Ed...
I agree there seems to be a contradiction of information somewhere.
The information I based my statments on came pretty early on in a week long class presented by AC Delco and after that demo they had my full attention for the rest of the session.
Their position was all things being equal (ambient temp, load, fuel rate etc) reducing the operating temp of the coolant by going to a lower thermostat did not result in more heat being rejected by the engine. It did,however, result in more cooked seals and gaskets as well as increased emissions.
A poor old mechanic don't know who to believe anymore, but if I can't feel a performance difference in the seat of my pants, why bother with changing something that was engineered to perform to a certain standard.
Sorry, I didn't mean to start a big controversy, but only to pass along some info that was presented to me a long time ago.
