At the risk of being redundant; From my experience, anything marked as "OAT" (organic acid technology) will destroy gaskets and pump bearings in short order, no matter what brand, or marketing jingles. To combat this, I prefer to use the boring old green ethylene glycol based coolants that have been around before I was born. I mix these with plain old water from my well in a '50/50' mix.

With ethylene glycol coolant it is common to see gaskets and water pump bearings last well beyond 250K miles or more. With DEXCOOL I have never seen an engine last much longer than 100K before something is eaten away. In an Aveo, water pump bearing life is not a high point as they are usually replaced with the timing belt around 60K. You should probably be fine.
