Abstract
A cooling system includes: a shutter grille provided to an air guide port configured to guide air to a power compartment in which a power source of a vehicle is installed; a radiator configured to radiate heat from coolant for cooling the power source; a radiator fan configured to send the air to the radiator and the power source; a shutter grille controller configured to control opening and closing of the shutter grille; and a radiator fan controller configured to control the radiator fan. If a power source load on the power source is less than predetermined power source load, and if an air conditioning load on an air conditioner is equal to or greater than predetermined air conditioning load, the shutter grille controller and the radiator fan controller operate the radiator fan with the shutter grille closed.
