Pretty sure that you don't want to go mixing the Dex with the green stuff either...if you did decide to switch you'd really want to flush the system really good first.
just change it when it says too thats all i changed mine and it was fine no "clumping" or "gelling" at all and it runs fine Dexcool all the way

No dont go green, stay with dexcool, obviousley gm put it in there for a reason, and bullshit it dont clog anything, i just did a full coolant flush and there were not any corrosion or whatever they say comes out , gel or something. BS stay with dexcool.

OK, this is getting sickening. Dexcool is known to gel up and turn to sludge-thats not an opinion its a fact. The truth is, if you flush either type at 50,000 miles you shouldn't have any problems. But why take the chance? The green stuff is the better choice. And that info comes straight from my mechanic who happens to be an ASE master technician. I would trust him with anything, he is the best. Did I mention I am my own mechanic?

I do know there were worries in the GM camp that the 4.3s didn't like the new dexcool stuff much and the 8.1s didn't either. Even service bulletins. My dads good friend is a regional service manager for GM and even said it was ok to run the green stuff in new vehicles if the dexcool was flushed completely. It should also be noted that Mercedes Benz doesn't use long life stuff why? hum food for though. Maybe their engines are too low tech and they don't really know anything about engineering so they go with the green stuff. Lets face it, just like 15K mile oil changes, 150K miles between coolant is tooooo long. if you flush once every two years you'll be fine with either i'm sure since you'll always have fresh coolant.
My .02 cents.

Do what you want. If there was a problem with Dexcool.......GM would have already pulled it and began using something else. They have been using it for quite some time now.
By the way.....there are a lot of ASE certified master techs out there.
That is just one with his own opinion.

Your not going to do a flush and make a gasket stop leaking either.
The Dexcool coolant has additives to prevent corrosion of the aluminum parts that the coolant flows through. Like the heads and any other aluminum parts.
So your mechanic knows more about coolant types than GM huh?
GM didn't just decide to switch to a different coolant for nothing.
Go with Dexcool!
You should flush your coolant about every 60,000 mi.
Tranny fluid needs changing every 24,000 mi. Not a flush. Just drain pan and change filter. Not all the fluid is changed, but there is no need to replace all of it.

I know people are quick to state the negatives about something new because people are affraid/resistant to change, but I just stated a 100% factual occurance. I gave my opinion that deposit that I saw in the system might have been impacted in the joint and swelled causing the leak. I have no proof of that but I figured any competant man could have understood what I meant. And yes, I called you incompetant due to your response. If you would like to respond this please do so to via PM or call me at 256-476-2598 and I would be happy to discuss in further my experiences.

I use the green stuff
its worked for years in many engines with aluminum parts
as far as GMs reasoning
who knows maybe the same reason they put plastic accumulators in a 4L60
Ive also heard that tap water is bad with the dexcool
so if you were to use dex Id throw some distilled water in there to play it safe
