How should cars be maintained in winter?

In winter, cars can be maintained in the following ways:

1. Choose the appropriate fuel grade: In winter, when the surrounding temperature is low, gasoline in the fuel tank may develop wax deposits, preventing the vehicle from starting normally. It is recommended that owners clean the fuel tank thoroughly to remove any moisture and avoid difficulties in starting due to freezing. Alternatively, using a higher-grade gasoline can make starting easier during use.

2. Winter maintenance of the battery: Car batteries are components that are not resistant to cold. In low-temperature environments, the battery's capacity is much lower than in normal temperature conditions. During the freezing season, it is necessary to replenish the electrolyte in advance, adjust the specific gravity of the battery's electrolyte, and clean the dirt from the battery terminals.

3. Winter tire maintenance: Rubber tires harden in winter, reducing the friction coefficient. Insufficient tire pressure accelerates aging, while excessive pressure decreases the friction coefficient, compromising driving safety. It is essential to adjust tire pressure appropriately during winter use to avoid abnormal tire pressure conditions.

4. Winter Maintenance of the Engine: During winter, when the surrounding temperatures are lower, there may be instances where starting the engine is unsuccessful. It is recommended to avoid parking in windy areas and try to find higher objects to block the wind, preventing difficulties in cold-starting the engine when parked.

5. Winter Use of the Heating System: The heating system is an essential feature for driving in winter. Due to prolonged disuse, some malfunctions may occur, so it's necessary to inspect the car's heating system before use. Check whether warm air is blowing out and if there are any unusual noises. When using the heating system, there's no need to press the AC button, as the heating system utilizes recycled heat. The AC button controls the air conditioning compressor, and using it unnecessarily will increase fuel consumption.

6. Winter maintenance for the body and chassis: As winter approaches, car owners can give their vehicles a beauty treatment. With fewer car washes during winter, it's advisable to protect the car's paintwork in advance. Additionally, inspect the car's chassis. Since winter brings rain and snow, applying anti-rust treatment to the chassis is recommended.

Car maintenance varies slightly with the changing seasons, so car enthusiasts should choose different approaches based on varying climates and environments.
