Preparing your car for winter involves more than just swapping out summer tires—it’s also about ensuring your fluids and filters are ready to handle colder temperatures. Here’s what you need to check to keep your car running smoothly when the weather turns icy.
Engine Oil
Cold weather can thicken engine oil, making it harder for the engine to start and function efficiently. Check your oil level using the dipstick, ensuring it’s at the proper level. Consider switching to a winter-grade oil if your vehicle’s manufacturer recommends it for colder climates.
Coolant
Coolant, or antifreeze, prevents your engine from freezing in subzero temperatures. Use a hydrometer to check the coolant’s freeze point and ensure it’s at the proper 50/50 mix of antifreeze and water. Top off the reservoir if needed and look for signs of leaks, as even a small leak can cause big problems in freezing conditions.
Transmission Fluid
Transmission fluid ensures smooth gear shifts and overall performance, even in cold weather. Check the fluid level with the dipstick (if your vehicle has one) and ensure it’s clean and red or pink in color. Dirty or low transmission fluid can thicken in the cold, causing shifting issues.
Windshield Washer Fluid
Winter roads can mean dirty windshields, so make sure your washer fluid reservoir is full with a winter-grade formula that won’t freeze. Standard fluids can freeze in extreme cold, leaving you unable to clean off snow, ice, or salt spray.
Air and Cabin Filters
Clean filters help maintain proper airflow to your engine and cabin. Check the air filter for dirt or debris and replace it if it looks clogged. A clean air filter can improve fuel efficiency and performance, especially in colder weather. Similarly, ensure your cabin filter is clean to keep your heating and defrosting systems running efficiently.
Trust Professionals for a Thorough Inspection
While you can check some of these items yourself, a professional inspection ensures every component is ready for winter. They can identify potential issues and help you avoid breakdowns when temperatures drop. By giving your car’s fluids and filters the attention they need, you’ll be ready to take on winter with confidence, no matter how cold it gets.
