No arguments here. I just wanted to stress the point that a tstat's
rated degrees doesn't mean that the coolant temp. will never exceed
this rating (a common misconception). As usual, my use of caps brought
in implications that ruined my attempted articulate explanation :-)
I have similar results but I'm not quite sure how much of the lower temps
is a result of the 180F tstat or of the added water and water wetter
to the anti-freeze mix that I use. I did run just the 180 tstat for awhile
before adding more h20 and water wetter but the gas/rubber fumes
and open exhausts have scrambled my memory cells :-)
