    Heater Core Inlet/ Outlet

    I have devised a plan to keep my heater core from exploding.

    Would anyone know which line is the inlet, and which is the outlet? They are two different diameters... I am inclined to believe the large is the inlet, but I may be wrong.

    Anyway you can explain it would be fine. Does the coolant enter via the intake, or the water pump?

    Does it matter?

    coolant enters from the intake, returns to the water pump. I dont remember which pipe is smaller, but the one closer towards the engine is usually the inlet, and the side towards the fender is return. Not sure it really matters, but the hoses usually route nicer when hooked up that way.

        Funny, the in/out on the cores I've seen all look the same size. But, I've never measured them either.


        Are you going to do the H-fitting routine or something else entirely?

          Its a secret, Michael. I'll divulge when I have made sure that it works.

              i always wanted to come up with some sort of plumbing involving GM style vacuum operated valves to bypass the core under heavy engine loads. Wouldn't be too hard to do really, just plumb it to manifold vacuum and spring it so that with no vacuum, the valve opens and with vacuum it shuts the bypass.

                I like this idea.
