How to prepare a car for Finland's harsh winter conditions: 5 essential steps
The Finnish winter is a real ordeal for a car. Severe frosts, high humidity, road salting, and rapid temperature fluctuations can cause starting problems, technical failures, and reduce driving safety. To avoid unpleasant surprises, it's advisable to prepare your car for winter in time. Here are 5 essential steps that will help keep your car reliable and safe throughout the winter season.
1. Battery and starting system check
In winter, the battery is under heavy strain. Even a slight decrease in capacity can prevent the car from starting on a frosty morning.
Things to check:
- The battery's charge level and condition
- The operation of the starter and alternator
- The condition of the terminals and connections (oxidation, looseness)
Recommendation: if the battery is over 4–5 years old, its condition should be checked, or the battery should be replaced preventively.
2. Oil change and engine inspection
Low temperatures make oil thicker, which complicates cold starts and increases engine wear.
Before winter, it is important to:
- Change the engine oil according to the manufacturer's winter recommendations
- Check the level and freeze resistance of the coolant (antifreeze)
- Check the condition of belts and seals
This reduces the engine's load and prevents the cooling system from freezing or overheating.
3. Ensuring the condition of the brakes and chassis
Salt, dirt, and moisture accelerate the wear of brake and chassis components.
When preparing for winter, it is necessary to check:
- Brake pads and discs (rotors)
- Operation of the brake calipers
- Chassis and steering components
- Wheel alignment and tire condition
Good traction and functional brakes are crucial in Finnish winter traffic.
4. Checking the heating and air conditioning system
A functional heating system increases driving comfort and improves safety by preventing windows from fogging up.
Recommended measures:
- Checking the operation of the heater and air conditioning
- Maintenance and disinfection of the air conditioning system
- Inspection of the blower and air vents
- Checking or installing an auxiliary heater (Webasto, Eberspächer)
5. Lights, glass, and winter equipment
Remember to check:
- Headlights, brake lights, and turn signals
- Headlight alignment
- Windshield wipers
- Windshield washer fluid suitable for winter use
- Condition of the windshield (chips and cracks)
Additionally, it is important to ensure that winter tires meet legal requirements and have sufficient tread depth.
