Check out the 99' to 03' 7.3 forum. There is plenty of info for your engine in there.

There are a lot of coolant threads in the 7.3 forum with instructions, but first, are you keeping the gold or switching to the red stuff (ELC)? Just curious, and the flush technique is a little different when changing. Secondly, since you're opening the system anyway, think about a 203* 'stat & billet housing from dieselsite. Well worth the bucks, and your truck will run better with the hotter 'stat.
