I know to pull the plug on the bottom of the radiator, but what about the rest that's in the engine? Anyone done this before?

Yep.... I drained the radiator and then flushed with water ran engine with water runing and let it drip dry for awhile
then re filled. Easy

I just changed mine last week and found there are two drain plugs on the block, one on the drivers side and one on the passengers side. The one on the drivers side is towards the back of the engine right by one of the freeze plugs and is fairly easy to get to from under the truck. The one on the passenger side is a little harder and I didn't find it till after I got the antifreeze changed but, you can get to it through the wheel well on the passenger side. It's towards the front of the engine and it's also right by one of the freeze plugs. You'll get another gallon or two out that way but be careful because it really gushes out of there and if you don't watch yourself you'll get a face full of it.
