coolant temperature changed
I have had this coach for about 3 years. The engine temp has always ran about 195 to 199 degrees unless it was very hot outside(90 to 100 degrees). On those very hot days it would go up to about 205 d...

Thank-you for all the suggestions. To my knowledge(I don't have any receipts showing a coolant change)so I'm guessing that the coolant and thermostat have never been changed.
I was wondering if the coolant was aged out and could cause the engine to run hotter than what it used to be. A coolant and thermostat change will probably be the first thing I do to see if it starts running at 195 degrees again.
It has a rear side mounted radiator with a hydraulic fan so the suggestions of bugs, grill guards, and fan clutch don't really apply in this set-up. I do check those things on my other vehicles though.
Thanks to the poster about checking for a weak or partially collapsed hose. I hadn't thought of that and will do that next time I have it at operating temperature.
On edit...I have heard that "water wetter" is a good product, but I don't add anything to the coolant except what Cummins recommends.
