A control device of a vehicle radiator system mainly has a temperature comparator, a temperature sensor, a keyboard and a display. The temperature sensor is positioned near an engine of the vehicle and outputs a detecting signal to the temperature comparator. Since the temperature comparator has a preset temperature value, the temperature comparator compares the preset temperature value with a current temperature value in the detecting signal to determine whether a start signal is output to a water gate driver device and a fan driver to open the water gate and start the fan drive. Since the vehicle driver sets the current temperature value through the keyboard and the preset temperature value is lower than an original fixed over-heat temperature value in the radiator system, the radiator system can be started appropriately to ensure the engine works at a safe temperature condition to prevent damage to its components.
