go to the auto parts store and ask them for a liquid i can't remember the name of it but it will go in your anti freeze and make it run cooler
just tell them its to stop over heating
clutch fan flushed the system? the car over heats only in traffic if you on the interstate its fine but stop and go traffic it starts going up not right away but after like maybe 10 min or so its almost all the way up once it gets to the mark before the hot mark its bubbling in the over flow...
