ン冷却用電動フアンの制御装置。 An intake air amount correction means that increases the amount of intake air when a load is applied in a low load range including an idling operating state, and an engine cooling system that is activated when the engine cooling water temperature exceeds a predetermined set temperature. The engine includes an electric fan and the intake air amount correcting means is activated at least when the electric fan is driven. When a certain thing is detected, the electric fan is driven when the engine cooling water temperature becomes equal to or higher than the first set temperature, while when it is detected that the engine is in a high load region, the engine cooling water temperature is changed to the first set temperature. 1. A control device for an electric fan for cooling an engine, comprising an electric fan drive control means for driving the electric fan when the temperature reaches a second set temperature lower than the first set temperature.
