How do you flush the radiator of a 2000 commodore Where's the drain plug?

I also have a 2000 commodore. It is very simple. Follow these steps. # First, disconnect the battery of your car. # Take off the radiator cap (the cap on top of your radiator) # Take a small hose (approx. 3ft) # Put the hose in the radiator as far as you can # Suck on the hose until you start to see/taste the antifreeze rise (if you consume any antifreeze contact your local poison control immediately) # There is no drain plug
