Winter’s on the way, and while it’s relatively mild across most of New Zealand, it still throws a few curveballs. From icy windscreens to soggy roads, your car cops it just as much as you do. Here are a few easy tips to get your car ready for winter so you can keep safe and stress-free.
1. Inspect Your Tyres
Wet and slippery roads are common during winter, so it’s crucial to check your tyre pressure and tread depth. Worn or underinflated tyres reduce grip, increasing your stopping distance.
Pro Tip: Use a tread depth gauge. If your tyres are below 3mm, consider replacing them. If you’re in a hilly or rural area, all-weather tyres may provide better performance during the colder months.
2. Check Your Battery
Cold weather can put extra strain on your car’s battery. A weak battery might struggle to start the engine, especially on chilly mornings.
Pro Tip: Have your battery tested before winter sets in. Many garages offer free battery checks. If it’s over three years old or showing signs of fatigue, it could be time to replace it. Keeping a set of jump leads in your boot is also a smart precaution.
3. Replace Wiper Blades and Top Up Washer Fluid
Winter often means more rain and mist, making clear visibility essential. Worn wiper blades or low washer fluid can seriously reduce your view of the road.
Pro Tip: Use a winter-grade washer fluid that won’t freeze in colder temperatures. Replace your wiper blades every 6–12 months, or sooner if you notice streaking or squeaking.
4. Check Your Cooling System
Even in mild winters, engines still need to be properly cooled to prevent damage. Your radiator should have the correct mix of coolant and water to protect against both freezing and overheating.
Pro Tip: A 50/50 mix of coolant and water is generally suitable for most vehicles. Check your owner’s manual for the recommended mix, and inspect hoses and the radiator for any signs of leaks.
5. Ensure Your Lights Are Working
Shorter days and gloomy weather mean your lights play a bigger role in keeping you visible. Make sure all your exterior lights are working correctly.
Pro Tip: Clean your headlights regularly to maximise brightness, and consider upgrading to brighter halogen or LED bulbs. Don’t forget to check your brake lights and indicators too as they’re often missed.
6. Prepare for Wet Roads
Slippery roads are common in winter, so your car’s brakes and suspension need to be in good condition. If your car doesn’t feel stable in the wet, it could be a warning sign.
Pro Tip: Have your brake pads and brake fluid checked by a professional. If your car feels bouncy or unsteady, get the suspension looked at as it’s better to catch any issues early.
7. Keep Your Car Clean
Mud, grime and road salt can build up on your car during winter, leading to rust or paint damage over time. Keeping your vehicle clean helps protect it.
Pro Tip: Wash your car regularly, paying special attention to the underside and wheel arches where grime tends to build up. You might also consider an underbody sealant for extra rust protection.
Why Winter Prep Still Matters in New Zealand
While our winters might not be as harsh as elsewhere, they can still take a toll on your vehicle. From slick roads to foggy mornings, a bit of seasonal maintenance can go a long way. With these easy tips, your car will be ready for winter. You’ll not only keep your car in good shape but also stay safer on the road, and potentially save yourself a few costly repairs down the line!
