Chasing this cooling issue for months

I drive between high desert and low regularly.
I leave my house and it's 45 degrees out and when I get where I'm going it could be 110 outside.
I said before that I wanted to drive this car through hell itself and not overheat.
Just another case of "be carefull what you wish for" it seems.

Why is that 195 thermostat passing coolant at 175?
Seems to always go back to that to me.


Bigger isnt always better.
