has anyone actually experienced a problem or difficulties with modern glycol antifreeze in older cars? the oldest everyday driver i had was a 49 kaiser about 6-7 yrs ago... even that was happy with the good old [new] 50/50 mix... what i do run in everything now [since i get it free and would cost about $375 per 5 gallon pail] is the CAT red lifetime coolant, better than dexcool, i've been using it in everything from my most prized survivors to the daily beaters [59 fury and yes, a turbo volvo] with no problems and excellent hot weather low engine temps.
another nice bridge product is Crown forklift hydraulic and brake fluid... far surpasses the qualities of modern silicone brake fluid... i run that in my 51 buick, 4 57 and 5 58 plymoutjs with everything from stock total contact braking to wilwood 4 wheel disc setups [and in all my later GM muscle cars as well]
and dont believe a machinist that tries to sell you on hardened valve seats.... all the old time until the 35yr veteran range of machinists agree the lead lacking in fuel isnt going to kill an engine... and i've personally time tested, raced, and pounded enough lead era cars in the modern unleaded world.

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.
