Coolant flow

False information [ post # 21 ] is still being given about t'stats, this time the Stewart Components Hi flow stats [ same as the Milodon & Mr.Gasket ].

The temp stamped on the stat is the opening temp, not the fully open temp as claimed in post #21. Fully open is another 20-30*. A 180 stat is not fully open until 200-210* & it an industry standard for t'stats. I have tested many of these over the years, using a digital thermometer.


Ok. Maybe where the toilets run backwards. I can run out and grab my 160 degree thermostat and drop it in water and watch it. At 160 its WFO. Just like every other Stewart Components thermostat I’ve tested.

There is no way my engine (or any of the engines I build and tune) could run at the rated temperature IF the ******* thing isn’t full open until 20 degrees above its rated opening. Explain that.

If the thermostat is rated at 180 and it STARTS opening at 180 (which means it ain’t open very far is it?) how do you have enough flow to maintain 180? You can’t.

Stop screwing up threads with bad information.
