The old school green stuff - where to get cheap

AMAMs have unpredictable chemistry eg. some of them even contain the 2-EHA plasticizer
I've ordered Zerex green off Amazon, but even O'Reilly and AZ have conventional green. The Zerex formula is still a silicated and phosphated coolant but it also has a touch of OAT to give it a longer life.

All of those are Asian phosphated silicate free formulas. While Toyota Red isn't a true "super long life" coolant it qualifies as one. Toyota Red uses sodium benzoate as the organic acid component(Honda and Subaru Blue also use benzoate), while Toyota Pink uses sodium sebecate or sebacic acid for the organic acid. They will mix with each other.

FWIW Prestone All Makes All Models says it will work with any mfgs guaranteed on the bottle. It is prediluted.

they're talking about death-cool aka dex-cool clones, which the prestone amam and several others are.

I use the plain green stuff thats full strength at Walmart. Hard to beat the price.

Last time I looked at SuperTech antifreeze bottle more than a year ago, it listed 2-EHA which is typical for a Dexcool clone. If so not the best if trying to avoid Dexcool.

sw99 - That's not "conventional" coolant. That's a Dexclone. Note the circled portion:
..... Sodium 2-Ethyl Hexanoate. 2-EHA. Dexclone.
..... Sodium 2-Ethyl Hexanoate. 2-EHA. Dexclone.
Good to know, thanks. I really never worried about it but then again I do yearly drain and fills so that might be why. I have never had any coolant related issues.
At one time I think supertec had a true old school green, but turns out that
Since I have had my 1950, even with the original engine, I’ve used autozone brand original green, which boasts the fact that it’s old school and concentrated.
Turns out the reason I had to add coolant (which is my, inherently, I started this thread) is because over tne winter, my 68 year old radiator gave up the ghost. Being that I have a replacement aluminum one, it’s already 1/2 way installed; modifications are done. Before I fill it, is the green an appropriate coolant for an aluminum radiator?

I've been doing 10 year coolant changes with both my BMW and mt Ford. No problems so far. Had both since new
