To provide a radiator cooling system that can reduce a power consumption of an electric pump that generates a driving force for moving cooling water and a driving force for rotating a fan that cools a radiator.SOLUTION: A radiator cooling system includes: a fan located behind a radiator and rotating around a rotary axis to generate negative pressure; a cooling water channel connected to the radiator; an electric pump that moves the cooling water along the channel; a water wheel that is rotated around its axis by the cooling water flowing through the channel; a water temperature sensor that detects an inlet water temperature of an inverter that is cooled by the cooling water; and a control part that performs PWM control of the electric pump based on a map 40 that defines a relationship between the inlet water temperature, a vehicle speed value that indicates a vehicle speed, and a duty ratio of an electric power supplied to the electric pump. The map specifies that when the vehicle speed value is equal to or greater than a first predetermined value and equal to or less than a second predetermined value and the inlet water temperature is equal to or greater than a third predetermined value, the duty ratio is decreased as the vehicle speed value increases.SELECTED DRAWING: Figure 5
