If you drain the rad until it stops you'll get about 4 gallons out. I would plan on having atleast 3 gallons of coolant and 3 gallons of distilled water. The coolant is Motorcraft Premium Gold Coolant
The t-stats are a little tricky. you will need to remove the lowest vertical EGR cooler clamp and the bracket that is under it. The bracket is held to the block by one 13mm bolt that you can't see, that bolt will be tight (I've broken a socket on it before). Once the clamp and bracket are out you can access the four 8mm housing bolts, have a magnet tool handy to grab them. The black bracket that holds the housing down will need to be wiggled out first before the housing. Once the housing is out the t-stats will need to be depressed slightly and twisted out, it's not too hard, just awkward.
It's a safe bet that there will be some deterioration of the t-stat seals. Almost every set I pull has a tear or rip somewhere on it. Some just fall apart upon removal.
