a good coolent
that can cause hot pockets and heat problems
switch to the green. make sure their is no orange in the system.
What's the trick to making dexcool work properly? Simple, don't let the system get low on fluid, mix with only distilled water, and DON'T wait 150K to change it. The only thing GM did wrong was recommending such a long change interval, IMO. Dexcool works just fine when used properly. I know people with newer GM cars that have 100K, 130K, even 170K+ miles on dexcool only motors for their entire life, and no leaks or cooling system issues yet. So what explains that if the stuff is so bad? It's all about proper maintainence, just like oil changes. You can use the best brand of oil avaliable, but if you let it run too low, or don't change it often enough you WILL have issues.
I'm not saying that dexcool systems *never* have problems, but what I can say based on personal experiance is that using the green stuff is no sure thing either, and anyone that thinks it is, is just kidding themselves.
Whatever you decide to use, just keep it changed often. Personally I would stick with Dexcool for an LS1 though.
My Camaro gets driven very little so my change interval is based more on time than miles.... I do a drain and refill each spring and a full flush once in a while. My Bonneville gets a system flush about every 12-20K miles.
