Dodge Caravan leaks coolent

I would look at the intake manifold gaskets and any coolant hoses at the back of the engine. There are numerous items that could be leaking coolant at the back of the engine. I better way to find the leak is to go by Napa or another parts store and get a UV leak detector kit, it comes with dye packs and a 12 volt UV light. They range in price so shop around. You pour the dye into the radiator cap, they reinstall the cap. Start the vehicle and let it idle for about 10 minutes so that the thermostat will open and circulate the coolant so that the dye will mix and they take the UV light and start looking for the bright yellow green liquid that glows from the dye. When you see it glowing that is where it is leaking.
