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.
