I have a 99 f350 xlt 4x4 and I just replaced the waterpump and did a coolant change. I dropped the lower radiator hose and drained out everything through there as much as possible my question is that I poured in 4 gallons of concentrate but I only managed to add about one gallon of water and now the water doesnt seem to have circulated at all yet and I have been driving it for about a day and a half now. Temp gauge marks normal and when I squeeze the top radiator hose coolant flows back into the degas bottle from the bottom hose. Degas bottle still marks full from initial fill up. AND If I have the short thermostat instead of long what would happen? Would that cause no flow of coolant?

 

And also the upper radiator hose is was hot but not the liquid in the bottle

 

Wrong thermostat or stuck thermostat.

 

Additionally, you may be running a 70/30 ratio or higher. Figure you have 4 gallons of concentrate, one gallon of water, and 3 gallons of whatever you had previously. Might want to measure the fluid and see where it's at. While you might get away with a 60/40 ratio in colder areas, I would guess your coolant to water ratio is way too high.
