A water spraying device for a radiator includes a radiator(1), a tank(2), a water spray pipe(3), a radiator supporting member, a plurality of nozzles, a pump(6), a water supply pipe(7), an ECU(Engine Control Unit), and a temperature sensor(8). The tank is installed on a lower part of the radiator. The water spray pipe is formed on a front part of the tank and is elongated lengthwise of the tank. The water spray pipe is fixed and mounted on the radiator supporting member. The plurality of nozzles are formed lengthwise of the water spray pipe. The pump supplies the water spray pipe with high pressured water. An outlet of the pump is connected to the water spray pipe by a medium of the water supply pipe. The ECU controls driving of the pump. The pump is connected to an output stage of the ECU. The temperature sensor is connected to an input stage of the ECU for sensing an external temperature.
