Google'd Dexcool
I was doing a search one here to see if I can flush my eng. and rad the same way as i did my truck (little more cautious with the vette) and of course the anti-freeze to use is dexcool.
So I typed in google dex-cool to see where I can buy some (Dealer and..?) And first few hits were not in favour of dexcool. Something along the lines of ruining gaskets,seals,water pumps and goopyness?
I didnt find anything on the forum about it yet though.

Unless its old newsGM is still using it as is Toyota. My personal opinion is that if you change the DEX-COOL every 2-3 years you will not have any problems. At the same time the "green-stuff" has given outstanding service for many years when changed regularly (24 months for me) so you should have confidence in it if you decide to switch. The most important thing is to change it regularly.
Good luck... GUSTO

This is correct. Also, one of the reasons that DEXCOOL had problems was because early on aluminum heads were mixed with cast iron blocks. Then if air got into the system the electrolysis went wild and the result was a thick brown goo. Not good for cooling.
Even though there still exists applications where aluminum components are mixed with iron, the problem doesn't seem to be as bad because of the education process in the automotive world. Mainly, the sealed expansion tank ystem vs the old style vented expansion tanks. There isn't as much of a chance of allowing air into the actual cooling system provided the expansion tank level is maintained in the proper range.
However, one should exercise great care to locate and fix any leak in the cooling system as this is a potential source of air ingestion into the system as it cools and the resultant contraction of the coolant may draw air in through the point of leakage.
