It may or may not have a drain plug for the radiator. Look at the bottom of the radiator usually on the passenger side of the car. It doesn't really look like an actual plug. It is more like a plastick wing nut, just unscrew it and it should drain. Some radiators don't have drain plugs at all. If it doesn't just take off the lower radiator hose from either the radiator or the engine block and do it that way i think the sunfire drain is on the driverside of radiator facing forward. it should be a 1/4 inch hole in center. you have to turn and pull to drain. be careful not to damage plug or radiator.
