That's good to know since my SS uses Dex and almost grabbed the wrong container the other day for the Jeep!Xpress said:Mopars like green for sure.
One thing you NEVER want to do is Mix Orange (Dexcool) and Green (Ethylene Glycol) coolants. The two substances react together to from a very thick gel that, in a nutshell, destroys the internals of your entire cooling system. You'd basically have to swap in another engine to cure the gelling problem.
I think the coolant type has something to do with the materials used. Our engines use a lot of cast iron throughout and Green coolant is what works the best. Orange coolant supposedly can rust cast iron out if any bit of oxygen gets into the system.
