Re: [FWDLK] Living with modern anti-freeze products



Thanks, Paul!

Ergo, when in doubt, pure H2O works fine, in a non-air conditioned FWDLK'er, as originally
designed, and tested by Ma MoPar.

I'll bet that not many people know the real intended purpose of that radiator 'drain' tube--- to relieve excess internal pressure, rather than as a coolant-fluid drain pipe.

You did answer your own question, Neil, glycol-based anti-freeze was used year-round even back then. It was required in A/C cars, but useable in any. And ethylene glycol raises the boiling point as well as lowering the freezing point.

The PROBLEM TODAY as I understand it is that antifroze is still mostly
ethylene glycol --> BUT <-- the additive package the makers use and
put in with the ethylene glycol before we buy it in the gallon container
is what makes the modern stuff today a problem with the older car cooling
system and PRACTICES.

our stuff stayed the same, but the game changed!!!!!
