I'm about due to flush the system in my 98 S-10 ZR2. All original cooling system (except lower intake manifold gasket replaced), running Dex since new.
Ive seen the Prestone white papers, and seen some of the application notes. It seems like the cor-guard may be a superior product, and in this application, I'm not terribly concerned about the 2-eha since I did the gasket and it's a known quantity and set of caveats in my old-school system.
Application notes indicate that unlike some other coolants, a chemical flush is not necessary going from dexcool to corguard or vice versa for full performance (at least my interpretation).
So, is there reason not to go with the yellow/orange cor-guard product over licensed Dex-cool? Seems like the car-guard stuff is a Dex clone anyway, but with some potentially higher performing additives.
I'm all for the ain't broke don't fix it concept, but just want to think this through...
Thanks!
