Heat and Cold


When adding antifreeze to a car, should you gauge the amount based on expected low temperatures or expected low wind chills?

After referring to your car’s owner’s manual, add the appropriate amount of antifreeze to protect your radiator at the lowest expected air temperatures for your region. You can research the Internet—sites such as are helpful—to find what the expected low is for your area. This generally works for urban areas, but if you live in a rural area you might wish to subtract an additional 20°F (9.5°C) to be safe.
