To find it, you'll need to:
1. Consult your owner's manual: This is the most reliable source. The manual will have diagrams and specific instructions for your model year.
2. Look at the bottom of the radiator: The drain plug is usually located at the bottom of the radiator, often near one of the lower radiator hoses. It's typically a small bolt or plug. It might be difficult to see without getting under the vehicle.
3. Use caution: The radiator contains coolant which is hot when the engine is warm and can be corrosive. Let the engine cool completely before attempting to drain the radiator. Wear appropriate safety glasses and gloves.
If you can't locate it after consulting your owner's manual and carefully examining the bottom of the radiator, it's best to take your Grand Caravan to a qualified mechanic for assistance.
