Ed,

I’m with Tracy (use high quality glycol & distilled water), except for some possible RTV that might break free and get stuck in one or more of the radiator tubes.  Seems a good backflush would remedy that.  Next time I have my cooling system apart I might take a peek inside the radiator and see if there is anything blocking the tubes.  Corrective action would depend on what I find.  It wouldn’t take very many blocked tubes to push some of us over the edge.

Perhaps we could fashion a quickly removable filter and patch it into various systems for a while just to check what it picks up.
Like, I wouldn't have thought it possible to block up a whole damned radiator ... Jim S.
