The system is characterized by comprising an electromagnetic clutch water pump, an electronic thermostat, a driving grille, an electric control fan and a controller, wherein the electromagnetic clutch water pump is arranged on a converging pipeline of the small circulation pipeline and the large circulation pipeline; the electronic thermostat is arranged on the large circulation pipeline; the driving grille is arranged on one side, facing the vehicle advancing direction, of the engine; the electric control fan is arranged between the driving grille and the engine; and the controller is electrically connected with the electromagnetic clutch water pump, the electronic thermostat, the driving grille and the electric control fan. The system can respectively control the running speed of the electromagnetic clutch water pump, the working state of the electronic thermostat, the opening degree of the driving grille and the rotating speed of the electric control fan according to the current engine water temperature, the current engine rotating speed and the current engine air inlet temperature. The oil consumption of a vehicle is reduced while the water temperature of the engine and the air inlet temperature of the engine are kept in the optimal temperature interval.
