Over heating???

My 05 gets hot when I'm pulling 5k or more mostly up hill. Then if I get off pedal it will cool off quickly then I cruise with no problem. Only if I leave degas cap loose. With cap tight it runs hot more often. New water pump, hoses, degas bottle n cap, thermostat and no egr cooler. What in the world is my next step?

How hot? Factory gauge?

Is it puking coolant out the degas bottle?

Last coolant change? And what type of coolant?

Any mods to the engine?
