Check to see if the cooling fans are running, maybe your thermostat is faulty? Maybe the guage or the sensor is bad, best to have a mechaninc check it out for you.

Both the cooling fans and the coolant keep the engine from overheating. Check your coolant levels and add some if it's low. That should keep the warning light from coming on.

the fans in those cars work with a weird clutch on the fan and they break sometimes so they dont catch the fan and therefore dont create the cooling, you need a special tool to fix it and its better to bring it somewhere then try on your own
