I wouldnt even bother cause of the issues you can have. Simply remove the lower hose and drain it. Also take off the thermostat hose and thermostat. Flush system from the block there. That brass piece in the bleeder on the thermostat neck. So next attach bottom radiator hose. Fill the block with fluid and put in new thermostat and seal. Install the hose and neck. Fill your radiator. Start it up and add as needed. TURN Heat ON! Once its up to operating temperature with cap back on. Also fill your overflow to the line. Bleed out the air afterwords. Total time is 25 minutes. You never said the year but I'm guessing a 2000ish.

SOURCE: where is the drain plug on the radiator buick

The textbook method is to remove the drain plug on the bottom of the radiator.

Most drain plug is make of inexpensive nylon/plastic and it may fall apart while you turn it.

The professional method is to loosen the lower radiator clamp and drop to lower radiator hose.

Drain the coolant onto a large drain pan and recycle the coolant


I just did a FREE write up on air purge from coolant system and how to detect initial state of blown head gasket at the Fixya tip selection.

I have a 2000 buick regal gse it has a 3.8 l engine with a supercharger Im trying to drain the radiator to flush it out and add new antifreeze Im having trouble with the pitcock valve any suggestions

Dont bother with the Pep/Pipcock. Simply remove the hose on the radiator near the water pump. Also pull off the thermostat hose and Thermostat (Buy a new one with seal) Flush it with water till clean. (The block and radiator) Those valves can and DO break. Then you'll need a new radiator. After all is said and done. That brass bolt is the air bleeder on the Thermostat neck.
