I checked the tech archive and I couldn't find any information on the direction of coolant flow on a Big Block Mopar. I want to know exactly the inlet
(incoming) coolant direction into the water pump and the outgoing direction.there are two holes for coolant on each side of the water pump housing and one side has to be incoming and the other outgoing but I don't know which.
I have a passenger side lower radiator hose connection (73-up style) in case it matters.
