You must not have an owners manual....see the "Service and Appearance" section for coolant info.

Dex-Cool. Be sure to thoroughly flush your cooling system to ensure you get all traces of the older coolant out of the system. Dex-Cool is supposed to last up to 5 years / 100,000 miles, per GM, but here's the catch. It may last that long; it may not. Several mechanics have told me that while Dex-Cool is a good coolant, it can suddenly turn highly acidic after a few years and left alone, will damage most of the metal with which it comes into contact.
