Is the thermostat opening at the proper temp.? Does it overheat while driving at speeds over 35MPH? Was Proper coolant mix put in and air purged out of the system (warmed-up with heat on high -temp.-not fan speed)? Is radiator cooling fan cycling on when reaches operating temp.?

with the car running, check for random air bubbles in the coolant overflow tank, if theres any, chances are it's your head gasket.
