<p>PROBLEM TO BE SOLVED: To provide a cooling device for an internal combustion engine, capable of suppressing the occurrence of noises due to bubbles when cooling water flows in heat exchangers.SOLUTION: A cooling device for an internal combustion engine for circulating cooling water in heat exchangers such as a radiator 7, a heater core 11, and an oil warmer 12, and an internal combustion engine 2, includes a first control valve 14 for restricting the outflow of the cooling water from the heater core 11 and the inflow of the cooling water into the heater core 11, when closed. The cooling device for the internal combustion engine further includes a second control valve 15 for restricting the outflow of the cooling water from the oil warmer 12 and the inflow of the cooling water into the oil warmer 12, when closed. The cooling device for the internal combustion engine holds the first control valve 14 and the second control valve 15 in closed states during a time from starting the discharge of the cooling water from the cooling device to finishing the filling of the cooling water into the cooling device.</p> |
