Fully Formulated Coolant and old radiator

[Wheel]

Is a 'fully formulated coolant' like Fleet Charge or Zerex Heavy Duty Green safe to use with an old copper/solder radiator ?
The application is my older (1989) Bolens/Iseki diesel tractor.

You dont want a Dexclone or Dexcool. Those will eat the solder.

That's what I've read. I was hoping to get the ASTM D1384 and D2570 results, but Old World Industries won't share them, they just state it will fit my application. I bet they won't come replace a hard to find radiator should it prove otherwise.

Both look fine, whatever is cheaper, get the concentrate. John Deere makes a very good coolant, Cool Guard II its availabile at the dealer. More info https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/1696012/1

Given the choice, I'd use the Fleet Charge, and not worry.

Well, IDK if this any consolation but, I am using Fleet Charge in the cooling system of the Firebird FORMULA V8 w/brass radiator for > 2 decades now with proper flush & change intervals. I just had the 39 yr old OE radiator recorded at my fav shop as it had sprung a small leak. It was about time, I mean, it is 39 yrs old. Still have the OE heater core and it's never been touched.

I meant to say, "recored"

I've been doing some research on my own, regarding the issues with OAT coolants and Solder, and it seems that 2-Eha is the culprit.


Dexcool, and Dexclones do have it, and it seems that nowadays they are the only OAT coolants that have it.

I am using VW Si-OAT in both my Fords and have no problems to report.

In addition to this^^^ above, I'd like to mention that my small leak was not in the soldiers or welds of the RAD, it was in an area that had acquired some rust/corrosion.

Wasn't 2-Eha also a suspect in being incompatible with older gasket materials ?

It's been reported various times to swell seals and gaskets
