The radiator drain is on the bottom of the radiator. It is a small petcock valve.
Typically there is a petcock valve on the lower left side of the radiator, unscrew the petcock to drain the radiator. On radiators without a petcock, you would remove the lower hose to drain the system. (Quite messy!)
The oil drain valve on a 2000 Ford Explorer Sport is located near the rear of the oil pan. The radiator drain petcock is located at the bottom the radiator.

Using your owner's manual or your eyeballs, locate your radiator's drain plug. It could be anywhere along the bottom of the radiator, and will be either a screw plug, bolt plug or a petcock (simple drain valve). Be sure you have your used coolant receptacle in place under the drain before you open it up. Look at the bottom of the radiator facing the engine. I there is none then pull off the lower hose.
If it's a 5.4 you have to loosen the petcock on the radiator. There is also a drain valve on each side of the engine that you have to loosen to drain the system. Without this, you'll only get about half of the coolant out with the radiator only.
Search for a drain petcock along the lower edge of the radiator tanks. Loosen the valve with a pliers, but DO NOT OVERTIGHETEN IT. Not all radiators have one. If you can't find one, then you will have to remove the lower radiator hose which will drain most of the coolant from the engine block too.

If there is no drain valve at the radiator you can drain the system at the drain valve on the boiler
