。[Scope of Claim for Utility Model Registration] A cooling fan driven by an electric fan motor and a water temperature switch that controls the operation of the fan motor according to the engine cooling water temperature. The electric type engine is such that the fan motor is deactivated when the engine cooling water temperature is below a predetermined value, and the fan motor is activated when the engine cooling water temperature becomes higher than the predetermined value. The cooling fan control device includes a gear position detection sensor that detects the position of the drive gear of the vehicle, a fan motor operating state detection sensor that detects the operating/non-operating state of the fan motor, and an output signal of the gear position detection sensor. When the drive gear changes from the neutral position to the drive position, the fan motor control function of the water temperature switch is activated for a predetermined period of time based on the output signal of the fan motor operating state detection sensor. An electric cooling fan control device for an engine, comprising: a control device for disabling the fan motor control function of the water temperature switch after a predetermined period of time.
