I agree it takes a lot for my temps to go past 200... like a big hill pulling 14,000 lbs and even then it barley hits it.
I've found it's easy for me to make the temperature rise unloaded.
The center mark on the gauge is about 196°F. I've seen as high as 198°F on a long pull up a decent grade during hot weather (but running empty).
I've always assumed that if I were pulling 7 tons or so I'd easily see 210°F in the same conditions. But maybe I'm wrong.
