fan temp sensor detects the coolant is hot and it will remain on until the coolant cools down, usually in a few minutes. Check the coolant reservoir to be sure the coolant is at the proper level.

fan stays on when car turn of
The cooling fan is electric and the sensor reads that your car is hot. It stays on, even when the car is off so that it can cool your engine to acceptable temperatures. If it didn't, and the car remains too hot, it can warp parts and destroy your engine. If the fan runs for an exceptionally long time, and drains your battery giving you a no start or weak battery slow start condition, you may have a bad cooling fan relay.
get in the car when it is cold, turn on the ac, then check under the hood. the fan that is not spinning when the car is cold is the cooling fan
your cooling fan(s) is/are not working your cooling fan(s) is/are not working
when the car starts to over heat
You have to be more specific. Which fan? Blower motor for the heat/ac.......clutch fan for cooling.......electric fan for cooling.....? Wish I could help, if you can add more info, just send it to me on my board.
If your computer is shutting down, or of the fan is always running on high.
The electric cooling fan or cooling fan temp sensor may be faulty.
When operating properly, the cooling fan stays on until the temperature drops to normal.
unless there is something wrong with your car, the cooling fans are activated when a sensor in the cooling system detects that the coolant is too hot and that is when the fans turn on to help bring airflow to the radiator or just to circulate hot air away from the engine. if the coolant is still hot when your car turns on, then the fan will stay on as well. Also, if the AC is in the on position both the fans will run.
If the temperature of your car engine is still very high after stopping, the car cooling fan will continue to run, and the cooling fan will not work until the temperature drops.The above answer comes from Suzhou Santian Precision Mould Manufacturing Co., Ltd.
A working cooling fan is important in keeping the engine of a car running well. A diagram for a cooling fan in a Honda Accord can be found in its maintenance manual.
