Seems to me that you could have an air lock, try loosening the rad cap slightly and run car until fans kicks in, squeeze upper rad hose a few times to push any air out. Careful with hot hoses. see if this helps.

91 Mustang GT running Hot


does the fan come on when supposed to? you could hook your fans to a toggle switch and run them manually from start to finish this may help. also did you bleed the system after replacing these parts and purge all air from cooling system? is the coolant coming out of the resovoir hose?

1990 Ford Mustang GT Still Running Hot!


check to see if you can spin the fanwhile the engine is cool it should spin freely,if it doesnt fan clutch,also I would switch the fan back to oringinal just to test if this is the problem,if it is youll have to design a different fan shroud if you want to use you new fan,if everything done above is ok with the engine cool take off the radiator cap and squeeze the bottom hose 4-5 times in burst this will make sure you dont have air in the system,if this is helpfull please vote me a fix ya
