Car maintenance before winter.

Tomorrow will be beginning of winter. When the owner adds clothes to himself, don't forget to give his car a maintenance before winter. Because, with the decrease of temperature, not only the pavement becomes more difficult, but also the performance of the vehicle itself will be affected. Therefore, car owners must do a maintenance before winter to increase driving safety.

1. Repair of paint surface in advance: As mentioned in the previous article, it is rainy and foggy in autumn and winter, and the damaged paint surface is prone to corrosion if it is exposed to rain for a long time. Therefore, if the car has obvious scratches, it must be painted externally in time.

2. Replace antifreeze: antifreeze seems trivial, but it has a great impact on the car, ranging from blocking the pipeline to corrosion and damage to the cylinder block. Therefore, choose antifreeze carefully. First, don't mix. Second, don't use fake and shoddy products. Perhaps many car owners in the south rarely check this, but if you want to drive to the north in winter, you must check the antifreeze in advance.

3. Wiper inspection: Wiper is also a seemingly insignificant thing, but it plays a vital role at a critical time. It can even be said that a car can't move without it Because there is more rain and snow in winter, be sure to check whether the wiper is normal before winter. It should be noted that if you go out in the winter morning and find that the wiper is stuck to the windshield by snow water, don't wash it directly with hot water, which will easily cause the window to burst and the wiper to deform due to temperature changes. The correct way should be to turn on the air conditioner with hot air, and the blowing mode is the front windshield until the wiper is turned on naturally.

4. Chassis inspection In winter, the car chassis always deals directly with rain and is easy to rust. Flying tires will throw mud on the chassis of the car. After the rain cleared, the car chassis began to rust. Therefore, it is best to take some time to do an anti-rust care for the chassis before winter.

5. Tire inspection In the winter tire inspection, it is mainly to check the tire pattern wear and tire pressure, and clean up the stones and other sundries in the gap. When winter comes, if possible, you can also prepare a set of snow tires in advance to add a "sense of security" to driving in snowy days.

6. Battery inspection: Because the battery capacity at low temperature is much lower than that at normal temperature, we can often see that the battery normally used at normal temperature cannot be used in winter. So do a good job of battery maintenance in winter. First of all, check the storage of batteries in time. If the engine is difficult to start or after barely starting, the speed gradually decreases, indicating that the battery voltage is insufficient and needs to be recharged.

7. Car light inspection: Replace the black light bulb as soon as possible, which can reduce the frequency of changing the light bulb in winter. There are many rear-end collisions in winter, because it is easy to fog and frost in winter and the visibility is low. Therefore, whether the high-position brake light works normally is also the guarantee of driving safety in winter.

8. Inspection of heating system: It is very important that the heating system can work normally. Although the heating system is simpler than the air conditioning system, it is easy to break down after stopping for a summer. Therefore, before entering the winter, try whether there is hot air in the heating system, whether there is abnormal noise in the fan operation and whether the air duct is unobstructed. Sometimes the antifreeze in the warm air pipe will not flow for a long time, and the circulating pipe will be blocked by condensation. Be sure to go to the 4S shop or repair shop for maintenance in time.

Tips: In winter, not only the car itself is prone to failure, but also the bad weather is prone to accidents. Therefore, in addition to maintaining your car before winter, you should also prepare some emergency items in the car for emergencies.
