Coolant
I just purchased a 97 F350 Dually with the 7.3 Turbo Diesel. This truck will be used primary as a tow vehicle for a RV. It has a verified 98,000 miles on it. Since the wife and me are planing on some extended camping trips,I want to be sure all the maintenance is up to date. I had the trans serviced yesterday with a fluid change and filter. The supplemental owners manual says to change the coolant at 50,000 miles. Since I have no way to know if this has been done, I decided to do this myself. Manual says it holds 22 qts of coolant. I took drain plug out and let it drain for about two hours. Manual also says to install 4 pts of coolant additive FW-15 which I did.When I started back I put one gallon of 100% antifreeze and one gallon of water,I then put another gallon of antifreeze and tried to add a gallon of water,but it will not hold anymore. This is about 12 qts on coolant and water. What gives? Does it have a bleeder screw somewhere? It only held about 1/2 of what manual stated.

The 22 qts is total capacity of engine cooling wise. As if it were new. Check out the link below. Its not OBS specific but you'll get the idea.

Pete has you on the right track. The link he posted is an excellent write up and is the one I followed when I flushed my system (and will use again).
While you're at it, have you thought about a coolant filter bypass install ? It's not a difficult install, is not expensive and will filter the junk (mostly casting sand) out of your coolant giving your water pump a longer life.

I didn't have the coolant handy when I replaced my radiator, but my new radiator holds 7 gallons. Which is about 29 quarts. Which I filled with water as a temporary fix. I'm still filtering out the crap from my old radiator, see my pictures.. so I definitely need to keep flushing my system before I add expensive coolant that gunk.

Congrats on such a low mile 7.3!
Finding a good woman is like trying to find a low mileage 7.3 powerstroke, hard but do-able.

Alex posted a nice setup. I couldn't afford it at the time so I went with the following. Remind yourself to check the SCA. You can add with a filter change.
