Random question: I just started looking into the AC/heating system on my car and came across the water control valve. Interesting design concept, I must say. So here's the question. If this valve shuts off the coolant flow through the heater core when the AC is turned on to maximize air cooling, isn't it reasonable to think it might lead to over heating? It seems that when external temps are the highest is when one would run the AC. So, high external temps and no coolant flow through the radiator and/or engine block would seem to be a disaster in the making.
I haven't had a problem, but I don't usually run the AC either. And, it's not like I don't trust the fine engineers at FOMOCO, but still. Am I over thinking it? Inquiring minds want to know.
