water pump replacement question
So, I am knee deep in replacing the stock water pump on my 2000 F250 PSD with the International version pump. I just thought about something and would like some clarification from those that have done this job.
When I get everything back together and start refilling the cooling system with ELC, do I need to first put coolant directly down into the pump with the thermostat out and when that is full attach the top radiator hose, thermostat housing and then refill the radiator from the degas bottle?
My concern is that if I put everything together the way it is supposed to be, then fill the system from the degas bottle that there will be no coolant in the engine until after the thermostat opens up. If by some off chance that the thermostat is bad, or doesn't open until the engine is at operating temperature, I didn't want the cooling system to be dry.
Thoughts, suggestions, lessons learned?

Just by looking at things, I may have answered my own question.
I was originally thinking that the degas bottle fills the engine through the top radiator hose and through the thermostat, this may not be accurate. I think that the engine will have fluid in it by filling the degas bottle because the engine is fed by the lower radiator hose which eliminates the possibly of running the engine dry due to a pump swap.

I tend to over think things and dissect them to the lowest point possible. Thank you for the input and I do feel everything will work out well. I got the stock pump off and it was in very bad shape. The difference between the International pump and the stock pump is very drastic. More so than I had anticipated.
Looking forward to getting it put back together tomorrow and having the ability to change the filter in just a few moments and the peace of mind that the water pump should be good for years to come.

I did not do this because I had not read to replace the bolts anywhere within the dozens of threads I read about replacing the water pump. Although, everything is back together now with no leaks or issues after a 1 hour test drive. The pulley bolts went on easily and secured themselves quite well. I did put some red loctite on them to help with the securing process.
The hardest part about the entire install was getting the fan back on the shaft of the water pump. It is just an awkward part of the repair and I did not want to break the fan or drop it down into the engine bay.
I plan to put up some pictures in another thread because I also bought some parts from RiffRaff and then the pump from Diesel Site.

The tool was just like the one below, but without the wrenches. It was just the pulley holder with the red handle. I ended up using a large wrench of my own to actually spin the fan off. Worked well, better than I was anticipating really. There was no visible damage to the bolts for the pulley and the socket fit over them easily to during re-install.

I borrowed the tool from a friend at work who is a bit of a shade tree mechanic. He installed a lift in his garage and has 2 gigantic tool boxes with just about everything you could need.

One last thing... I hope you used blue thredlocker on those bolts!
They WILL come out if you didn't.
Don't ask how I know...

I did sir! I learned the hard way about using thread locker as well when I used to ride sport bikes in my younger days. I remember one time I was out on a ride with a couple of friends on my GSX-R 600 and the brake fluid reservoir literally fell off the bike and was hanging by the hose. This happened because I neglected to use loctite on the mounting bolt.
