I run a 160 deg T'stat in one of my cars and a 180 deg in another. With both, especially the 180, I have noticed the temperature swings Jim mentioned even though I have drilled another 2 X 1/8" holes in it. I see the sense in the bypass hose but I like to keep my engine bay looking resonably original. The T'stat is invisible and the hose not so I wonder about drilling more holes in it.
Your thoughts?
