Georgia winters are mild compared to the north, but the temperature swings and occasional freezing nights can still affect your vehicle. Here’s how to keep your car running smoothly through the cooler months.
Battery Health
Cold temperatures reduce battery capacity. A battery that’s marginal in summer may fail on the first cold morning.
- Have your battery tested before winter
- Clean any corrosion from terminals
- Make sure cables are tight and secure
- Consider replacement if battery is 4+ years old
Check Your Antifreeze
Your coolant needs to protect against freezing. Even in Georgia, we can get into the 20s, and coolant should protect well below that.
Pro Tip: Antifreeze should be changed every 2-3 years regardless of mileage. Old coolant loses its protective properties.
Tire Pressure Matters
Tire pressure drops about 1 PSI for every 10°F temperature drop. That low tire pressure warning in the morning? It’s probably just the cold. But check and adjust anyway – properly inflated tires are safer and more fuel efficient.
Wiper Blades and Washer Fluid
Georgia’s winter rain and morning fog demand good visibility:
- Replace streaky or worn wiper blades
- Use winter washer fluid that won’t freeze
- Keep the reservoir full
Heater and Defroster Check
Don’t wait for the first cold snap to discover your heater isn’t working. Low coolant or a failing thermostat can prevent proper heating.
Oil Considerations
Modern synthetic oils handle temperature variations well, but if you’re running conventional oil, make sure the viscosity is appropriate for cooler weather.
