It is normal for the cooling fan to run for a few minutes after the engine is turned off. This is to help dissipate any remaining heat from the engine and prevent it from overheating. If your cooling fan is running excessively, you may need to have your radiator, thermostat, or water pump checked.
In some cases, the cooling fan may run longer than usual after the engine is turned off. This is common if the engine was running under heavy load or in high ambient temperatures. The fan will continue to run until the coolant temperature drops to a safe level. If you notice that the cooling fan is running excessively, it is important to have your vehicle checked by a qualified mechanic.
