Abstract: 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.

Abstract: When a temperature of cooling water detected by a water temperature sensor is, for instance, higher than, or equal to degrees, and is smaller than degrees, an abnormal state judging unit judges that an engine is under semiwarming-up condition, and then forcibly drives an electric motor fan so as to forcibly cool cooling water contained in a radiator. After the abnormal state judging unit has forcibly driven the electric motor fan, this abnormal state judging unit calculates a difference between the cooling water temperature detected by the water temperature sensor and a predicted cooling water temperature. When the calculated temperature difference is smaller than a predetermined abnormal state judging value, the abnormal state judging unit judges that a thermostat provided in a cooling water circulating path is brought into an abnormal valve opening state.

In another example, it is determined whether the engine had reached the desired warm condition according to whether a vehicle-related process is activated.
