heater core question

Hey guys I just finished the replacement of my injector cups and I replaced every hose on that engine and when i replaced the heater hoses I believe I hooked them up right but just want to make sure. Is there an IN and and OUT on the heater core or does it not matter???? Im only asking simply because my legs feel like their on fire. Im wondering if the hot coolant is flowing through with out demanding it. I havent drove the truck in a while so Im questioning everything.

Thank you,
AJ

The heater core is not directional. I am the same way, you work on something and every little noise drives you crazy.

Its non-directional but if your like me and have to have it perfect, IN on the left side and OUT on the right side.

The line that goes out goes to the waterpump on the vertical inlet by the front cover.
