The thermostat will not effect maximum operating temperature. Unless
you have one hell of a cooling system, or live above the artic
circle.....
It will only effect the rate of initial temperature increase of the
coolant. If we compare a 165 degree thermostat vs a 185 degree
thermostat, the rate of increase will be the same for both up to 165
degrees; after that, the 165 degree thermostat will open and allow for a
slower rate of increase than the 185 degree thermostat (which of course
will remain closed until 185 degress). But then I think Paul H and I
have had this 'discourse' before. If I'm not mistaken he does not agree
with me on this point. Ya out there Paul? It's time for your point of
view.
