The radiator drain plug on a 1992 Pontiac Lemans is located at the
bottom of the radiator, typically on the
driver's side. However, it's
not always easy to see. You might need to get under the car to locate it. It's usually a small, typically brass or plastic plug. Look carefully along the bottom of the radiator, feeling for a protruding plug.
Important Note: Before attempting to drain your radiator, consult your owner's manual if possible for the exact location and instructions. Failing to do so correctly could damage the radiator or cause other problems.
