Is it REALLY overheating or is the useless gauge just saying that? Need to hook up a cheap scanner and see what the real temperature is. Could be a cheap temperature sensor that needs to be replaced. Starting in 06' that darn sensor changed locations, to the passenger side, way in the back. 02-05, sensor was cake to do, right above the thermostat. If scanner is reading higher than the rating on your thermostat, you could have a headgasket problem. Have your coolant checked by a pro for any oil in the coolant.
Forgot to mention, you could just have air in the system too. Which is fixable too.
