I bet you live in a cold area.... I'd like someone to try putting a piece of tarp or plastic trash bag over the grill area of the car to keep the moving air directly off the radiator. If you've ever watched Ice Road Truckers, the big rigs all have some type of cover on the radiator grill to cut down on the area getting direct air.
