Why does my radiator fan stay on when my car is off?
When the engine is running, the coolant circulates and flows to the radiator, where heat is dissipated. When the engine is turned off, the coolant doesn't circulate, and the heat stays trapped, therefore prolonging the engine from cooling. Running cooling fans help cool down the engine even after you turn off the car.
Why does my car cooling fan keep running?
3. Cooling fans stay on at all times. If the cooling fans are staying on at all times, this is another (less common) symptom of a possible problem with the cooling fan relay. If the relay shorts internally, it may cause power to be permanently switched on, which will cause the fans to run at all times.
Why won't my cooling fan shut off?

Why does my radiator fan keep turning on and off?
vehicles with electronic cooling fans turn on and off to help regulate the engine temperature. if the regulator senses that is getting too hot it kicks the fan on to cool the radiator down. when it is cooled down enough it kicks off and allows the engine to heat back up.
How do I know if my radiator fan motor is bad?
The most common symptom that the radiator fan has gone bad is that it will stop working. Sometimes the motor burns up or fails. Other times, the relay stops working. Either way, you know there is an issue with the fan system if it is unable to run.
