A vehicle that won’t start, won’t warm up, or gets stuck in the snow—these issues are all too familiar in Wisconsin and Illinois during winter. With a tougher season expected, now is the time to prepare your vehicle. Take action early to avoid getting stranded during the upcoming “polar coaster” winter.
What is the Polar Coaster?
The 2020 Farmers’ Almanac predicts a “polar coaster winter” across much of the United States. Blustery and freezing weather will impact northern states east of the Rocky Mountains. January, in particular, will bring heavy snowfall across the region.
Snow, ice, and extreme cold can disrupt your vehicle and daily commute. Therefore, you should prepare your car now for winter conditions in our area.
Get the Right Kind of Car Oil for Winter
During your next oil change, choose the best oil for winter conditions. Cold weather thickens motor oil, which makes it harder for your engine to stay lubricated. To prevent engine strain, switch to a lighter oil.
For example, if you normally use 10W-30 oil, consider switching to 5W-30. This option performs better in colder temperatures.
The right oil helps your engine run smoothly, even in freezing weather. Always check your owner’s manual to confirm the correct oil for your vehicle and climate.
Use the Correct Antifreeze and Water Ratio
Antifreeze is essential for preventing your vehicle’s coolant mixture from freezing. A frozen coolant can expand and cause severe damage to your engine. The ideal antifreeze and water ratio for most climates is a 50-50 mix, which protects your vehicle down to temperatures as low as -35°F. However, since Midwestern winters can be even more extreme, consider increasing your antifreeze and water ratio to 70-30 for added protection against freezing temperatures.
Increasing the antifreeze concentration ensures your vehicle is better prepared for the polar coaster winter and the harsh temperatures that often accompany it. Make sure to inspect your vehicle’s coolant level regularly and top it off with the appropriate mixture.
Ensure That Your Tires Are Ready to Roll
Proper tire maintenance is crucial for winter driving. Cold temperatures can lower your tire pressure, so check your tires frequently to make sure they are properly inflated. For every 10°F drop in temperature, your tire pressure can drop by about one pound per square inch. Your owner’s manual and your tire’s sidewall will tell you the correct pressure for your specific tires.
Additionally, inspect your tire tread. Use the “Lincoln test” to check tread depth—insert a penny into the tire’s tread with Lincoln’s head pointing inward. If you can see all of Lincoln’s head, it’s time to replace your tires before winter begins. For better traction on snow and ice, you may want to invest in winter tires, which are designed for optimal performance in extreme winter conditions.
Make Sure You Can See
Windshield wipers usually only work effectively for up to one year, so inspect your wipers and replace them, if necessary. Next, fill up your windshield washer reservoir with winter-ready windshield washer fluid. When purchasing the windshield washer fluid, inspect the bottle to ensure that it will excel in frigid temperatures. (Be sure to not use plain water, because it will freeze!) Fresh windshield wipers and a full windshield washer fluid reservoir are always great to have when you’re struggling to see the road in a blinding storm. Also, make sure that your vehicle’s windshield defroster is working properly before you find yourself stuck with a frosty or frozen windshield.
Make Sure You Can See
Driving in winter weather can be challenging, so visibility is crucial. Windshield wipers typically last up to one year, so inspect them and replace them if needed. Additionally, fill your windshield washer reservoir with winter-ready fluid. Avoid using plain water, as it will freeze in cold temperatures.
For ultimate visibility, ensure your windshield defroster is working properly. A frozen windshield can quickly reduce your ability to see while driving, making it even more dangerous in snowy or icy conditions.
Do Not Idle Your Vehicle Excessively
While it might seem like a good idea to idle your vehicle to warm it up in winter, this is actually not recommended. According to AAA, idling your vehicle for long periods not only wastes fuel but also increases wear and tear on your engine. Instead of idling for several minutes, start your vehicle and let it idle for just 15 to 30 seconds while you fasten your seatbelt and clear snow and ice from the windshield.
Idling excessively can also put extra strain on your battery, reducing its lifespan. If your battery is old or not holding a charge well, consider having it inspected before the winter season starts.
Final Thoughts: Be Ready for the Polar Coaster
Expect extreme temperature swings and heavy snowfalls this winter, but by following these steps, you can ensure your vehicle is ready for the challenge. Whether it’s using the right car oil for winter or maintaining the proper antifreeze and water ratio, taking care of your car now will help keep you safe and warm on the road.
