Over Heating problem

Ok I have changed the thermostat and the water pump and put new fluid in it. I also took my a/c fan and put a toggle on it so I could turn the fan on when I need it. Has anyone ran across the same problem? My next guess will be buy a new radiator I just want to make sure I'm not missing something. Any input would help me out alot.

hows your cap and bottle? I was having the same problem, I changed the cap because mine was bad and I also purged all the air out of the system and I havent had a problem since.

The bottle and cap are as old as the jeep would be my guess. When you say purge the system what exactly do you mean?

It would probably be a good idea to change the bottle and the cap. I knew mine were bad when fluid started to puke out of the cap. By purge the system I meant to bleed the air out of it. I just did it this way.. http://www.naxja.org/forum/showthread.php?t=939188&highlight=drilling+thermostat.. Ever since I havent had 1 problem with my jeep over heating.
