so then, why when a car is running hot, do you " race" the engine, thereby speeding up flow? wouldn't you want it to idle, so the coolant spends more time in the radiator?


see thread in the race section. "time in the radiator" is an old wives tale. you need coolant flow, air flow, plus adequate radiator size to maintain cooling parameters.

This is one of my 3 most favorite myths though. Neat thing about it is that it will NEVER go away.
