Why does the fan keep running after the car is turned off?

Vehicle fan keeps running after the engine is turned off because the engine temperature remains too high after parking. The onboard computer automatically calculates the fan speed and duration - the higher the engine temperature, the longer the fan will run to protect the engine. If the fan continues running after the engine temperature has dropped, it might be caused by a poor electrical connection. You can try unplugging the fan wiring harness to cut power separately. The function of the car fan is to increase air flow through the radiator core, enhance cooling efficiency, and accelerate water cooling. Automotive engine fans are classified into axial-flow fans and centrifugal fans by structure principle, and divided into mechanically driven and electrically driven types by driving method.
