I bet all that foam might have been causing air pockets. Just flush, flush, flush.... Stick the water hose in the top radiator, take off the lower hose at the radiator, turn on water full blast- start truck and rev alittle off an on.... Let it rinse for awhile.. If you plan on going ot the track anytime soon, just run straight water, if you just plan on killing everything on the street- add the coolant!!!
