Abstract: A cooling control system for an internal combustion engine, which is capable of circulating engine coolant while suppressing power consumption by an engine coolant pump as much as possible. The cooling control system is provided for cooling intake gases increased in temperature by being pressurized by a supercharger. The engine coolant pump of the electrically-driven type delivers engine coolant to thereby cause the same to circulate. An ECU controls, when a difference between the temperature of the engine coolant and a first target temperature is not larger than a first predetermined value, the amount of the engine coolant to be delivered to a predetermined minimum flow rate, and controls, when the difference is larger than the first predetermined value, the amount of the engine coolant to be delivered such that it becomes larger as the difference is larger.

Abstract: A cooling control apparatus for an internal combustion engine with a supercharger includes an internal combustion engine cooling circuit, an inhaled gas cooling circuit, a cooling water introducing passage, an overcooling determination device, and a temperature-decrease controller.
