Have you had the cooling system flushed? The radiator may be plugged.

Those cars don't trap air they self purge as long as the coolant level is full there isn't any air. If the coolant temp sensor is working correctly what is the actual temp the radiator fan coming on at?The temp gauge can't be trusted because there is only one temp sensor for the gauge and the computer. Does the radiator fan come on with the ac on if the ac works?When the radaitor fan is on is there a lo of air being pulled thru the radiator? When does it overheat?Stop and go traffic around town freeway?Does your car still have its air dam?If that's missing it will overheat under certain driving conditions. Did you check the coolant temp sensor connector for being corroded its common on those cars.

Could be clogged radiator remove radiator and flush with garden hose several times. See if any junk comes out if it does you may even need to get a new radiator. If that's not the problem my assumptions would be a blown head gasket
