How Long Should Engine Fan Spin After?

You may rest certain that everything is running as it should. Leaving the cooling fans running is intentional, and it can occasionally persist up to 16 minutes after the engine has been turned off. The after-running procedure avoids excessive engine compartment temperatures induced by the diesel particulate filter regeneration cycle from occurring in the engine compartment.

How long should a cooling fan run after turning off the engine?

Even after you turn off the automobile, the cooling fans continue to work to cool down the engine. If your cooling fan continues to run after you have turned off the engine for more than 10 minutes, you may have an issue that has to be addressed.

When you stop driving, the fan kicks on to ensure that no more cooling air is drawn into the engine compartment by the radiator. Because of this, the temperature rises and the fan begins to operate automatically. It is expected that the fan will turn off after the temperature has reduced once more (which will occur because the engine has been turned off).

What causes an engine to keep running after turned off?

While driving, the engine may continue to turn after you have turned off the ignition because the fuel/air combination is being ignited by a hot-spot in the combustion chamber, which is known as running-on.

Do radiator fans always spin?

The temperature will frequently decide when a radiator fan will begin to operate. The fan is controlled by a temperature-sensitive switch that turns it on and off at regular intervals. Coolant radiator fans are programmed to activate when the temperature of the engine coolant rises to around 200 degrees Fahrenheit.

How do I know if my radiator fan is working?

Simply starting your vehicle and turning on the air conditioning system (A/C) to its highest setting can reveal whether or not your vehicle’s radiator fan is functioning properly.

Why is my engine fan always on?

When the automobile radiator cooling fan continues to run continuously, the most common causes are a malfunctioning coolant temperature sensor or its wiring, a broken fan start relay, damage to the electrical connections, and difficulties with the electronic engine control unit (ECU).
