how to winterise a car

[Camargo]

Winterizing your car involves a systematic check of key systems to ensure safe and reliable operation in cold temperatures. The most critical areas are your battery, tires, coolant, and wiper fluid. A well-prepared vehicle starts easily, maintains traction, and has clear visibility, which are all essential for winter driving safety. Start with the 12-volt battery, as cold weather reduces its cranking power. Have it tested at an auto parts store to check its health. If it's more than three years old, consider a replacement. Next, inspect your tires. All-season tires lose effectiveness below 45°F (7°C). For the best safety, switch to winter tires, which use a softer rubber compound that stays pliable in freezing conditions. Check that all tires, including the spare, are inflated to the manufacturer's recommended PSI, as pressure drops about 1 PSI for every 10°F decrease in temperature. Your engine's coolant (antifreeze) is vital. A 50/50 mix of coolant and water typically protects down to -34°F (-37°C). Use a inexpensive coolant tester to verify its freezing point. Also, replace your wiper blades with winter-grade ones and fill the washer fluid reservoir with a solution rated for at least -20°F (-29°C). Standard fluid will freeze and block the system. Finally, prepare an emergency kit with items like a blanket, flashlight, jumper cables, and ice scraper. Here is a quick checklist of key specifications: | Winterization Task | Key Specification / Data Point | Purpose | | :--- | :--- | :--- | | Battery Voltage Test | Healthy reading: ~12.6 volts | Ensures reliable cold-weather starting | | Tire Tread Depth | Minimum safe depth: 4/32" (3.2mm) | Provides necessary traction on snow/ice | | Coolant Freeze Point | Adequate protection: -34°F (-37°C) | Prevents engine damage from freezing | | Washer Fluid Rating | Effective temperature: -20°F to -30°F | Prevents fluid from freezing in reservoir/lines | | Tire Pressure | Inflate to vehicle's recommended PSI | Compensates for pressure drop in cold air |

My method is all about the cheap and easy stuff you can do in your driveway. First, swap out those wiper blades before they get shredded by ice. Then, dump the summer washer fluid and get the stuff that’s rated for like -30°F. Biggest bang for your buck? Check your tire pressure the first really cold morning. They’ll be low, and filling them up makes a huge difference in how the car handles. Keep a small bag with an ice scraper, a blanket, and some jumper cables in the trunk. Takes 20 minutes, saves a lot of hassle.

I focus on the two things that will leave you stranded: the battery and the tires. Cold weather is brutal on an old battery. If it’s struggling to start on a cool fall day, it will fail in winter. Get it tested. For tires, look at the tread. If it’s looking bald, you have no grip on snow. All-season tires are okay, but true snow tires are a game-changer for safety. Don't forget to check the antifreeze strength. It’s a simple test that prevents a very expensive repair.

As someone who commutes early, my priority is visibility and being able to get going quickly. I always use a winter-grade windshield washer fluid; the regular blue stuff freezes solid on your windshield. I also apply a water-repellent treatment to the outside of the glass—it helps rain and sleet bead up and roll off. A little trick is to park your car facing east so the morning sun helps defrost the windshield. A small bottle of de-icer spray in the door pocket is a lifesaver on those icy mornings.

My approach is preventative maintenance. A few weeks before the deep cold sets in, I schedule a quick inspection at my local shop. I ask them to check the battery’s cold cranking amps (CCA), test the antifreeze concentration, and look for any cracks in the serpentine belt that could break under strain. I do this to avoid an emergency. It’s a small, planned cost that provides peace of mind. I also make sure my roadside assistance membership is active, just in case. It’s about managing risk before it becomes a problem.
