Upper to rad, lower to manifold.
On mine the hose from heater core to manifold has two shut of valves, the valve that should be mounted to the inner fender (where you see four clamps) is taken out because it leaked.
The other valve is mounted near the manifold.
I don't know for sure if this is correct.
There is also a clamp holding both hoses to the inner fender.
