Where is the engine oil drain plug on a 2006 Chevy Malibu?

The oil drain plug on a 2006 Chevy Malibu is located on the bottom of the oil pan, which is underneath the engine. To access it, you'll need to get underneath the car using ramps or jack stands. The exact location on the oil pan itself might vary slightly depending on the specific engine (2.2L or 3.5L) but it will always be on the bottom. You'll likely see a bolt-like fitting there that is readily identifiable as the drain plug. Always consult your owner's manual for the exact location and any specific warnings.
