Ok, before the my buddy/mechanic/uncle's brothers friend said............
Why did DEXCool get the name DEXKill? These opinions and discussions are about a decade or two late and no longer relevant. Do the research in the chemistry of DEXCool and how it was improperly rolled out.
GM screwed the pooch and initially started using it in vehicles (1998-2000ish timeframe) which were still vent style cooling systems; specifically or example case the GMT400 platform. That was causing the coolant to become acidic and that's where the problem stemmed from. (NOTE: there are/is countless articles, videos and reference material out there if you look for it.)
Once GM went to closed coolant systems the problem disappeared. Only took a bunch of chemist and engineers to figure it out.
How do I know.......well working as a tech, talking to GM Master techs and doing that crazy thing called research. Our culture here in America needs to friggin change and stop taking everyone's word on everything w/o researching it.
But, I read on the internet that...
