Overheating
I am having a problem with the clutch fan not coming on at high temps pulling a grade or flat. Replaced the clutch had the front of the radiator removed and all the debris blown out and replaced the thermostat. Still over heating and the fan comes on real late.

Have you considered the radiator could be partially plugged in it's lower section reducing it cooling capacity.
It may cool under light load but overheat under heavier loads.
It may be the cap has failed, as well.
Good luck.
