装置。[Scope of Claim for Utility Model Registration] A cooling control device for an internal combustion engine in which air is blown to a radiator by a cooling fan, comprising a water temperature detection means for detecting the temperature of cooling water of the internal combustion engine, and a water temperature detected by the water temperature detection means. control means for increasing the rotational speed of the cooling fan when the cooling water temperature is equal to or higher than a first threshold; and for decreasing the rotational speed of the cooling fan when the cooling water temperature is lower than a second threshold that is lower than the first threshold; and a speed detection means for detecting the traveling speed of the vehicle, and based on the detection result of the speed detection means, the first
and/or threshold value correction means for correcting the second threshold value.
