    Well,I put the new water pump,t-stat and fan clutch in the sohc 4.0 today and shockingly it is still overheating under a load and at slow travel.Im ok with putting everything on that I did because it was all the original factory parts and they have 200,000 miles on them but,I guess my next step will be a new radiator.

    Have you checked the radiator cap? A bad cap will cause overheating as well.

    I tried the radiator cap today and it still overheated when under a load.The only 2 options left are radiator and head gasket.I have no water in oil and no steam from tailpipe so Im not thinking its the head.

    Usually a head or gasket problem. Be sure ALL air has been purged from the system.

    Sounds like a HEAD-ACHE.... Haha.. sorry. Seriously, id bet it has something to do with your heads, gasket or crack. I did some of the remedies you tried. I just finished replacing the heads and gaskets, one head had a crack. Solved my problem.
