I ordered an AUX tranny cooler for my k10...... BUT, I noticed that my stock radiator has more inlets then the new aluminum one has! What gives?...There is a line that goes to the radiator cap, and a line that was above the tranny coolet lines, and they are not on the aluminum one! There is a threaded hole on the new alumin. radiator, but there is no part to attach a hose! HELP!
