Ok, is there a strong difference in temp between the upper and lower hose? Be careful grabbing it, coolant gets fuggin hot! If one is hot and the other significantly colder, you could try removing the tstat to see if it changes. If you don't see any dexcool mud, chances are the water pump isn't circulating coolant. Just be certain you've burped all of the air out of the system before you go chasing these ideas. Also, have you verified proper fan operation when its idling? These are suggestions based on the info at hand.
