I really think that the running temp should be pretty close (within 5-10F)
to what thermostat temp you have installed.
If you are running at 212F and you have a good 180F thermostat then
it means that your cooling system is marginal and can't keep up.
This is assuming your temp guage is reading correctly.
I used to think along those same lines you guys indicate.
A long time ago I put a 160F thermostat in in a vain attempt to bring that
"over 200F" temp down. It didn't make much of a difference.
After I had the radiator cleaned out last year guess what?
It now goes up to 165F and it holds steady! Imagine that.
Epiphany.
Now I have to go back in there and put a 180F thermostat back in.
