Winter Car Maintenance Essentials

Why Winter Preparation Matters

The winter months pose unique challenges for vehicles. Cold temperatures, snow, ice, and road salt can all take a toll on your car's performance and safety. Taking the time to prepare your vehicle for winter conditions isn't just about preventing breakdowns—it's about ensuring your safety on the road when conditions are at their most hazardous.

According to the UK Department for Transport, there's a significant increase in road incidents during winter months, with many directly attributable to poor vehicle maintenance. A properly maintained vehicle is your first line of defense against winter driving hazards.

Essential Winter Maintenance Checks

1. Battery Check and Maintenance

Cold weather significantly reduces battery capacity. In fact, at 0°C, a battery may have only about 65% of its summer capacity. At -17°C, this can drop to just 50%.

Before winter sets in:

• Have your battery professionally tested, especially if it's more than three years old
• Clean battery terminals to ensure good connections
• Consider a battery maintainer for vehicles that aren't driven daily
• Check that the alternator is charging at the correct rate

2. Tire Inspection and Preparation

Your tires are your vehicle's only contact with the road, making them particularly crucial in winter conditions.

Essential tire checks include:

• Ensure tread depth is at least 3mm for winter driving (the legal minimum is 1.6mm, but this is inadequate for snow and ice)
• Check tire pressure weekly, as it can drop in cold weather
• Consider winter tires if you live in an area with frequent snow or temperatures regularly below 7°C
• Inspect for any damage, bulges, or uneven wear

3. Fluid Levels and Condition

All vehicle fluids are affected by cold temperatures, but some require special attention:

• Antifreeze/Coolant: Ensure it's at the correct concentration to prevent freezing (typically a 50/50 mix with water)
• Oil: Consider switching to a winter-grade oil if recommended by your vehicle manufacturer
• Windscreen Wash: Use a winter-specific formula with antifreeze properties rated to at least -15°C
• Brake Fluid: Check levels and consider a flush if it hasn't been changed in the last two years

4. Visibility Systems

Winter brings longer nights and often reduced visibility during the day as well.

• Check all exterior lights are working correctly
• Replace worn wiper blades with winter-specific ones if possible
• Clear all windows completely before driving
• Consider applying a water-repellent treatment to windscreens

5. Emergency Kit Preparation

Even with perfect maintenance, winter conditions can leave you stranded. An emergency kit should include:

• Ice scraper and de-icer
• Torch with spare batteries
• Jump leads
• Warning triangle
• High-visibility vest
• Blanket and warm clothes
• Non-perishable snacks and water
• First aid kit
• Snow shovel (in areas prone to heavy snowfall)

• Check tire pressures more frequently
• Wash your car regularly to remove road salt
• Consider treating door seals with silicone spray to prevent freezing
