We prefer to run our engines on the cool side. Not 140 cool though.
Technically it's impossible for an engine to run 140 if you're running a 180 stat because it won't even be close to opening. A stat forces the engine to run at or near it's rated temp give or take about 5 degrees. The only thing possible in this scenario is the engine running way "above" the rated temp which means you have other issues.
I'd like to see the temperature measured with another gauge and/or shoot the hot side with a temp gun. Something is off.
