Hi there. It is common for the raditator fan to keep running for about a minute or less after the engine is shut off; especially if the engine temperature is extremely hight. Typically when the fan keeps running after the vehicle is turned off, it’s caused by a relay that is bypassing the ignition relay input. It might be best for you to have a professional mobile mechanic complete an electrical problems inspection to help you pinpoint the source of this problem
