With the arrival of winter, drivers across Brazil face difficulties caused by low temperatures, which directly affect the performance of batteries, ventilation, cooling, and lubrication systems of vehicles, requiring doubled attention to preventive maintenance.

The car battery is one of the components most sensitive to cold. During winter, its capacity to provide energy is reduced, making it difficult to start the engine. To avoid issues, it is essential to perform load and voltage tests, as well as check the validity and keep the terminals clean and properly connected. Leaving the car parked for long periods can also compromise the electrical system.

Cooling System Needs the Right Additive

Another critical point during winter is the cooling system. The radiator fluid must contain the correct ratio of additive to prevent freezing and protect the engine against overheating.
The ideal is to check the level and color of the fluid, adhere to replacement intervals, and use only products recommended by the manufacturer, as described in the vehicle’s manual.

Tires Require More Attention on Cold Days

The cold can lead to reduced tire pressure and compromise grip on the road. In regions with extreme temperatures, using winter tires is recommended to ensure traction and stability. Checking the tread condition and maintaining proper inflation are essential care during this time of year.

Proper Ventilation Prevents Foggy Windshield and Thermal Discomfort

The vehicle’s heating and defogging system needs to function properly to ensure driver comfort and good visibility. Using the air conditioning helps eliminate internal moisture, and keeping the cabin filters clean improves air quality and ventilation efficiency.

Oil Change Should Consider the Correct Viscosity

Low temperatures alter the engine oil viscosity, which can compromise the internal lubrication of parts and cause premature wear.
Therefore, it is recommended to use oils suitable for winter, adhere to replacement intervals, and wait a few minutes after starting the car before driving.

Choosing the Right Car Prevents Headaches in the Cold

In addition to routine care, choosing car models with a good reliability history is a way to avoid unforeseen events.
Regular maintenance and attention to the type of engine—whether combustion or electric—also make a difference in performance in colder climates.

And you, have you checked if your car is ready to face the colder days of winter?
