PURPOSE: A suction air control device of a radiator for a vehicle is provided to maximize efficiency of the radiator by controlling the amount of air coming into the radiator according to the traveling speed when the temperature is low. CONSTITUTION: In a radiator grill(10) mounted in front of a radiator, with multi-stage partitions(11) continuously formed, a control valve(20) for suction air control with the opening and shutting angle changed according to the traveling speed is removably mounted between the partitions of the radiator grill. The control valve is installed between the partitions oppositely and is opened and shut while vertically moved according to the strength of the wind during traveling. Thus, the amount of air coming into the radiator is effectively controlled.
