    It's for the bypass hose that recirculates the coolant in the engine while the thermostat is closed. That way there's no hot spots and you get even heating of the coolant inside the engine, until it reaches operating temperature.

    OK, so it does go to the water pump, so where is the other heater hose location, my engine is a project and I got it in pieces so i didn't have the chance to see it together
