No pics, but it's on the driver's side on the middle of the engine block, right above where the oil pan bolts to the block. Just like right above the oil pan, and you should see it.

There is also one on the passenger side right under the starter. If you have a fuel injected car it's where the knock sensor screws in.

I replace pipe plugs in block with drain petcocks. Cleaner engine swaps when the block is emptied of all coolant.
