The radiator drain plug on a 1997 Chrysler Concorde 3.5L is located at the
bottom of the radiator, typically on the
driver's side (left). However, you'll need to get underneath the car to see it clearly. It's usually a small plug, possibly plastic or metal, and may require a wrench or pliers to remove.
Important Note: Before attempting to drain the radiator, ensure the engine is completely cool to prevent serious burns.
