How to Care for Your Car in Cold Weather

Cold weather can seriously impact your vehicle’s performance. Freezing temperatures affect your battery, tire pressure, engine oil, and overall reliability. Knowing how to care for your car in cold weather helps prevent breakdowns and keeps you safe on winter roads.

How Does Cold Weather Affect Your Car?

Cold temperatures cause engine oil to thicken, reduce battery power, lower tire pressure, and increase wear on critical components. Road salt also accelerates rust and corrosion.

In short: winter increases strain on your vehicle, which makes preventative maintenance essential.

Winter Car Maintenance Checklist

1. Check Your Car Battery

Your battery can lose up to 50% of its power in freezing temperatures.

• Test the battery before winter
• Clean corrosion from terminals
• Replace batteries older than 3 to 5 years
• Park in a garage when possible

2. Monitor Tire Pressure and Tread

Tire pressure drops about 1 PSI for every 10°F decrease in temperature.

• Check tire pressure weekly
• Inflate to manufacturer recommendations
• Consider winter tires in snowy climates

3. Inspect and Top Off Fluids

• Engine oil (use winter grade if recommended)
• Coolant (50/50 antifreeze mix)
• Winter windshield washer fluid
• Brake fluid
• Transmission fluid

4. Protect Your Car From Road Salt

Salt speeds up corrosion on your vehicle’s underbody and paint.

• Wash your vehicle every 1 to 2 weeks
• Rinse the undercarriage regularly
• Apply protective wax before winter

5. Improve Winter Visibility

• Replace worn windshield wipers
• Use winter washer fluid
• Clear snow from roof, hood, and lights before driving

6. Keep an Emergency Winter Kit

• Ice scraper and snow brush
• Jumper cables
• Blanket and gloves
• Flashlight
• Portable phone charger
• Small shovel
• Sand or cat litter for traction
