Got to start from the begining on this one...
1. Was it overheating like this before you took it in for the radiator?
2. Dexcool is the wrong coolant to mix with any of the original Ford gold coolant and can contaminate and clog the cooling system if the two were mixed.
3. I'm suspecting your cooling system is either totally clogged up and contaminated, or you have a blown egr cooler or blown headgasket-s or both, especially if it's puking coolant out of the cap.
