The drain plug is located on the driver side, bottom corner of the radiator, facing the engine. Use a pair of biscripts or plyers to GENTLY remove it. Here is a strange tip that works if you are flushing your radiator: Use Palmolive automatic dishwashing detergent instead of flush cleaner. It will neutralize more rust and leave your radiator cleaner. Just remember to run enough water though it that there are not any bubbles left in the radiator or flush water.

most GM radiators have a peticock at the lower driver side corner of the radiator. Often hard to see from most angles.

I'm assuming you're trying to drain the radiator? Look up through the front wheel well on the passenger side. You'll see it on the back of the radiator.

It will be on the bottom right corner of the radiator under the hood
