Where is the radiator drain plug for a Chevy Impala 3.4?

The radiator drain plug on a 1998-2005 Chevy Impala with the 3.4L engine is located at the bottom of the radiator, on the driver's side. It's usually a small, plastic or metal plug. You might need a wrench or pliers to remove it, depending on the type of plug. Be prepared for hot coolant if the engine has been running recently! Always let the engine cool completely before attempting this.
