'98 2.4L: Where is the engine block coolant drain plug?

[jonnythan]

I've poked around where I can see on the engine block and can't find anything I could really say might be a coolant drain plug.

Any tips on finding it, and what does it look like?

Anyone?

back side of the engine, lower center.
Should have a square hole in it to attach a ratchet and remove.

Remember to use sealant on the threads when you reinstall it.
