The car overheated on the highway. Coolant in the tank was low, filled it up, but still overheated. Changed thermostat, and checked fan operation. After changing thermostat, added coolant, it seemed to cycle, as had heat in the car, but all the coolant in the tank is gone again, and dont see any leaks/fluid except when it first overheated.
Would I have lost that much fluid when it first overheated. I have added 1-1/2 gallons more of anti-freeze and don't know if I just need to add more, or if there is a different propblem.
