Two summers ago I tracked my coolant temperature for a few days at random. Outside temp was 20-25C. Temp seemed to wander around a lot and not follow specific activities. As I recall the range was 90-106 with it trying to control to 100. Only once or twice have I been aware that my radiator cooling fan had operated.
