Don’t let this sudden warm weather fool you! It won’t last forever and if you’ve put off prepping your car do it now, because this time of year it can get very cold very quickly. That could mean frozen parts on your car and hundreds to thousands of dollars in damage. If your radiator has been topped off with plain water or antifreeze, a serious cold snap could cause the engine and cooling system to freeze. This would be killing the engine, radiator or other expensive parts.
It is also important to never add pure water or pure antifreeze to your car. Water freezes at thirty-two degrees and plain antifreeze freezes at eleven degrees both above zero. Another system you may not think could freeze is breaks. But, it can happen and lead to a very scary situation. Break fluid attracts and absorbs water, and it is possible for it to get so water logged it freezes, causing very limited braking. Brake fluid should be flushed out and renewed every two years. Also, if you haven’t been using dry gas in your gas tank there could be enough water in it to freeze your fuel lines and stop the car from running. Use isopropyl dry gas once every month year round to prevent water damaged fuel system parts.
