I used to run an overflow coolant system a while ago and found that the radiator was forever running dry. After months of exploration I could never find the cause apart from replacing the thermostat and converting the radiator cap to a non-recovery system. To this day the radiator is still full. Very weird to me but its fixed.
Good luck.
