The water valves are tough to service even if you have the parts to get it done..Pay close attention to the O ring sealing area between the valve and core it needs to be perfectly round and smooth...Some will give up trying to keep it from leaking on the floorpan and do what you have there totally shutting off the water...In my experience most times it's the valve being the problem and the core is usually good hopefully that's your case...I get the whole heater box kit from DMT and refinish the blend doors for new sealing foam and smoother operation while I'm in there..

Thanks for the info & I'll be sure to check the sealing area & O ring. Its gonna be a pain to remove the box but hope its easier than I think. Not much info on the early B's out there.

It's been a looong time now, but having had about 17 of the 64 Plymouths, I used to have recurring problems, and the control valve was on that list.
Drain it down, or just wire the hoses to hang above heater level, vise grip, etc.
IIRC, removing the radio first may have eased clearance problems, but for the most part it is a pretty easy job, once into it you will have it out in short order.
I'm with the other guys on the shutoff, My take on it is that it was being used to control flow thru the core, as a shutoff in one line won't stop coolant from occupying the core, so the valve probably isn't (wasn't) leaking either.
And, may I say, that is a great looking engine compartment, most of mine were much worse, (and much newer!) back in the day ... color is the same as VT state police used, had a few of those too.
It takes gasoline to interest me.

A huge thanks for all the info & advice and I'll start on it today while the seats are out to the upholsterer. Its a no rust survivor & even have the orig certicard. Orig 383 runs great but has some blowby issues from a couple of cylinders (broken or stuck rings), so it'll be coming out soon for a stock or stroker rebuild.
