Otherwise, the hot water is kept out of the passenger compartment.
Allows A/C to flow withOUT having to pass next to the heated core.
Upper hose in pic is cooler water OUT of the heater core -

Excuse me for being slow and possibly repeating exactly what you said, but until 24 hours ago I knew nothing about how a cooling system functions. So my question is...
Does that shutoff valve you added go in the same location that a flushing tee would? Meaning, that if I were add a flushing tee this weekend when I flush my cooling system to make things quick, easy and not make a mess in someone else's garage... I could easily add a valve like this next summer to help my A/C run more efficiently? If its that simple, it seems like a no brainer to me.
I know people are opposed to cutting into hoses and increasing the potential for leaks, but the hose can easily be replaced if problems arise, i'm not too worried about it.
