The factories have dumped billions of dollars into engine research. Modern cars run around 200 degrees. They are more efficient and pollute less at those temps.
They put much more time and money into it that I ever will by second guessing them while standing in my driveway.

I'll defer to the engineers.




YES...new cars run hotter. My silverado runs at a constant 210...it's designed that way. 60's cars were designed to run at lower temps. There were no smog pumps, or other rubbish back then. The engineers designed them, that way...back then..like comparing apples to oranges
