November is here, and if you’re in Wisconsin, or neighboring state, you know what that means: winter is coming, and it’s not messing around. Between freezing temperatures, icy roads, and surprise snowstorms, your vehicle is about to face some serious challenges.
The question is: Is your car ready for what’s ahead?
Don’t wait until you’re stranded in a parking lot with a dead battery or sliding on bald tires. Use this checklist to make sure you and your vehicle are prepared for whatever winter throws your way.

Why Winter Vehicle Prep Matters
Cold weather is tough on cars. Batteries lose power, fluids thicken, tires lose pressure, and parts that were “fine” in summer suddenly fail when temperatures drop.
Here’s what’s at stake: - Your safety on icy, snowy roads - Avoiding costly breakdowns and towing fees - Keeping your family warm and secure - Not missing work because your car won’t start
A little prevention now saves a lot of headaches (and money) later. The Winter-Ready Vehicle Checklist
✅ 1. Battery Health
Why it matters: Cold weather can reduce battery power by 30-50%. If your battery is already weak, winter will kill it.
What to check: - Battery age (most last 3-5 years) - Corrosion on terminals - Secure connections - Voltage test (should be 12.4V or higher)
Action step: Get a free battery test at Dedicated Repair. If it’s borderline, replace it now—not when it’s 10°F outside.
✅ 2. Tires
Why it matters: Tires are your only contact with the road. Worn tires on ice = dangerous.
What to check: - Tread depth (use the penny test: insert a penny into tread with Lincoln’s head upside down—if you can see all of his head, replace your tires) - Tire pressure (drops 1 PSI for every 10°F temperature decrease) - Uneven wear patterns - Age of tires (replace after 6 years regardless of tread)
Action step: Check tire pressure weekly in winter. Consider winter tires if you drive in heavy snow regularly.
✅ 3. Antifreeze/Coolant
Why it matters: Coolant prevents your engine from freezing and cracking in sub-zero temps.
What to check: - Coolant level (should be between min/max lines) - Color (should be bright, not rusty or murky) - Freeze point (should protect to at least -30°F)
Action step: Have your coolant tested and flushed if it’s been more than 2 years.
✅ 4. Oil
Why it matters: Oil thickens in cold weather, making it harder for your engine to start and run smoothly.
What to check: - Oil level and condition - Type of oil (consider switching to synthetic for better cold-weather performance) - Last oil change date
Action step: If you’re due for an oil change, do it before winter hits. Ask about synthetic oil for better winter protection.
✅ 5. Windshield Wipers & Washer Fluid
Why it matters: You can’t drive safely if you can’t see. Winter brings salt spray, slush, and grime.
What to check: - Wiper blade condition (replace if streaking or skipping) - Washer fluid level - Type of washer fluid (use winter formula rated to -20°F or lower)
Action step: Replace wipers now if they’re more than 6 months old. Top off with winter-grade washer fluid.
✅ 6. Belts & Hoses
Why it matters: Cold makes rubber brittle. A snapped belt or burst hose can leave you stranded.
What to check: - Cracks, fraying, or glazing on belts - Soft spots, bulges, or leaks in hoses - Tight connections
Action step: Have belts and hoses inspected during your next service. Replace anything questionable.
✅ 7. Brakes
Why it matters: Stopping on ice is already hard. Worn brakes make it dangerous.
What to check: - Brake pad thickness - Brake fluid level and condition - Any grinding, squealing, or vibration when braking
Action step: Get a brake inspection if you’ve noticed any warning signs or haven’t had them checked in over a year.
✅ 8. Lights
Why it matters: Winter means shorter days and reduced visibility. You need all your lights working.
What to check: - Headlights (low and high beam) - Taillights and brake lights - Turn signals - Fog lights (if equipped)
Action step: Walk around your car with someone inside testing each light. Replace any burned-out bulbs.
✅ 9. Heating & Defrost System
Why it matters: A working heater isn’t just comfort—it’s safety. You need defrost to clear windows.
What to check: - Heat output (should get warm within 5-10 minutes) - Defrost effectiveness - Blower motor operation at all speeds - Strange smells when heat is on
Action step: If your heat is weak or defrost isn’t working, get it checked ASAP.
✅ 10. Emergency Kit
Why it matters: Even with perfect prep, emergencies happen. Be ready.
What to include: - Jumper cables or portable jump starter - Ice scraper and snow brush - Small shovel - Bag of sand or kitty litter (for traction) - Blanket - Flashlight with extra batteries - First aid kit - Phone charger - Non-perishable snacks and water - Reflective warning triangles
Action step: Assemble your kit this weekend and keep it in your trunk all winter. The Bottom Line
Winter doesn’t care if your car is ready. But you should.
