The car was overheating missing fluid. The mechanic said it was the radiator so they replaced that and we drove it home. All was fine drove it 30 miles out to eat and no problems. Then this morning started it and couldn't drive a mile without it overheating again and the same original problem. Radiator fluid is leaking out underneath the car by the rear of the driver's side door. What could this be?

If you have rear heat, may be related to those heater lines. On mine, it was the water pump gasket. Coolant puddled about center of drivers door. Changed water pump and gasket and about 2 weeks later leak appeared again. Put in a steel gasket from NAPA and problem solved. Two years now. Found leak by pressuring system with Harbor Freight kit.
