If it only heats up while its not driving eg in idle it might also be your auxiliary fan or fan clutch. When the car moves, outside air cools radiator so temps dont go up. but it doesnt sound like thats your problem. Any lights on? also wats ur coolant level? no leaks correct? best way to check for leaks is to put cooling system under pressure test, which i would recommend doing. when under pressure, u can check for leaks near w/p. might also have crack in radiator that is very small. otherwise it is probably your thermostat. hope i could help, but definately get the system pressure leak checked...
