PURPOSE:To facilitate the exhaustion of the air in a suction air cooler by a structure wherein the upper tank of an engine radiator is connected through a valve, which is open when applied by the pressure exceeding a predetermined pressure, to a radiator to cool the cooling water of the suction air cooler and a reservoir tank is connected to the radiator. CONSTITUTION:High temperature cooling water leaving an internal-combustion engine 1 is introduced in the upper tank 9 of an engine radiator 7, heat-exchanged with air at a core section 10 and cooled, and, after that, returned through the lower tank 11 to the internal combustion engine 1 in the cooling apparatus of the internal combustion engine 1. On the other hand, cooling water leaving a suction air cooler 15, which is arranged in the midway of a suction air passage 2, is introduced in the lower tank 22 of a radiator 16, heat-exchanged with air and cooled, and, after that, returned through the upper tank 19 to the suction air cooler 15. In this case, a cap 24, which is open when the pressure in said tank 9 exceeds a predetermined value and the outlet pipe 31 of which is connected through a water circulating pipe 32 to the upper tank 18 of the suction air cooler 15, is fitted to the tank 9. In addition, the upper tank 18 is connected to a reservoir tank 40. |
