I had a curious observation about a month ago, I was idling the car so my son would stay asleep while my wife was shopping. Anyway, the heat was on low and the radiator fans didn't come on once in a half an hour of idling. I was watching the fuel usage on Torque and it was using .225 - .250 gph, I imagine if I had turned the heat up it would have overcooled the engine.

In contrast, the intrepid had a smaller engine and used about .450 gph and I could run the heat full blast and never cool the engine.
