[quote I just want to drain the radiator and add new anti-freeze from my Chrysler Dealer. ][/quote]

Why do you want to drain only the radiator and not the engine block and heater core? Are you trying to save money?

It is virtually impossible to drain just the radiator. If you remove the drain plug at the bottom of the radiator, radiator contents will drain. However some of the coolant in the engine block and all in the water pump and lower hose will drain through the lower radiator hose, into the radiator and out the drain plug.
