I don't mean to shoot several of us in the foot... but... what you quote from UK expert has potential to do so.

I've closely followed this thread. Along with you and some others... I too said that far as I know no matter what was to be "changed in the engine", i.e. type coolant, type oil, or for that matter water temp travelled in... That the thermostat would automatically correct coolant water flow to hold the engine at thermostatís rated temp. From what your UK expert mentions, maybe not?? First I've heard that.
