I have 2003 Gen 3.
While pulling 6000 lb trailer to my hunting area temperatures ran 212 to 223 in stock.
Exhaust manifold 1250f and no power, but fuel dumps at that temperature.
I had to go at 30 mph up hills.
I have an Edge tuner.
I’m thinking I need a complete engine flush and new thermostat.
Never been done.
No smoke.
Any other ideas?
