It's usually a small valve or fitting, often a plastic or brass fitting, that you can open with a wrench (usually a small one, like a 7/16" or 9/16"). It might be a simple valve you turn, or a screw-type plug you unscrew.
To locate it definitively:
1. Consult your owner's manual: This is the best resource. It will show you a diagram of your vehicle's cooling system and pinpoint the drain location.
2. Look carefully at the bottom of the radiator: Position yourself in front of the vehicle, looking directly at the radiator from the driver's side. The drain is usually at the very bottom, somewhat near the driver's side.
3. Feel around: Carefully feel the bottom of the radiator. The drain petcock will feel different from the surrounding metal.
4. Online resources: Search for "2000 Chrysler Town & Country radiator drain location" along with your engine size (3.3L or 3.8L) on sites like YouTube or repair manuals websites. Visual aids can be very helpful.
Caution: The coolant will be hot if the engine has recently been running. Allow the engine to cool completely before attempting to drain the radiator. Wear appropriate safety gear (gloves) and be prepared for the hot coolant. Also, properly dispose of the used coolant according to your local regulations.
