Where is the radiator drain on a 3.4 V62002 Chevy Impala?

Bottom left (driver side) of radiator on the side facing the engine. It is a plastic petcock, and only needs to be turned 1/4 CCW.

Thanks For The Info I've Been All Over Seem To Keep Missing It.So Thanks Again.

Not all radiators have a drain. If there is not drain, loosen up the lower radiator hose.

it takes a 3/4 inch socket short or long to loosen it up,. what i did was there is a lower part of the frame that holes the bottom part of the radiator in place. there is a piece of the metal frame that i cut out about 3/4 inch by 2 inch long to gain access to the drain plug for the socket. It well not cause any damage to the integrity of the frame mount. works great real easy,
