IIRC, these cars run about two-three gallons of water in the cooling system. I have noticed that when it is cold out, the car heats up pretty quickly, but then, as I'm driving, cools down to barely warm. This implies to me that the thermostat eventually closes when the car is cold, but otherwise runs stuck open. So, for my fellow GTV6-owners-who-drive-in-cold-weather, what is the approximate normal water temperature operating range? BTW, the fans do kick on when the temp gets above about 175*F. Also, the air temps were about 35*F this morning, and the gauge was riding the 100-110*F area during most of the time the car was moving.
