I tend to disagree with you
If the t-stat stayed open all the time the engine would over heat. Granted
it may not close completely but never the less the coolant needs to stay in
the radiator for a while to cool down, Hell if the thing stayed open all the
time why bother having one in the first place.
I tell you what . Take the cap off of the radiator let the thing sit there
and get hot, watch when the stat opens you will see the water circulate then
it will stop when it closes.
Trying not to be an a** just telling it like it is
IMHO
