Where is the engine coolant drain plug on a 2000 Cavalier with size of 24 liters?

There's no single "24-liter" engine size for a 2000 Chevy Cavalier. The engine size affects the location of the drain plug, and the Cavalier offered several engine choices that year. The coolant drain plug's location also varies slightly depending on transmission type (automatic or manual).

To find the coolant drain plug, you'll need to:

1. Identify your engine: Check your vehicle's documentation (owner's manual) or the sticker under the hood to determine the engine displacement (e.g., 2.2L, 2.4L).

2. Consult a repair manual: A repair manual specific to your year and engine will show the exact location of the drain plug. These manuals often have diagrams and photos. You can find these online (like Haynes or Chilton) or at auto parts stores.

3. Look under the car: Once you know the engine, visually inspect the engine block's lower section, usually near the front, toward the bottom of the radiator. The drain plug is usually a bolt or a cap. Be aware that it will be hot if the engine has been running recently.

Without knowing the exact engine size, I cannot give you a precise location. Attempting to locate it without proper information is risky; you might mistake another bolt for the drain plug. Use a repair manual for accurate and safe information.
