Where is the water pump on a 2000 Dodge Caravan with 2.4 L engine?

On a 2000 Dodge Caravan with a 2.4L engine, the water pump is located at the front of the engine, driven by the serpentine belt. It's generally situated near the timing belt (or timing chain) cover, although you'll have to access it from the front of the vehicle. You'll likely need to remove the serpentine belt to access and replace it. A detailed service manual for your specific vehicle year and engine will give you the most accurate location and access instructions.
