Default Engine Block Drain Plug???

Where exactly is it on an 99-04? I read in the Haynes manual there are two, but I can only find one that resembles a block drain plug on the driver's side right behind the freeze plug. I'm just wondering b/c I'm flushing my fluid and was going to drain the block, but wasn't sure, so I just did the radiator.

i just wanna know for future reference if i have to take off the lower intake or something to do some work. here's what i came up with as far as photos go. i tried for about 1/2 hour to come up with a safe way to get it off and then just gave up and finished the flush.

Itried a boxed end wrench. It didn't work out for me so well. I jerry-riggeda 3/8 ratchet, 3" extension, and reversed a socket(of the right size)to fit over the end of the extension so that the 3/8 square holeof the socket fit perfectly over the plug. AfterI tried this a few timesI saideff it and just did the normal flush. As you can tell, the thing is goin to be a bitch to get off if I ever have to...... and after all this, I hope that this was the drain plug in the pic. (my orig. ques) lol
