Is there a GM approved coolant to take the place of Dex-Cool, or has this clogging issue been resolved?

Years ago there was talk of GM's Dex-Cool clogging cooling systems. If it still clogs systems I do not want to use it.

    You use whatever you want. I heard people say it clogs & others say its corrosive. You use what you wanna use. Even though there are only a very few plants that actually make coolant & GM isnt the only manufacture to use it either. If you keep it maintained, all coolant will last
