Where is the radiator drain plug on a 2000 F150 XLT extended cab 4.2 liter V6?

The radiator drain plug on a 2000 Ford F-150 XLT with a 4.2L V6 is located at the bottom of the radiator, usually on the driver's side. It's a small bolt or plug, often requiring a wrench or socket (usually around 1/2" to 9/16"). It's best to look closely at the bottom of the radiator itself – it will be a slightly recessed plug or bolt, often with a slight lip or protrusion to make it easier to grip with a wrench. Be careful as coolant will be hot if the engine has been running recently.
