To find it, you'll need to get under the vehicle. Look for a large bolt or plug near the bottom of the engine block, often near the oil pan. It might be a slightly different size than the oil drain plug and will likely be near a hose connection or other coolant related components.
To be absolutely sure:
* Consult your owner's manual: This is the best resource for precise location and details.
* Search online for a diagram: Search on Google Images or YouTube for "2001 Dodge Grand Caravan [3.0L or 3.8L] coolant drain plug" to see photos of the location.
Important Note: Be prepared for hot coolant if the engine has recently been running. Always allow the engine to cool completely before attempting this procedure to prevent burns. Use proper safety precautions, including gloves and eye protection.
