<p>The IC engine vis equipped with a supercharger which makes it necessary to water-cool the supercharger and at the same time, to remove air mixing into a cooling water circulation path to attain high cooling efficiency. This invention forms communication paths (20,22) for communicating the upper end portion (18) of a cooling water path (7) circulating inside an internal combustion engine (1), a cooling water path circulating inside a supercharger (17) and an upper tank (15) of a radiator (2), and effects simultaneously water cooling and air separation of the supercharger by use of these communication paths (20, 22). To be more specific, cooling water that cools the internal combustion engine (1) is led from the upper end portion (18) of the cooling water path to the cooling water path inside the supercharger and cools the supercharger and at the same time, the mixed air that stays at the upper end portion of the cooling water path is led into the upper tank through the cooling water path inside the supercharger. Air separation from cooling water is made in the upper tank and cooling water not containing the air returns again to the cooling water path.
