How to Winterize a Car: Steps to Prepare for Cold Weather Driving

The elements pose a unique challenge to motor vehicles, and that is particularly notable when seasons change. Though the shift from spring to summer or even summer to fall may not be too significant, drivers who want to safeguard their vehicles would be wise to take certain measures to prepare for winter weather.

Winterizing a car can be an important part of vehicle maintenance, especially for drivers who live in regions where winter is marked by cold temperatures and significant snowfall. As fall gives way to winter, drivers can take several steps to prepare their vehicles.

One of the first steps is to address tires and tire pressure. The experts at Kelley Blue Book note the danger of aging or poorly inflated tires, particularly in winter. Icy, wet and snow-covered roads can be dangerous to traverse, so it benefits drivers to examine their tires before winter. Worn treads reduce traction and make it more difficult for vehicles to stop, which is already challenging on icy roads. It is equally important to keep tires properly inflated, as KBB reports each 10-degree dip in temperature can lead to a one-pound loss in air pressure. Poorly inflated tires can decrease both performance and safety.

Another step is to check the battery and replace it if necessary. The automotive experts at Firestone note that sinking temperatures slow the chemical reaction within vehicle batteries, reducing the amount of power they can generate. Firestone estimates a battery can lose as much as 60% of its strength in freezing temperatures. The company urges drivers to get a battery assessment before winter to ensure it is strong enough to endure the coming months. If the assessment indicates weakness, the battery should be replaced before winter arrives.

Drivers also should check fluid levels. Routine vehicle maintenance at an auto shop or dealership typically includes topping off fluids. This ensures the vehicle has coolant, which KBB notes is formulated to resist freezing. Without sufficient coolant, an engine can suffer significant damage. Windshield washer fluid also should be filled to ensure the windshield can be cleared of salt during and after snowstorms. A pre-winter oil change can help the vehicle run smoothly throughout the colder months.

Finally, drivers should inspect belts and hoses. KBB notes cold weather weakens these parts, which can become brittle and fail in low temperatures. Belts and hoses should be checked before winter, as engines can overheat, electrical system problems can develop and power steering may be compromised if they are neglected.

Winter can be a challenging season for cars and trucks. Taking steps to winterize a vehicle before temperatures drop can make it safer to be on the road when the weather turns cold.
