Did you put a new cap on the radiator? Small as it seems, if it does not provide an adequate seal on the radiator, than the system does not get pressurized, thus keeping the boiling point around 212 deg. your engine gets way hotter than than normally. When sealed right, the pressurized system raises the boiling point to close to 300. thats how is works. If thats not it,(assuming it is the last thing replaced) than you might have either a cracked head/ head gasket/ valve guides, cooling ports, basic large dollar items. Lets hope for your sake the problem is still in the cooling system, before you look at the motor. If you take out the sparkplugs, you'll be able to tell real quick, rusty, burnt whitish-orange looking condition. Good luck

I had this same problem on a taurus and did all the things you did and found out after that the coolant reserviour bottle had a crack in the bottom of it

perform a pressure test on the cooling system,it will tell you if you have a engine overheating problem.
also look at your oil and see if you have water in your oil,test your exhaust pipe for signs of antifreez coming out of the engine.
