Where is the radiator drain plug on a 2003 Chevrolet Monte Carlo?

Answer

All the newer cars have a drain plug, but most of them are hard to find, are plastic, so they can break easily, and are a pain to get at. For these reasons it may be easier to loosen one side of the lower radiator hose to drain coolant. This is faster and does a better job.

Update: The drain plug is on the left side of the radiator at the bottom, just above the radiator lower mount. Use a 19mm socket to loosen but dont over tighten on reinstallation. You may need to move the black plastic shroud on the bottom of the car if so equiped to see the plug.
