Naffi, what is the year of your vehicle? DIY flushing a radiator may not be the fix you're looking for. Consider is the age and mileage of your radiator? You may need the radiator to be "rodded" that will force debris/calcium etc out of the tubes. Also, sounds like your water pump may a suspect, not be working as well as it should. Many factors can exist, plugged water passages in the heads also cause extreme heating.

 

does it over heat only when the air is on? do the condenser fans come on when idling with the air on and when it's warm outside? have you changed the gauge temperature sensor, the two wire one on your thermostat housing?
