Abstract
An engine cooling system includes a coolant circulation path, which circulates coolant between the water jacket and the radiator of an internal combustion engine, a pump, a control valve, which is provided in the coolant circulation path, and a controller. The controller executes a warming-up promotion control and a pressure relaxation control. In the pressure relaxation control, the controller controls the aperture ratio of the radiator port such that the lower the temperature of the radiator, the lower becomes the engine rotational speed at which the aperture ratio of the radiator port is increased.
