On mine the bottom one on the rad is the inlet to the rad, but make sure by disconnecting one of the lines at the rad and put a pop bottle over the line and a cup in front of the rad hole and have someone fire the car up for just a second. It is important to get the flow right and this is a sure way to tell.
