I turn the tap off in May and open it up late Sept, I couldn't imagine driving with the heater core live in the meat of
the summer.  Cabin heat (even when the engine isn't reading truly hot) is the only thing that would make me consider
selling mine.  If the engine is getting hot I stop at a bar until it and I are cool.
