The present invention provides a cooling controller featuring fail-safe capability that keeps the internal combustion engine from overheating, having a butterfly valve 34b for adjustment of cooling fluid flow that is driven by the motor 31, the clutch 32 and the reducer 33, thus cooling the engine to a proper temperature during operation. Said butterfly valve 34b is pushed by the return spring 34e toward the open-valve direction and having the rotation angle for testing the butterfly valve 34b, such as the angle sensor 34g. In the calculation means, an abnormal state determined on the data of the coder 34g and the cooling water temperature, the clutch 32 would be released and the butterfly valve 34b would set open automatically. Consequently, overheating in the engine would be prevented.
