- Antifreeze: Make sure the level is right and the ratio with water is 50/50.
- Wiper blades: They’re generally in prime shape for only a year or so. If they’re smudging or separating now, they may not be up to the task when you really need them.
- Windshield washer fluid: top it off.
- Ice scraper: Make sure it’s in the vehicle.
- Heater and defroster: Make sure they work, not just make noise.
- Tires: Check your tread depth and air pressure. Check the air in your spare too.
- Battery: Most batteries have their estimated life noted on the top. If you don’t have plenty of juice to make it through the winter, replace your battery early.
- Flares: If you’re stuck near traffic, position flares near your car to be more visible to approaching vehicles.
- Carry a Winter Emergency Kit. The basics: blanket, gloves, boots, flashlight, sand or kitty litter (for traction if you get stuck), jumper cables, extra windshield washer fluid, water and a couple energy bars. A shovel too, if you have room.
If you don’t have the time, talent or tools to check these important points, your mechanic does.
