How to turn your heater core off and on in the cab.

I like this idea. I was considering this to help out my A/C during the hottest months. My A/C box doesnt bypass the core all the way when set on max cool, so it's marginal at best, even though the whole A/C just got overhauled. Definitely better than before though.

I was considering ball valves to shut off the core, one or two. I carry fittings to bypass if needed...I had to bypass a hose today as a matter of fact down by the APU outside of Mcdonough.
