。In a cooling system for an internal combustion engine, in which a water pump leads a coolant from a water jacket of a cylinder block to a water jacket of a cylinder head, the temperature of the coolant is controlled according to the engine load. a coolant branch passage that allows communication between the discharge side of the pump and the over-jacket of the cylinder head; and a coolant branch passageway that allows the coolant discharged from the water pump to flow only when the engine is under load such that the liquid temperature is low. A cooling device for an internal combustion engine, comprising a switching valve that is controlled to conduct a portion of the cooling fluid to the water jacket of the cylinder head via the branch passage.
