In the Fukuda era, the engine turned off and the iron rang.

The reasons are as follows: 1. The engine's cooling fan will automatically cool down. When the engine temperature is too high, even if the car is turned off and the car key is removed from the car, its cooling system will automatically start to cool the engine system. The reason why it makes a whirring sound is because the electric fan is running at high speed. Car owners don't have to worry about this situation, because the cooling system will automatically stop working after the temperature of the engine system drops, which usually takes 3 to 5 minutes. 2. The engine really can't put out the fire, and the piston and crankshaft are still turning. Try to restart the car. If it can be restarted, there is no problem with the engine; If the restart causes the engine to make abnormal noise, you can hear obvious noise and need to check the car carefully.
