Although not impossible, it would be a real challenge to design a cooling system with a 180 degree thermostat that kept the car at 180-190 degrees max when outside temps are at 105-110 degrees. My point was that under extreme heat conditions a good radiator, water pump, high flow thermostat, fan and shroud are more significant than the temperature rating on the thermostat. I'm not very comfortable seeing the engine hit 215 degrees because I don't have much safety margin above that temp, but it does not hurt the engine.

Agreed. I used to work for Austin Speed Shop so I'm also familiar with the stupidly hot weather.... in fact its one of the reasons I moved back north

Now I'm cursing the rust.
