Coolant Temp Indication Problem?
On the road, my temp indicator on a 95 PS moves up and down from the "R" to the "M" in the "NORMAL" range, sometimes higher, and back, based on speed and hills. Is this normal or an indication of a thermostat going bad because it is not maintaining a constant temp?

Coolant Temp Indication Problem?
The cooling system on these trucks, when operating properly, is very efficient, and my needle doesn't move once warmed up. I'd suspect your thermostat isn't opening properly.
