Where is the radiator drain plug on a 1998 Nissan Frontier truck?

The radiator drain plug on a 1998 Nissan Frontier is located at the bottom of the radiator, usually on the passenger side. It is typically a small, plastic or metal valve that can be turned counterclockwise to open and drain coolant. Make sure to perform this operation when the engine is cool to avoid burns. Always have a container ready to catch the draining coolant.
