The embodiment of the invention discloses a cooling system fault judgment method and device, electronic equipment and a storage medium. The method comprises the steps that the detection temperature of a cooling system, the actual rotating speed of an electronic water pump and the actual rotating angle of a temperature control module are obtained; determining theoretical inlet branch flow and theoretical outlet branch flow of the electronic water pump according to the actual rotating speed of the electronic water pump and the actual rotating angle of the temperature control module; the theoretical inlet branch flow and the theoretical outlet branch flow are corrected according to the detection temperature, and the actual inlet branch flow and the actual outlet branch flow are obtained; the outlet temperature of the expansion water tank is determined according to the actual inlet branch flow and the actual outlet branch flow; and performing fault judgment on the cooling system according to the outlet temperatur
