With cold weather approaching, experts from Meguiar’s and Prestone offer practical, budget‑friendly DIY tips to prepare your car for winter conditions. These recommendations focus on visibility, windshield care, wheel protection, and cooling system maintenance so your vehicle remains reliable and safe when temperatures drop.

Mike Pennington, Global Director of Training and Consumer Relations at Meguiar’s, and Colin Dilley, VP of Technology at Prestone, share straightforward steps you can take now to reduce winter-related problems and keep your car performing well through the season.

Maximize Visibility

Good visibility is essential for safe winter driving. Inspect your headlights and taillights to ensure they are clean and functioning properly. Cloudy or hazed headlight lenses reduce nighttime and low‑visibility performance; restoring them can make a noticeable difference. Using a headlight restoration kit designed for plastic lenses will improve optical clarity and help other drivers spot you more easily in snow, rain, or fog.

Keep Your Windshield Clear

Preventing ice and frost buildup on the windshield is a simple but crucial step. Use a de‑icer windshield washer fluid formulated to remove light ice and frost and to protect against freezing temperatures. For consistent protection throughout the year, use an all‑season washer fluid to keep your wiper system working efficiently. Proper washer fluid reduces the need to scrape, helps maintain visibility, and lowers the chance of damaging wiper blades or the windshield itself.

Prevent Permanent Wheel Damage

Winter road conditions—salt, grit, and brake dust—can damage wheels if not managed. Clean painted or clear‑coated wheels with an appropriate wheel and tire cleaner to remove corrosive contaminants. After cleaning, apply a protective wax or sealant designed for wheels to help repel dirt and salt and make future cleaning easier. Choosing the right products for your wheel finish and following manufacturer instructions will help prevent permanent damage and keep wheels looking good through the season.

Check Your Cooling System

Cold weather puts extra stress on your cooling system, so inspect antifreeze/coolant for contamination or debris. If the fluid looks discolored or contains particles, flush the system and refill with a proper mixture—typically 50% antifreeze concentrate and 50% distilled water—for optimal freeze and boil‑over protection. If the coolant level is low, top it off with a ready‑to‑use 50/50 premixed antifreeze/coolant. Use a reliable antifreeze tester to confirm the freeze protection level; maintain the recommended 50/50 ratio to protect the engine and the cooling system from freezing and corrosion.

Following these basic, low‑cost steps before the cold hits will improve safety, reduce the likelihood of winter damage, and help your vehicle start and run reliably on cold mornings. Regular checks of lights, windshield washer fluid, wheels, and coolant are quick to perform and can save time and expense later in the season.
