Keeping your car properly maintained throughout the year is essential, but during the colder winter months, regular vehicle checks become even more important. Winter weather can place additional strain on your vehicle, affecting everything from battery performance to tyre grip and visibility.
The good news is that a few simple maintenance checks can help keep your car running smoothly, improve safety, and reduce the risk of breakdowns during colder weather.
Here are our top tips for preparing your car for winter.
1. Check Your Battery
Your battery should be one of your top priorities during winter. Cold and damp weather can place a huge strain on battery performance, making it harder for your car to start.
One simple way to test your battery is by turning on your headlights before starting the engine. If the lights noticeably brighten once the engine starts, it could indicate that your battery is struggling to hold charge properly.
Winter breakdowns caused by flat batteries are extremely common, so it’s worth having your battery tested if it’s showing signs of weakness.

2. Top Up Your Antifreeze
Antifreeze is essential during winter because it prevents your engine coolant from freezing in cold temperatures.
Throughout the year, coolant is typically mixed at a 50/50 ratio of water and antifreeze, but during winter many experts recommend increasing this to around 60% antifreeze and 40% water for additional protection.
Avoid repeatedly topping up your coolant system with only water, as this can dilute the antifreeze too much and increase the risk of freezing during colder weather.
3. Inspect Your Tyres
Your tyres are vital for steering, braking, and maintaining grip — especially in wet, icy, or snowy conditions.
During winter, it’s important to check both tyre pressure and tread depth regularly. Although the legal minimum tread depth in the UK is 1.6mm, many experts recommend replacing tyres before they reach this limit, particularly for winter driving.
If you regularly drive in snow or icy conditions, winter tyres can provide significantly improved grip and handling.
4. Top Up Your Screenwash
Winter roads quickly cover your windscreen in dirt, salt, and spray, making screenwash incredibly important during colder months.
Ensure your washer bottle is topped up with proper screenwash rather than plain water, as water alone can freeze in low temperatures. Also check that your windscreen wipers are in good condition and clear the screen properly without smearing.
Keeping your windscreen clean inside and out will improve visibility considerably on dark winter mornings and evenings.
5. Check Your Engine Oil
Cold weather can affect how efficiently your engine oil flows, so checking your oil level regularly during winter is essential.
Always check the oil when the engine is cold and parked on level ground. If your oil is overdue for replacement, winter can be an ideal time to get it changed, as fresh oil helps your engine perform more efficiently in colder temperatures.
6. Test All Your Lights
With darker mornings, earlier evenings, fog, rain, and poor weather conditions, your lights become even more important during winter.
Check that all headlights, brake lights, indicators, fog lights, and rear reflectors are clean and working properly. Replace any faulty bulbs immediately and make sure lenses are clean and free from cracks.
Good visibility isn’t just about seeing the road ahead — it’s also about ensuring other drivers can see you clearly.
7. Check Your Heater and Defroster
A working heater and demister are essential during winter for both comfort and safety.
If your windows are taking too long to clear or your heater doesn’t seem very effective, check for air leaks around doors and windows, as these can allow excess moisture into the vehicle and reduce the effectiveness of your heating system.
Proper ventilation and demisting help maintain visibility and make winter driving much safer overall.
8. Carry an Emergency Kit
Winter is the perfect time to prepare an emergency kit for your car. While you may never need it, you’ll be extremely grateful to have one if you ever break down in freezing weather.
A basic winter emergency kit could include:
- A torch
- A phone charger or power bank
- Warm blankets
- A shovel
- De-icer and scraper
- A soft snow brush
- Water and snacks
- Jump leads
- High-visibility clothing
Being prepared can make a huge difference if you find yourself stranded or delayed during severe weather.
