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.
