From the Zerex FAQ:
Can you use Zerex G-05 in a GM Vehicle?
While one can use Zerex G-05 in a GM vehicle, Valvoline recommends that you use a GM DEX-COOL approved formula in a GM vehicle under warranty.

Personally, I would just stick with Dexcool. I've never had any issues with it.
Not sure when/if GM plans to change the factory fill, but as of '05 they still came with Dexcool.
