Most 95 and newer cars (GM) came with low tox anti-freeze that doesn't need changing till 5years or 100.000 miles. If you have passed both those numbers then its a good chance you need some attention paid to your cooling system. New thermostat, hoses, and a flush and fill of new anti-freeze. Your car has an electrically driven fan that goes on with a temperature sensor. This sometimes need replacing because of the severity of heat under the hood of your car. If your engine is running and the cars stands still long enough it can produce temps well past 260 degrees (boil over for anti-freeze) Your radiator fan should run with the A/C or Defrost switched on, that will help cool your engine till you can get it looked at.
Good Luck...

A problem with the radiator cap and the pressure it holds. If the radiator cap does not hold pressure correctly then coolant could boil and therefore the engine would overheat. Another reason might be caused by thermostat failures; it is recommendable that you check it.
The car engine might also overheat due to coolant leaks such as those from the radiator, the hoses, the water pump, the freeze plugs or any others. Also, problems in the water pump could be the cause and therefore you should check it and replace it in case it is needed.
Some other reasons by which the car engine could overheat are problems in the exhaust system which you can discover by checking vacuum readings, pipes and converter. Besides, you should also make sure that the radiator hose has not collapsed and the ignition timing is working properly.
You should also check the electric cooling fan by making sure that the fan motor, the relay and temperature are correct or otherwise it could cause the engine to overheat. Besides this, you should also check the radiator in case there are any debris in it as well as you should check its hose in case it has collapsed.
It is also recommendable that you check the antifreeze concentration which should be 50/50 in order to be correct, otherwise it could cause the car engine to overheat. If you do not find why your engine does overheat, you should ask a mechanic or an expert for advice. You should not try to fix this if you do not have the proper tools and general car knowledge necessary for it.

As mentioned above, I list it the easiest order to check. Electric Fan and Clogged radiator (Spray water from back to clean, replace motor). Water Leak causing Fluid level to drop or lose pressure (Pressure increase the Boiling point) check all the hoses including Heater and check the Radiator especially if it plastic and Cap. Bad water pump which usually leak from a hole (Weep Hole) seals/bearings are going out. Thermostat (Remove and put in a pan of water and bring to a boil to see if it open and close). Maybe a timing problem. Cracked Head or Blown Head gasket.
I may have missed a few, read the above answers, and put them in the order they the easiest to check.

may be the radiator water is low in water or there is leak or may be rusty water need cleaning the water of the radiator check also may be the thermostat is not working

low coolant, bad thermostat, water pump, stopped up radiator or heater core, abuse
