FYI, I noticed in your'e pictures that you are running a Dorman degas bottle. Some of us have had problems with that bottle sealing with the cap. I had the collapsed hose issue and coolant leaking. I went back to a Ford tank and cap. This thread discussed the problem.

I ordered it with a new tank not knowing that the tank came with a new cap included, so after questions were asked about the cap I replaced it with the OE one.

I dont want to be the bearer of future bad news But.. those little pits on the back housing of the water pump on the motor is a sign of cavitation.
at some point someone did not keep up on the service of the coolant. you can not run just water in these trucks. some time in your future your going to have to change it.
one of those pit holes may open up and your coolant is going to go in the motor. Bad things will happen.. It is not uncommon on these trucks when the coolant is not kept up.
The motor will have to come out to replace it. for now run it and keep an eye on the coolant level. if you notice any coolant in your oil stop driving the truck immediatley.
im not saying it will happen very soon or anytime this year.. but please keep an eye on it..
You need elc coolant and distilled water.
That leading edge on the housing looks "chipped away" from cavitation. that can help cause air bubbles to run through the cooling system.

It came with some really nasty looking green antifreeze and a whole lot of gritty looking junk in it. I flushed it out per the method listed on this site and went from there. This last time I dropped the coolant it came out clean after about two years of service so the procedure worked like a charmIt has and will continue to run distilled water and Peak Fleet Charge which it about the only thing I can find locally that doesn't cost an arm and a leg. The simple fact of the matter is some things on this old beast are just not worth fixing any more due to the neglect by the previous owners. It will get filled up with distilled water and Fleet Charge to hopefully be the last time I mess with it. If things get any deeper I'm afraid the truck will go down the road. The condition of the body just doesn't warrant that deep of a repair.

I'm no expert on the 7.3 thermostats but I can't figure out how that longer one is supposed to fit where the shorter one was. Guys, is this a correct or updated thermostat?
Just curious, since you are now running just water so you can test things out, have you tried running without a thermostat to see if that solves your issue? Also, now that just plain water won't have the heat transfer capability as a 50/50 mix.

What I don't understand is how the short t-stat ever worked at all. The truck never over heated when I bought even while towing at max capacity. The 'new'(the long one in the boiling water, part house brand), tested t-stat is the correct length but could not have been closing the by-pass. There is no doubt in my mind that the OE stat solved the problem.

The truck is now running trouble free after changing out the water pump due to a leak an OE T-stat and a 50/50 mix of Fleet Charge. No more over heating!
