The cooling liquid passes through a thermostatic valve opening at 82°C.
So,in normal conditions (speed>50kmph, outside air temperature less than 25°C),the cooling liquid should be at 82°C or a little more,not more than 90°C.
During traffic troubles (speed<50kmph),and/or hot season,the liquid temperature may be more,but never above 100°C.
The fans are regulated by the only water temperature sensor: at about 90°C,first speed (low);at about 95°C,second speed (high), both fans run simultaneously.
Even during very hard conditions (track day,hot climate),the water temperature might not be more than 90°C.
