Things to do to prep your vehicle for winter weather.

When you live in Minnesota, winter doesn't just happen-it hits. One day you're enjoying a cool fall breeze, and the next you're scraping ice off your windshield in the dark at 6 a.m. Preparing your vehicle before the first snowfall is one of the smartest ways to prevent breakdowns, accidents, and expensive repairs later in the season.
Here's your ultimate Minnesota winter car checklist-15 must-do tasks to get you road-ready before temperatures drop and the snowbanks pile up.
1. Check Your Tire Pressure Weekly
You lose about 1 PSI for every 10°F drop in temperature. Low pressure = poor traction + reduced fuel economy.
2. Test Your Battery
Minnesota cold kills weak batteries fast.
✔ Replace if it's 3+ years old, slow to crank, or tests below recommended voltage.
3. Top Off or Replace Antifreeze
Ensure your coolant ratio is correct (often 50/50).
✔ This prevents engine freeze-ups and costly cracks.
4. Switch to Winter-Grade Washer Fluid
Regular fluid freezes around 32°F.
Winter formula stays liquid down to −20°F or lower-a must in Minnesota.
5. Inspect Wiper Blades or Upgrade to Winter Wipers
Ice + slush + freezing rain = destroyed visibility.
Winter blades have rubber housings that prevent ice buildup.
6. Check Your Brakes
Slick roads require responsive brakes.
If you hear grinding, squealing, pulsing, or feel pulling, get them inspected.
7. Inspect the Heating and Defrosting Systems
Be sure to test the heating and defrosting systems and inspect their filters to ensure safe, reliable performance in cold-weather conditions.
8. Protect Your Car From Salt Damage
Salt causes rust-especially on Minnesota roads.
✔ Consider: undercoating, ceramic coating, or regular undercarriage washes.
9. Check 4WD/AWD Systems
Don't wait for a blizzard to find out your 4-wheel drive isn't engaging properly.
10. Pack a Winter Emergency Kit
Include:
Blanket
Heavy gloves & hat
Ice scraper & snow brush
Jumper cables
Flashlight
First aid kit
Snacks & water
Portable phone charger
Sand or kitty litter for traction
Small shovel
This is vital for rural or highway travel.
11. Keep Your Gas Tank at Least Half Full
Prevents fuel line freezing and keeps you safe if you get stuck in traffic or stranded.
12. Check Your Lights (All of Them)
Short winter days = more night driving.
Clean lenses and replace dim, foggy, or burnt-out bulbs.
13. Consider Installing a Remote Starter or Block Heater
In extreme temps (−10°F and colder), block heaters make cold starts easier and reduce engine wear. Remote starters add comfort and safety by warming the vehicle before driving.
14. Checking Your Oil
Making sure your oil is changed on schedule during the winter is crucial because cold temperatures thicken old oil, reduce lubrication, and can lead to unnecessary engine strain and costly repairs.
13. Make Sure You Have a Spare
With ice and road debris being tougher to avoid during winter driving, it's essential to protect your vehicle from extra wear and tear and always keep a spare donut tire and jack in your car for unexpected emergencies.
