Hello All
I live in the Midwest. Years ago I read an article in the local paper that advised that in the winter, when you first start a cold engine, you should keep the temperature control for your heater turned all the way to the cold position until the engine had reached it's normal operating temperature. Then, at that point, you could turn on the heat in the cabin. The reasoning given was that you didn't want to divert heat from the engine until it reached its full operating temperature.
I've pretty much followed that advice based on reading that one article years ago. But reading some of the posts in this newsgroup got me wondering if I am following one person's well intentioned, but misinformed advice. . Is there a sound mechanical reason for keeping the heat off in the car's cabin until the engine is fully warmed up?
Thanks.
