10 tips for car maintenance in winter

1. Wiper

If you drive north, in the northern area, if you go out in the morning and find that the wiper is stuck to the windshield by snow water, do not rinse it directly with hot water. This will easily cause the window to burst and the wiper deform due to temperature changes. The correct method should be to turn on the air conditioner to hot air, the blowing mode is the front windshield, and wait for the wiper to turn on naturally.

2. Cooling system

In winter, it is necessary to regularly check whether the water tank, water pump and belt, water pipe, water supply tank and other parts are working properly. If there is any damage or failure, it is best to repair or replace it in time. Otherwise, a bucket of antifreeze may be wasted for a small water pipe. Especially in some cars, the water temperature is too high in summer, and the repairman will remove the thermostat. Although it can solve the problem in summer, it will be reversed in winter.

3. Warm air

If the hot air is placed for a summer, it will often fail. It is best to first test whether there is hot air, whether the fan is operating with abnormal noise, and whether the air duct is smooth. The problem sometimes encountered is that the antifreeze in the heater pipe does not flow for a long time, and the condensation blocks the circulation pipeline. Although it does not affect the driving, it is very troublesome to maintain.

4. Antifreeze

Many southern drivers generally do not have the habit of checking antifreeze, but when driving to the northern areas, you should pay attention. Check for lack of fluid and deterioration, and if necessary, add or replace in time. Antifreeze may seem like a trivial matter, but it has a great impact on the car, ranging from clogging the pipelines to corroding the cylinders. So choose carefully and use antifreeze carefully, one is not to mix, the other is not to use fake and shoddy products. In addition, in general, the antifreeze should be changed every two years, it is best to rinse the cooling system with clean water before replacement.

5. Motor oil

Check whether the label is cold, missing or deteriorated. Winter cold car engine oil is too thick, it will affect the start, but also increase the wear of machine parts. At the same time, too thin engine oil will reduce the lubrication and sealing performance. To select high-quality composite oil suitable for winter. If it is at or near the prescribed oil change time, it is best to change it before the weather gets colder.

6. Windshield

Keeping the windshield clear is the basic condition for safe driving. In winter, wipe the wiper regularly, and ensure that the windshield can be wiped off in rainy days. In addition, some windshield deicing agent can be added in the glass water. When the windshield freezes, spray the glass water, and the ice will melt. Unlike ordinary glass water, spraying becomes more and more troublesome when freezing.

7. Bodywork

Before winter, it is best to add a protective film to the car body. Car paint coating or mirror glaze containing Teflon polymer can resist the erosion of acid rain and fog. When driving to the northern area, the road will be sprayed with salt water after snow, and the salt water splashed on the car body is very harmful to the paint, so pay attention to cleaning.

8. Chassis

In winter, the chassis of the car always directly deals with the rain, and it is easy to rust. The speeding tires will throw muddy water onto the chassis of the car. After the rain clears, the chassis of the car begins to rust. Therefore, it is best to spend some time before the winter to give the chassis a rust care.

9. Battery

The storage battery is most afraid of low temperature, and the storage battery capacity in low temperature environment is much lower than that at normal temperature. Therefore, before the advent of the cold season, the electrolyte of the battery should be replenished and the proportion of the electrolyte should be adjusted. At the same time, clean the terminal of the battery, and apply special grease to protect it, to ensure reliable start-up and extend battery life. If the vehicle is not used in the open air or cold storage for several weeks, the battery should be removed and stored in a warmer room to prevent the battery from being damaged by icing.

10. Tires

Tire rubber will become hard and relatively brittle in winter, and the coefficient of friction will be reduced, so the tire pressure should not be too high, but it should not be too low. The outside temperature is low, the tire pressure is too low, and the soft tire can seriously accelerate aging. In winter, it is necessary to regularly clean the inclusions in the tire pattern, try to avoid using tires that have been repaired more than once, and replace tires with greater wear and different patterns of different brands. Tire wear is very different from inside to outside. To ensure safety and reduce wear, the tire should be replaced regularly.
