brian...
i'm curious about your response.. years ago when i was still living in "the hills of w.va." taking the thermostat out of a car that ran hot was always the first "remedial" action - and always was good for at least a 10 degree temp drop. back then, i believe there were two thermostats - a 160 degree and a 180 degree. we used to call them "hot" or "cold" ones. it was common when removing the thermostat from an overheating car to find the thermostat to be rusted and stuck in place not allowing the baffle plate to open under temperature. by your theory, running with no thermostat would result in the car also overheating. but i never found that to ocurr once i removed the old rusted thermostat. in fact, a lot of cars during the summer would not have thermostats and they would only be reinstalled "when it got cold" so the heater would work!! do you have more information on your view?
are there other FABO "experts" out there that want to join this debate? please no angry responses... !!
