If my thinking is correct the top hose comes off the intake manifold behind the thermostat. That's where the hot water should come from.
It enters the top of the heater core and cools like a radiator and leaves through the bottom hose to the water pump which should be sucking the coolant from the heater core.
In fact I'm going to hook it up that way.. just need a non leaking heater core.
