Okay. Pretty much, does that involve leaving the */C off, filling up the system with coolant, and cranking it over and seeing which hole the pump pushes coolant out of? Sorry if you already explained, but want to be sure of what I'm doing.

Note: I blew air into those ports with the yellow O rings...in one, coolant blew out and air come out of the lower radiator hose (which I pulled off to drain the coolant) and another emitted air from what seemed to be the top of the radiator, I'm assuming the upper hose. Does this help? It sounds right.

You got it.

Sweet
