A manual control for an electric cooling fan would take care of it,but since I'm a 'flat-lander' the situations are rare.

Aerohead is right on this one and I have used this trick many times, with the heat on full blast and the windows down. Climbing these long mountain passes will make the coolant heat up. I did have a question for the OP. Did your car boil or steam? Are you sure it overheated? Personally, I don't get too concerned if the Scanguage reads 205º or even higher. Boiling is 212º at sea level and you have a 15 lb. pressure cap on you radiator that raises the boiling point even higher. Also, on most modern cars the temperature guage acts more like an "idiot light". You can see the actual temperature on the Scanguage and the factory temperature guage doesn't move. I trust the Scanguage to tell me what is really going on. But as always, buyer beware, it may be better to open up your grill block before you go to the mountains than to cook your engine.
