Motorcraft Yellow replace both Specialty Green and Orange, right?

according to ford, yes.

as for the Chemistry... I'm seeing on one site that the yellow is POAT, and on another that it's HOAT.( that one,which I would like to trust, as it's a link from a test lab at Stanford University, unfortunately when i try to access it, I just get a "FORBIDDEN" page but the Preview text under the Google Link says
"Sep 5, 2025 — Motorcraft Yellow Coolant is formulated as a concentrated, long-life antifreeze that incorporates hybrid organic acid technology (HOAT). This ...")
Lots of Folks have said that the yellow is just Prestone with CORGUARD..

Motorcraft yellow is a pHOAT. You’ll be fine with that or Prestone Cor-Guard.

The older orange fill is a plain OAT, it’s just Dex-Cool. The gotcha is gold/G-05. While Prestone says it can mix with it, I would advise against it. It’s a SiHOAT but with a dose of borate to prevent cavitation in wet-sleeve diesels. It was approved by Mercedes, CAT and Detroit Diesel as well.

Thanks to all for all the help.
Ordered a New Radiator from RockAuto RAD64 at $. 230.95 (shipping included). Today I check and is a little cheaper.
Each Gallon of Coolant at $. 11.00. I bought 3 just in case. Finally I decided for the Valvoline Zerex Asian Green.
The old radiator replaced (from stock 2011), just touch some of the plastic parts and broke in the hands and some corrosion.

Yeah, BTW POAT is a Hybrid. P=Phosfate is Inornanic + OAT= Organic
