While Australia's winters may not be as harsh as those in the northern hemisphere, cooler temperatures, increased rainfall, and fog can still present challenges for drivers. Preparing your vehicle for winter conditions is essential to ensure safety, reliability, and performance during the colder months. Here are our top winter maintenance tips specifically for Australian drivers.

Check Your Battery

Cold weather can reduce battery capacity, making it harder for your engine to start. As temperatures drop, your battery needs to work harder, which can expose underlying issues that might not be apparent during warmer months.

Have your battery tested before winter sets in, particularly if it's more than three years old. Look for signs of corrosion on the terminals and ensure connections are tight. Consider carrying jumper cables as a precaution, especially if you live in areas with particularly cold winters like Canberra, Hobart, or the Australian Alps.

Inspect Your Tyres

Wet winter roads reduce traction, making proper tyre condition even more critical for safety. Check the following:

• Tyre pressure – Cold weather causes pressure to drop, so check pressure when tyres are cold and adjust according to manufacturer specifications
• Tread depth – The legal minimum in Australia is 1.5mm, but 3mm or more is recommended for wet conditions
• Uneven wear – This could indicate alignment or suspension issues that should be addressed before winter
• Spare tyre – Ensure it's properly inflated and in good condition

If you frequently drive in mountainous regions of Victoria or New South Wales where snow is possible, consider whether you need specialised winter tyres or snow chains.

Test Your Heating and Defrosting System

A functioning heating system is essential for comfort and safety in winter. Test your car's heating system before the cold weather arrives to ensure it's working properly. This includes checking that:

• The heater produces warm air at an adequate volume
• The defrosters for front and rear windows work effectively
• Climate control settings operate as expected

If your windows fog up frequently or your heating system isn't performing well, have it inspected by a professional. This could indicate low coolant levels or other issues that should be addressed promptly.

Replace Wiper Blades and Top Up Fluids

Clear visibility is crucial during winter's increased rainfall. Wiper blades typically need replacement every 6-12 months, and winter is an ideal time to install new ones. Check that your windscreen washer fluid is topped up and consider using a formula with anti-freeze properties if you're in a particularly cold region.

Also check and top up other essential fluids:

• Engine oil – Cold weather can make oil thicker and less effective
• Coolant/antifreeze – This prevents your engine from freezing in extreme cold
• Brake fluid – Essential for safety on slippery winter roads
• Power steering fluid – Ensures responsive handling in all conditions

Check Lighting and Electrical Systems

Winter means shorter days and reduced visibility, making proper lighting critical. Check that all exterior lights are functioning correctly, including:

• Headlights (both high and low beam)
• Fog lights (if equipped)
• Brake lights
• Turn signals
• Hazard lights

Clean headlight lenses if they appear foggy or yellowed, as this can significantly reduce light output. Consider upgrading to higher-performance bulbs if you frequently drive on poorly lit roads.

Consider an Oil Change

If you're due for an oil change, winter is a good time to get it done. Some mechanics recommend switching to a lower viscosity oil during winter months as it flows more easily in cold temperatures, reducing engine wear during cold starts. Check your owner's manual or consult with a professional mechanic for the best recommendation for your specific vehicle.

Prepare an Emergency Kit

While being stranded in snow is rare in most parts of Australia, being prepared for a breakdown in cold, wet conditions is still important. Consider keeping these items in your car during winter:

• Waterproof jacket or poncho
• Torch with extra batteries
• First aid kit
• Blanket
• Bottled water and non-perishable snacks
• Phone charger
• Basic tools
• Warning triangle

Schedule a Pre-Winter Service

The best way to ensure your vehicle is winter-ready is to schedule a comprehensive service with a qualified mechanic. A professional can inspect systems that are difficult for the average driver to check, such as:

• Braking system
• Exhaust system
• Battery load test
• Heating and cooling system
• Suspension components
