How to Prepare Your Car for a Harsh New Jersey Winter

September 26, 2025

As temperatures start to drop and snow appears in the forecast, preparing your car for winter becomes more than just a good idea. New Jersey winters can bring heavy snow, ice-covered roads, and bitter cold that push your vehicle to its limits. A few key steps taken before the worst of winter hits can help ensure your safety, protect your vehicle, and save you from unexpected breakdowns.


Whether you’re commuting to work, driving to school, or just running errands, having a winter-ready car makes all the difference when conditions get rough.


Check and Replace Worn Tires


Your tires are the only part of your car that touches the road, and their condition directly affects your ability to stop, steer, and stay in control. Winter tires or all-weather tires with a deep tread pattern are ideal for snowy and icy conditions.


If your current tires are worn or approaching the tread depth limit, they’ll struggle to grip the road once snow and slush appear. Check for uneven wear and make sure the tread depth is at least 4/32 of an inch. Also, remember that cold air causes tire pressure to drop, so you’ll need to check it more frequently during the winter months. Maintaining proper inflation helps with traction, handling, and fuel efficiency.


Inspect and Test Your Battery


Cold weather puts extra strain on your car’s battery. As temperatures fall, the chemical reactions that produce electrical power slow down, and a weak battery that worked fine in the fall may suddenly fail in the winter.


Have your battery tested before the cold weather settles in. Most auto service centers can perform a quick load test to measure their remaining life. If your battery is older than three years, it may be time for a replacement. Make sure the terminals are clean and securely connected, and look for signs of corrosion around the posts.


Top Off or Replace Vital Fluids


Several vehicle fluids play a critical role in how well your car functions during cold weather. Engine oil, for example, thickens in low temperatures. If you haven’t changed your oil in a while, consider switching to a winter-grade oil that flows better when cold.


Coolant (antifreeze) should also be checked and replaced if it’s old or not mixed properly. A 50/50 mixture of antifreeze and water protects your engine from both freezing and overheating. Don’t forget to fill your windshield washer reservoir with winter-grade fluid that won’t freeze and can help cut through road salt and grime.


Examine the Brakes and Suspension


Icy and wet roads increase the distance it takes to stop. Your braking system needs to be in top condition to keep you safe. Have your brake pads, rotors, and brake lines inspected for wear or damage. If your brake fluid is dirty or low, that should be addressed as well.


Suspension issues, such as worn shocks or struts, can reduce traction and make your ride less stable on slippery surfaces. If your car feels bouncy or drifts on turns, a suspension check before winter weather intensifies is a smart move.


Replace Wiper Blades and Check Defrosters


Visibility is everything in winter driving. Make sure your windshield wipers are up to the task. If they’re leaving streaks or missing spots, it’s time to replace them. Consider installing winter wiper blades that are designed to handle snow and ice buildup.


Your defrosters also need to be working properly to keep the windshield and rear window clear. If airflow feels weak or uneven, your HVAC system or cabin air filter could be the problem.


Keep an Emergency Kit in the Car


Even the most well-maintained vehicle can run into trouble. If you get stuck or stranded during a snowstorm, having a well-stocked emergency kit can make a big difference. Your kit should include:


  • A blanket or warm clothing
  • Ice scraper and snow brush
  • Flashlight and extra batteries
  • Jumper cables
  • Non-perishable snacks and bottled water
  • Small shovel and traction material (like sand or kitty litter)
  • Phone charger and backup battery


This preparation can help keep you safe while you wait for assistance.
