    Im working on getting the heater core flushed, not the most mechanically inclined individual.
    Ive got no heat in the cab. If i keep the air off for a while and turn it on i get some warmth for a second and it disappears.

    Ive watched a lot of videos on how its done and its pretty strait forward in them however i can’t tell which is inlet and which is outlet.
    The coolant tubes that run to them are T In both spots. Pretty sure i cant figure out which one is inlet and which is outlet just by letting it heat up because its always running past the core (doesnt have a vaccum ran valve to control when it goes in , at least as far as i can tell).

    If i remove them im going to guess im gonna have a mess of coolant coming out.

    Any guidance here?

    Core flow direction isn’t really important considering you should flush the core both directions.
    If there is a concern about which hose goes where just mark one hose and the port it attaches to.
