Winter in Poland is not only beautiful landscapes, but also a real test for your car. Low temperatures, icy roads, salt and chemicals, and extra load on every system can quickly expose even minor faults. To avoid unpleasant surprises, it is worth looking after preparing the car for winter in good time. Specialists from SerwisUA in Wrocław have prepared a complete, practical guide to get your car ready for the cold season.
🔧 1. Battery and electrical system
Frost reduces battery capacity by as much as 30%, which is why it most often fails in winter.
- Check the charge level and voltage.
- Clean the terminals of corrosion.
- If the battery is more than 4 years old — consider replacing it.
It is also worth checking the alternator and starter. If the engine is hard to start, visit SerwisUA, where our specialists will diagnose and fix the problem quickly.
🧊 2. Coolant and cooling system
Coolant should withstand temperatures down to -35°C. You need to check not only the level, but also density and cleanliness.
- If the fluid is cloudy or has sediment — a change and a system flush will be needed.
- Make sure there are no leaks from hoses or the radiator.
- Check the condition of clamps and rubber hoses.
A neglected cooling system can lead to the fluid freezing and expensive engine damage.
🚗 3. Engine oil and filters
As the temperature drops, even the best engine oil thickens. So in autumn you must:
- check the oil level and condition,
- note when it was last changed,
- check that the air, fuel and cabin filters are clean.
In winter oils with lower viscosity are recommended, for example 5W-30 or 0W-30 — they make starting easier in low temperatures.
❄️ 4. Tyres and brake system
Winter safety starts with tyres. If tread depth has fallen below 4 mm, it is time to change them.
- Fit winter tyres suited to Polish road conditions.
- Check pressure — it naturally drops in winter.
- Check pads, discs and brake fluid.
Worn brakes and the wrong tyres are the most common causes of skids and collisions on a slippery surface.
💡 5. Lighting and visibility
Short days and frequent precipitation demand excellent visibility.
- Replace bulbs if they shine more weakly.
- Check headlamp alignment.
- Fit new wiper blades and top up winter washer fluid.
Do not forget the rear-window and mirror heaters — they improve driving safety in difficult conditions.
🧰 6. Bodywork and suspension
Salt and chemicals on the roads speed up corrosion. Before winter it is worth:
- washing the body thoroughly and protecting it with wax or a ceramic coating,
- checking the underbody anti-corrosion coating,
- assessing the condition of shock absorbers, bushes and mountings.
At SerwisUA in Wrocław we will carry out a full suspension inspection, so you avoid knocks and a loss of stability on a slippery surface.
🧯 7. A winter emergency kit in the boot
Winter can surprise even the most experienced drivers. It is worth having in the car:
- a shovel and a snow brush,
- a tow rope,
- a warm blanket,
- spare washer fluid,
- a power bank or a portable jump starter.
⚙️ 8. Extra tips from SerwisUA
- Do not leave the car with the handbrake on — use a gear.
- Fill up only at proven stations, to avoid condensate in the fuel.
- If you rarely use the car, start it at least once a week.
✅ Summary
Preparing a car for winter is not only prevention, but above all a guarantee of safety for you and your family. A working battery, fresh oil, good tyres and effective lighting will give problem-free driving even in the toughest conditions.
