I've changed the antifreeze, the radiator looks fine, I think the thermostat is fine, etc. The car has never overheated but I wonder sometimes what might happen if I'm out in the desert in the middle of nowhere. It would seem that overheating could be related to, or even a precursor to, rod bending.
