Another vote for Peak 10X "concentrate". Long service interval OAT AF, no 2eha. That latter piece of information makes it same as Mopar OAT. However, cost of 10x much more reasonable. In this case, I'd thoroughly flush system first.
I'm NOT buying into Prestones claims. I think it's all marketing and numbers. I might believe if it wasn't a Universal coolant.prestone 10/300 is the undisputed king of universal coolants
Ford uses Prestone Cor-Guard as OE fill now - as Motorcraft Yellow. If Toyota says their pink coolant is good for 10 years/150K from the factory and VAG(VW/Audi mostly) their coolant is good for “life”, barring any cooling system parts replacement, I believe it.I'm NOT buying into Prestones claims.

Oh the 10 year OAT has been plenty problematic with heater core stuff. Journeys, rams, GC, 200s.I haven’t seen anyone complaining of issues with the Mopar OAT, but my Mopar interactions have been mostly limited to the LX car forums.
Even still, hard to imagine the coolant itself causing clogs in the system while still within its service life. Once it’s outside its service life, sure, or if it were mixed with really hard water during fill, but the factory fill OAT is mixed with distilled water and shouldn’t be causing any problems.
That’s the reason why Ford switched all their Dex-Cool stuff to Prestone Cor-Guard. There was a TSB stating to do any repairs needed including an updated heater core then a flush and fill with Cor-Guard before Ford switched gears and used it for everything that took orange.Oh the 10 year OAT has been plenty problematic with heater core stuff.

the original g12 and basf g30 g33 and g34 (gm europe dexcool) were all sebacate only formulasThat’s the reason why Ford switched all their Dex-Cool stuff to Prestone Cor-Guard.

VW’s G-12/13 series of coolants were also close to Dex-Cool but it only used 2-EHA alone - no benzoate/sebacate/adipate. I wonder what Mopar’s new purple/pink OAT is using.
That’s more a Mercedes move than a Mopar one. Mercedes also switched to G-48 in the mid-2000s and then to purple G-40 in the late 2010s.I've read about Chrysler putting some sort of slow release silica packets in the reservoir tanks on the vehicles with the purple OAT coolant. Is that something I would want to do with this old truck when putting it together you think?
