My truck has been running cold since I got it, so I decided a couple of weeks ago to pop the thermostat housing off, suspecting a bad or missing 'stat. Sure enough it was jammed wide open and the housing full of crap. One quick thermostat and new housing later and we're running nice and warming up faster.
Pics are in my gallery.
Btw, there was no coolant/antifreeze in the system, just rusty brown water... so that's obviously what caused it. Thermostat was abt $5, housing $8 at local parts store.

Either your thermostat is not there....or stuck open.
where is the coolant level on the degas jug?
What gauge are you using to read temp....and did it read roughly 190 before flush?

Well we figured out the problem,the shop that flushed my cooling system out had replaced my thermostat with a STANT thermostat because a FORD stat wasn't available.So took the truck back and he got a hold of a FORD thermostat and while he was replacing it he broke off the nipple of the radiator on the little hose that runs from the radiator to Degas bottle 
.In the end the he replaced the radiator with a brand new one 
at no cost to me and everything is running the way it is supposed to! I'm glad that's over with and like what everyone here's has said "always use Ford OE replacement parts!"
