The thermostat housing connects to the lower cooling pipe. There is a gasket under the water outlet that the upper hose connects to at the engine. It is a 4 dollar part so it may be worth looking into.

I would do a pressure test and see if you can tell where it's squirting out from. Maybe the hose fitting on the top of the engine where the top hose connects. There are 3 bolts that hold the fitting on if I remember right which if loose/corroded can cause a leak.
