Im doing my heater core tomorrow(already have the car apart) but i was looking at the new one and in one of the tubes have a "inlet" tag, so what hose should go there? the one on the passanger side or the drivers??... does it really matter?
I think it's just a core material with 2 nipples so it shouldn't matter. My TurboCoupe core came with a loose plastic valve that was supposed to be installed on the inlet side. I think it was to reduce the gurgling noise.
