1997 Dodge Caravan Coolant leak

I started my van and what I thought was the universal belt was squieling. I checked the radiator level and added water to top it off. After adding 4 gallons and it still wasn't full, I noticed a large puddle under the engine. Upon looking, could see water running out from somewhere on the passenger side of the engine. I couldn't see from where exactly. It leaked from the same side the belt is mounted on. Where can this be coming from? I have a Haynes manual and haven't checked it yet. It doesn't seem to be holding any coolant in the radiator. I haven't driven it since this happened. Any ideas or advice would be greatly appreciated. My wife and I are on disability and can't afford much. Thanks for any help given.
