1987 Nissan 200SX 4 cyl Two Wheel Drive Manual 280000 miles
I had to change my starter out on this car and while doing so I had to disconnect the heater hoses to get to he starter bolt. I did not pay very good attention to where the hoses went. They are marked on the hoses as IN and OUT. My problem is I do not know if the top plug is the in or the bottom is the in. Which hose goes where. I hope I explain this well enough for you to help me. I don't know what will happen if I connect the hose the wrong way. At the fire wall the heater core outlets I will call them are on top of each other in a vertical position on on top of the other. Do the hose marked IN goes to the top or the bottom.
