What should it cost to fix? on 1992 Dodge Dynasty

What would cause water to pour from the engine? It's close to where the transmission is bolted to the engine. I put water in the radiator, it runs out from somewhere near the back of the car, close to the windshield. I've been told it's freeze plugs. If so about what should it cost to repair?

could be a freeze plug but more likely a hose higher up leaking down
