Your car is put through some of the most punishing conditions of the year when it gets cold. Freezing mornings, narrow tires, road salt and heavy snow can quickly make a dependable car into a breakdown waiting to strike. Only when their battery is dead in the cold, their tires have lost all traction or they can’t start the engine do many drivers admit that they didn’t maintain their vehicle properly for winter.
An adequate cold weather car maintenance checklist can keep those problems from ever occurring. Winter not only affects comfort but safety, fuel efficiency and also expensive components such as batteries, tires, brakes and cooling systems. Skipping winter prep can result in expensive repairs, unsafe driving conditions or getting stuck on the side of the road in subzero temperatures.
The good news is that caring for your car during winter doesn’t have to be complicated or costly. By following an easy checklist and arming yourself with the necessary tools, you can ensure that your vehicle is running smoothly throughout the season. In this in-depth guide you’ll discover what to check, how to do it step-by-step, and what products are worth your hard-earned cash—so your car stays up and running in even the most brutal weather.
