Yeah, I didn't know if just losing a small amount might make the temp drop by dumping the heated fluid. I knew that if it ran too low on fluid it would obviously overheat and the temps would rise, but if it dumped a small amount continuously, might the temperature actually drop? I did see a couple of rubber-like flaps up near the radiator, one on each side. Those must be the "fillers" everyone is talking about. Those are the only "filler" type flaps I saw though, other than the flaps blocking the holes near the front wheels. I didn't see the "X" near the radiator.
