To provide a cooling system for an internal combustion engine capable of efficiently cooling the internal combustion engine.SOLUTION: A cooling system for an internal combustion engine includes: a cooling circuit in which cooling water for cooling the internal combustion engine circulates; an electric pump for circulating the cooling water in the cooling circuit; a plurality of components provided in the cooling circuit; a plurality of bypass circuits each provided corresponding to each of the components so that the cooling water bypasses the component; a control valve that switches flowing of the cooling water to either one of the component or the bypass circuit; and a control device that controls opening/closing of the control valve and controls the output of the electric pump. When the cooling water is caused to flow in the component, the control device controls the output of the electric pump on the basis of the type of the component in which the cooling water is caused to flow.SELECTED DRAWING: Figure 2
