Heater valve Broke on highway...

[ExplorerSHO]

I took the old one off and walked to auto part store and got another one.
Problem is the tabs I had on the four hoses. the two heater hoses from the fire wall markers came off. I don't know which hose goes on the top port and which one goes on the bottom port from the firewall to the valve.
PLEASE HELP.

The heater core should be able to flow both directions so inlet and outlet won't likely matter too much... if you just need to get home, remember that you can always temporarily bypass any heater core issues by connecting the coolant supply hose to the coolant return hose. You won't have heat but you won't have a leak either.

Another thing you can try for figuring out the valve paths is blowing through it.
