I hooked up a Magnefine to my cooler lines, but I don't know if it installed correctly. This is for my 06 Ford Ranger. I *think* the fluid flows from the trans, to the top of the radiator, out the bottom of the rad, through an external cooler, and back to the trans. BUT I'M NOT SURE. CAN ANYONE CONFIRM THIS?? Does it go to the external cooler first, then the bottom of the rad, out the top and back to the trans??? And I already tried disconnecting the cooler lines and starting the engine, but fluid just flows out of BOTH lines. Whats the worst that would happen if I installed the Magnefine backwards?
