Let the car overheat and then check your radiator for cold spots. Make sure the engine is off. If it has cold spots then it needs the radiator. If the fins are gren colored or very loose then it needs a new radiator. Also check to see if you have a bad thermostat. BUT if your car is making a cracking and popping sound in no way loosen or take off the radiator cap as you will get severly burned.
