Where is the oil drain plug for a 2001 Chevy cavalier?

The oil drain plug on a 2001 Chevy Cavalier is located on the bottom of the oil pan. The oil pan is the large, somewhat flat metal tray underneath the engine. To be more specific, it's usually near the front of the oil pan, but you'll need to get under the car to see its exact location. It's a fairly common bolt and is usually easily accessible. Be sure to consult a repair manual or online resources specific to your engine type (2.2L or 2.4L) for a diagram or picture, as the exact position might vary slightly.
