Subject: Re: Why does engine run cooler w/ heater, The real reason
No, I would say only about 13% correct. If the heater cores were AFTER
the thermostat, and said thermostat was closed, you would NEVER get any
heat out of them and hence the engine temp would be independant of heater
blowedness #8-/.
QED.
