Brutal Cold Takes a Toll on Cars – Are You Making These Mistakes?

If you’ve struggled to start your car during the recent deep freeze, you’re not alone. Subzero temperatures across Minnesota have been testing engines and batteries, leaving some drivers stranded. But experts say a few simple steps can help avoid a cold-weather breakdown.
Turn It All Off First
One of the biggest mistakes? Leaving your heater, defroster, and headlights on when you shut off the engine. In extreme cold, this puts extra strain on your battery when you try to start it. Before turning the key, make sure everything is off—then turn them back on once the engine is running.
Give It a Minute to Warm Up—But Not Too Long
Modern engines don’t need to idle for 10 or 15 minutes like they used to. In fact, letting your car idle too long can cause unnecessary wear and waste fuel. The best approach? Let it run for about a minute before driving, then take it easy for the first few miles while the fluids warm up.
Keep the Tank at Least Half Full
Cold air can cause condensation inside your fuel tank, leading to water freezing in your gas line. Experts recommend keeping at least a half tank of gas to avoid fuel system issues and to ensure you have enough fuel in case of delays.
Check Your Battery and Tires
Cold weather drains battery power fast, especially if it’s more than three years old. Having your battery checked and replaced if needed can save you from an unexpected failure. Also, check your tire pressure—cold air causes it to drop, reducing traction and fuel efficiency.
Scrape the Whole Windshield—Not Just a Peephole
Nobody likes standing in the cold scraping ice, but driving with just a small cleared spot on the windshield is dangerous. It’s best to let the defroster run for a few minutes while you scrape so you have full visibility before hitting the road.
Minnesota Winter Survival Tip: If your car really won’t start in the cold, plugging in an engine block heater overnight can make a huge difference. For those without a garage, investing in a portable battery booster can also be a lifesaver.
With more bitterly cold days ahead, these small adjustments can keep you from getting stranded. Stay warm and stay safe, Minnesota!
