ok now im just guessing........

could you have too much water in it????

anyway you could have put the thermostat in up side down?

does the car over heat? if not i would guess to much water.

hope it helps!!

my mother inlaws trep was doing some thing simmilar. as the car warmed up coolant would start to come out the boil over tube on the resavior tank. came out the rad cap on it wasnt keeping enough pressure.
Maybe try that and its a cheap thing to try, under $4.00

Before you start replacing things, does the fan turn on?

Does it overheat at idle only, or highway speed only...or both?

Single or dual fan setup?

man, sounds like your having a tough time.

with the radiator cap off (make sure the engine is cold) and see if the water is circulating through the radiator.

is there any water dripping from the water pump? if not it probly aint the pump.

next i would try to flush the radiator. if that doesnt work flush the engine.

also,i would try running the engine with the thermostat out.

about how long does it take to over heat after you start it?

how it helps and good luck!!
