The radiator drain plug on a 1998 Chevy pickup is typically located at the
bottom of the radiator, on the
driver's side. However, the exact location can vary slightly depending on the specific engine and trim level. It's usually a small, threaded plug, often brass or plastic. You might need a wrench (typically a small socket or open-end wrench) to remove it.
Before attempting to remove it, be sure the engine is completely cool to avoid burns from hot coolant. Also, have a drain pan ready to catch the coolant.
