radiator

where is the radiator drain plug on a 1994 Buick Century, thanks PJ81

Bottom edge of the Radiator, DS (Drivers Side) of the car, The drain plug will be plastic and facing towards the engine. It will look like the Black drain plug in this pic. With the engine COLD, Just unscrew the drain plug and have a container to catch the coolant in to dispose of it properly....You dont have to pull the drian plug all the way out of the hole, just unscrew it.
