If the coolant is more than 5 years old, it would be recommended to drain, flush and refill the coolant system with a fresh antifreeze mixture of 50% antifreeze and 50% water. This should protect the system down to -34 degrees F. A close inspection of hoses, radiator and possible replacement of the thermostat would also be recommended.

There are two major signs that the car radiator is broken. One sign is that the radiator will not hold fluid. Another sign is that there is smoke coming from under the hood of the car.

Yes. Never add pure antifreeze. Pure antifreeze will actually freeze before a 50/50 mix. Add coolant that is a 50/50 mix of antifreeze and distilled water. You can buy it already pre-mixed.
