did my flush exactly a year ago with dex cool in the system now. is anybody else runnin this stuff? is it better or worse than whats recommended? i was thinkin about switchin to the zerex next summer but just trying to collect info now

 

Dex cool was designed for gm engines and is crap. If it gets any air in it the solution ionizes and it will cause corrosion. Use the good ole' green stuff its cheaper and your engine was designed for it. Now remember if dex cool and the green mix it creates a snot like substance that can clog water jackets so the system must be clear of one before adding the other.
