Winter Car Care Checklist: Keeping Your Car in Top Shape During Cold Months

February 26, 2025 | 5 Minute Read

As winter settles in, Canadian drivers know that harsh weather can put their vehicles to the test. To avoid unexpected breakdowns, maximize your car’s performance, and ensure a safe winter driving experience, it’s essential to winterize your vehicle. Here’s a comprehensive winter car care checklist, from checking antifreeze levels to protecting your battery from freezing temperatures.

Check Your Antifreeze Levels

One of the first steps in winter car preparation is ensuring your antifreeze levels are up to par. Antifreeze, or coolant, keeps your engine from freezing in cold temperatures. A 50/50 mix of antifreeze and water is typically recommended, but it’s wise to check your car’s owner’s manual for the best ratio. Inspect the fluid level and top it off if needed, especially before those freezing temperatures set in.

Invest in Winter Tires

Winter tires are a must for Canadian roads. Unlike all-season tires, winter tires have specialized rubber compounds and tread patterns designed to maintain flexibility and grip in cold, icy, and snowy conditions. When temperatures drop below 7°C (45°F), all-season tires start to harden and lose traction, making winter tires the safer option. Be sure to check your tire pressure regularly, as it can decrease with colder temperatures.

Inspect and Maintain Your Battery

Cold weather is tough on car batteries, reducing their capacity and making it harder for them to start your car. Before winter fully kicks in, have your battery tested to ensure it’s strong enough to withstand the season. Clean any corrosion on the battery terminals, and if your battery is more than three years old, consider replacing it to avoid getting stranded.

Fill Up on Winter Washer Fluid

Visibility is crucial for safe winter driving. Regular washer fluid can freeze in sub-zero temperatures, so make sure you’re using a winter-specific windshield washer fluid that won’t freeze on contact. Additionally, check that your windshield wipers are in good shape—if they’re streaking or skipping, replace them with heavy-duty wipers designed for winter.

Inspect Your Brakes

Snow and ice demand optimal braking power, making winter the most important time to inspect your brakes. Check the brake pads and rotors for any signs of wear and tear, and listen for squealing or grinding noises. If anything seems off, it’s best to get your brakes serviced to ensure safe and reliable stopping power.

Prepare an Emergency Kit

Winter weather can be unpredictable, so preparing an emergency kit for your car is a smart move. Include essentials such as a flashlight, blanket, non-perishable snacks, a first-aid kit, and extra windshield washer fluid. Adding jumper cables, a small shovel, and even a bag of sand or kitty litter for traction can be lifesavers in icy conditions.

Check Your Engine Oil

Cold temperatures can cause your engine oil to thicken, making it harder for your engine to run smoothly. To help your car start easier in winter, consider switching to a winter-grade or synthetic oil that remains fluid in colder weather. Check your car’s manual for recommendations or consult your mechanic about the best oil type for your specific vehicle.

Inspect the Heating and Defrosting System

A working heating system is essential for comfort, and an effective defrosting system ensures clear visibility. Test your heating and defrosting functions to make sure they’re operating correctly before winter driving conditions get tough. If you notice any issues, have a professional look at it as soon as possible.

Protect Your Car’s Exterior

Winter road salt, ice, and snow can be harsh on your car’s paint and undercarriage. Wash your car regularly to remove salt buildup, which can cause rust, and consider applying a protective wax coating. For added protection, especially for the undercarriage, consider a rust-proofing treatment to shield it from winter’s harsh conditions.

Keep Your Gas Tank Full

Keeping your gas tank at least half full during winter helps prevent moisture from building up in the fuel line, which can freeze and cause issues. A full tank also ensures you’ll have enough fuel to keep the heater running if you ever get stuck in a winter storm.
