I had this problem before, my car would get warm sitting there but going down the road hardly warm. My coolant to water mix was like F**ked. I had almost all water i dunno how it didnt freeze. Changed to 50 50 an it was gravy all day everday. Hope this helps.

Is your car leaking any coolant? Are you going through any coolant? If no, try changing the thermostat.

Is it possible that at -15 the cooling system is too efficient and wont let the car warm up once its moving? This is why BIG trucks have blankets that go over the grill. To restrict sirflow over the radiator and let the engine get to normal operating temps during very cold weather.

Not with are cars, if you have to do this with a DSM you are only covering up and existing problem.

Sounds like a thermostat issue.... if working correctly it should restrict almost all coolant flow in the system....
