Just to be clear, prior to the flush and subsequent tank change, it did not overheat?
If so, sounds like you have some crud that was dislodged in the flush and is now in the radiator. More thorough flushing sounds like the next step with both hoses off and a garden hose pushing a lot of water both ways through the radiator. .

Yes Sir, prior to all that I didnt have a problem, I am going to try one more bottle of clean and flush after work and pull the lower hose of the radiator and rig a garden hose to the expanstion tank hose and see what happens, other wise I will have to order parts from ford and they will not be here till wed due to the holiday.

The rad is still flowing, just not the volume needed at freeway speed/engine load in order to cool properly.
A radiator shop can check the flow for you.

Well, its starting to come together as to the problem, I noticed the cap was cocked after she overheated and thought I put the cap on cocked, but it is the threads on the tank, they don't hold the cap tight, I put some Teflon tape on the threads and it seems to work, no more parts store parts for me, thanks for the help guys.

It's important to have those caps working right and you can check them an O'reillys at the counter. If those threads are bad I would get another overflow tank.
