The oil drain plug on a 2005 Chevy Cavalier is located on the
bottom of the oil pan, which is the part of the engine that holds the oil. To be more precise, it's at the
lower front of the engine, generally near the center but slightly offset toward the driver's side.
You'll need to get under the car to see it. It's usually a relatively easily accessible bolt. However, always consult your owner's manual for a diagram and specific instructions. This will help you avoid damaging anything.
