    What do you mean? One end goes to the fitting on the manifold and one to the water pump.

    Are you asking if it matters witch direction the coolant flows thru the heater coil? Not absolutely sure but I don't think it matter either way.

    According to this... It would appear that the firewall side would go back to the rear of the manifold or the manifold side and the front to the water pump? My heater core is identical to the one in the parts catalog pic below.

    I think water flows out of the pump into the heater core, if I think of it in the am I’ll feel hoses to see. I am old and kinda scattered
