I believe they eliminated the drain plug and your going to have to drain the radiator by disconnecting the lower radiator hose. GM started to eliminate the drain plugs for cost savings and to eliminate the drain plug O ring failure when removing it and placing it back in.
If you do have one, it's located on the driver's side at the bottom of the radiator fan side. As mentioned, there common to fail once removed and 85% of the time. Your going to have to replace the drain plug if you do decide to drain your radiator by using that method.
Good luck and be safe.
