Where is the radiator drain plug on a 1999 Subaru Impreza?

On a 1999 Subaru Impreza, the radiator drain plug is typically located at the bottom of the radiator, on the driver's side. It's a plastic or metal screw-type plug that can be turned counterclockwise to open. Make sure to have a container underneath to catch the coolant when draining. Always allow the engine to cool down before attempting to drain the radiator to avoid burns.
