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. :dunno:
Thanks!

In the newer trucks (2007-on) we have kept the DeathCool, and have had no issues. I am not talking just about my rigs, but the many I have bought and maintained at work. We have some Dmaxes and 6.0s with over 200K on them, and have kept in in there with no issues with leaks or pump issues.

Thanks brother. I'll more than likely continue to use it. I just wanted some thoughts from you guys and what y'all are using.

Nothing wrong with sticking with Dex. Nothing really to gain by going to green either. No issues with Dex in all our company vehicles

The biggest issue with any coolant is solids drop out due to coolant age or overconcentration. We see so many pumps and radiators with the green goo, or the orange goo, or the red goo and it starts eating radiator joints, etc.
Change your coolant, people! Is what I want to yell at some of my customers when they complain about the life of one of our products.

It has GOT to be one of them most overlooked maintenance items, period.

I plan on flushing the system when I get around to doing this. :cheers:

Half way between here and there.
Nothing wrong with Dexcool. I changed over to AMSOIL's coolant. One because it is ecofriendly so if it did spill no harm to our furry friends. Plus I use what I sell. Not saying you have to.

So for now my 2002 Silverado has AMSOIL coolant as does my 2014 Cruze diesel. When this summer rolls around I'll change over my daughters 2012 Cruze and at the 5 year mark the wifes Suburban will get it as well. I got some time on the new truck. :)

Coolant and brake fluid, lol. Both only get changed when there's a leak.... And usually only topped up.
