Water pump?

Had fits finding the leak in my 2003 4.0. Mine was coming from the plastic housing the upper radiator hose connects to. It's right in front by the intake manifold. The only thing keeping it from leaking is a very thin o ring on the botton of the housing. It could also be cracked. Get a pressure tester from your local auto parts store. Once you pump it up the pressure, you'll see the leak.

Hopefully it is not the waterpump on the v6. They are not easy to change. Taking the fan off first is the hard part, then twelve or thirteen bolts.
