I've been knocked down drug out and left for dead
Is everybody still using Dex Cool anti-freeze in their GM vehicles, or have you switched over to the green stuff? The reason I'm asking is I have to replace the radiator in my 2011 Silverado 2500HD. I've heard a lot about people switching to the green stuff and would like to hear some input from you guys. I've also heard that you shouldn't switch. 
Thanks!

Thanks!
