99 Dodge Grand Caravan

I own a 99 dodge grand caravan it is over heating. I have found an leak in the motor but cannot tell where it is coming from what I am seeing is coolant that looks like it is coming from the crank shaft but when jack up the van it runs out the other side of the motor. Was wondering where the water pump is at if the coolant could be coming from there and could run from one side of the motor to the other or if it would be more likely an hose some where have tried to see where the water is coming from and how it is running from one side of the motor to the other but cannot find it please help this is the only means of transportation that my family has and is the one that I travel to and from work in everyday must fix it sincerely Jarrod Brown.
