Hi, I thought I would make this a separate thread from my other one
about a decent 12 volt portable heater. Now, that the in and out hoses
are pieced together in a bypass for the heater core leaking, I was
wondering.....what if later this summer I ran some Barseal (?) or
Stopleak just through the heater core via the ins and outs with some
kind of looped setup?

So, I guess what I am asking is how I could attempt this. I am
assuming I will need the proper heater hose sizes, some additive that
will do the sealing....but how would I get this stuff flowing in and
out and hopefully plugging up the leak? I think this might be a decent
alternative as it wouldn't affect the engine, radiator and all
connecting parts. I hear that is the main reason why most don't back
using those stop the leaking products. Maybe this is an avenue to
explore. Please get back to this thread if you have an idea how this
could be accomplished or have followed through on another method that
might work. Thanks for the help in the other thread and assisting in
this one, psongman
