What is the most important pre-winter maintenance item for Indiana drivers?

Battery testing is the single most important pre-winter check. Cold weather dramatically reduces battery capacity, and a battery that starts reliably in summer can fail completely on the first cold morning of winter. Have it load-tested if it is more than 3 years old.

Should I use winter tires in Indiana?

Dedicated winter tires provide significantly better performance than all-season tires in severe winter conditions. For Indiana drivers who regularly travel in snow and ice, winter tires mounted on a separate wheel set are worth the investment. For moderate winter use, quality all-season tires are acceptable.

Do I need different windshield washer fluid in winter?

Yes. Summer washer fluid freezes in cold temperatures and can damage the washer fluid reservoir and lines. Switch to winter-rated washer fluid rated to at least -20°F before temperatures drop. This is an inexpensive maintenance step with significant consequences if ignored.

How to Prepare Your Vehicle for Indiana Winter

Indiana winters range from mild to severe, and a vehicle that ran perfectly through summer can fail or perform dangerously when temperatures drop and road conditions deteriorate. A pre-winter maintenance check is not a luxury, it is a practical investment that prevents breakdowns, extends vehicle life, and keeps you safe when Indiana roads are at their most challenging.

Battery

Cold weather reduces battery capacity significantly. A battery at 32°F has roughly 65 percent of its room-temperature capacity, and at 0°F this drops to about 40 percent. At the same time, cold engines require more energy to start. This combination means a battery that starts your vehicle reliably in September may not start it in January. Any battery more than three years old should be load-tested before winter. A battery that tests weak should be replaced proactively. A battery replacement costs $100 to $200 and takes 30 minutes. An emergency battery jump in a parking lot in January is far more expensive in time and frustration.

Tires and Tire Pressure

Tire pressure drops approximately one PSI for every 10-degree Fahrenheit drop in ambient temperature. A tire properly inflated at 35 PSI in 70-degree September weather will read approximately 30 PSI when temperatures drop to 20 degrees in January. Check tire pressure when temperatures drop significantly and add air as needed. Also check tread depth before winter, since tires that are marginal in summer provide inadequate grip on snow and ice.

Fluids

Check coolant concentration with an inexpensive tester to verify it is rated for temperatures below -20°F. Replace windshield washer fluid with winter-rated formula. Check power steering fluid and brake fluid levels. If you have a rear-wheel-drive or four-wheel-drive vehicle, verify differential and transfer case fluid are in good condition before heavy winter use.

Emergency Kit

Keep an emergency kit in your vehicle throughout winter: jumper cables or a portable jump starter, an ice scraper and snow brush, a small shovel, kitty litter or traction sand, a blanket, a flashlight, and basic hand tools. Indiana winter breakdowns are uncomfortable; being stranded without these items makes them dangerous.
