When I turn my car off the fan continues to run?
It’s normal for some vehicles to have a fan run for a few minutes after the car is shut off, generally to keep the engine cool. It’s possible you may have a module or relay failing in your car. Have a mechanic inspect the electrical portion of your cooling system to be sure it’s running correctly.
What does the fan on the engine do?
The engine fan is located behind the radiator and designed to draw air through it. This helps to keep the engine at the correct temperature. It is controlled by the temperature of the coolant. When this reaches a certain point, sensors inform the car’s computer (ECU) which tells the fan to switch itself on.
Why is my engine fan always on?
It is possible that this problem of your car’s fans constantly running is some sort of mechanical or electrical error from a poor sensor or other component. There are temperature sensors and some cars have separate sensors for the gauge itself. The fan can be shut off when the engine temperature warrants.
Do both engine fans run all the time?
Even with the cooling fans running all of the time, the engine thermostat should force the engine to warm up at a normal speed. The thermostat will regulate the coolant to the radiator/fans if it is working properly. It can be normal for the cooling fans to run constantly under certain conditions.
Can a car fan still run after the engine is turned off?
Then you notice the engine cooling fan is still running even though the car is turned off. It is ok for the engine cooling fan to keep running for a few minutes after turning off the car.

What happens if your car cooling fan is too low?
If the motor that drives the fan is faulty, then a new motor will have to be fitted. Check the engine coolant level. If your engine coolant’s too low, it means that the cooling fan will have to work harder to keep the engine at a normal temperature.
Why does my TDI cooling fan run after shutting the engine off?
Since the vehicle does not know you are only going on a short trip, it may start this process just before you arrive at your destination and now that engine is switched off and the vehicle is stationary the system will self-activate the cooling fans at high speed in an attempt to bring down those high temperatures now trapped below the hood.
