In winter, when the temperature becomes lower and colder, both people and things will be affected by the bad weather. Friends who go out, especially driving, must pay attention to driving safety. At the same time, do a good job in winter vehicle protection to avoid output problems. Here are a few tips for winter vehicle maintenance.
1. If the windscreen wipers drive northward, in the northern area, if you go out in the morning and find that the windscreen wipers are stuck by snow water on the windshield, do not wash them directly with hot water, which is easy to crack the windows and deform the windscreen wipers due to the temperature changes. The correct way is to turn on the air conditioner to the hot air, the blowing mode is the front windshield, and wait for the wiper to turn on naturally.
2. In winter, the cooling system shall regularly check whether the water tank, water pump, belt, water pipe, make-up tank and other components work normally. If there is any damage or failure, it is better to repair or replace them in time. Otherwise, a bucket of antifreeze may be wasted for a small water pipe. In particular, some cars have high water temperature in summer, so the repairmen remove the thermostat. Although it can solve the problem in summer, it will reverse in winter.
3. If the warm air has been placed for a summer, it will often fail. It's better to first try to see if there is hot air, if there is abnormal noise in the fan operation, and if the air duct is unobstructed. Sometimes, the problem is that the antifreeze in the heating water pipe does not flow for a long time, and the condensation blocks the circulation pipeline. Although it does not affect the driving, the maintenance is very troublesome.
4. Antifreeze many southern drivers generally do not check the habit of antifreeze, but when driving to the north, we should pay attention. Check whether there is liquid shortage or deterioration, and supplement or replace it in time if necessary. Antifreeze seems to be a small matter, but it has a great impact on the car. If it is light, it will block the pipeline, if it is heavy, it will corrode and damage the cylinder block. So choose and use antifreeze carefully. First, don't mix it up. Second, don't use fake and inferior products. In addition, generally speaking, antifreeze should be changed once every two years. Before replacement, it is better to wash the cooling system with clean water.
5. Check whether the label of the engine oil is low temperature and whether it is missing or deteriorated. In winter, the engine oil is too thick, which will affect the starting and increase the wear of the parts. At the same time, too thin hot engine oil will reduce the lubrication and sealing performance. Choose the high-quality compound oil suitable for winter. If it's time to change the oil, it's better to change it before it gets cold.
6. The basic condition for safe driving is to keep the windshield clear. The wipers shall be cleaned regularly in winter, and the windshield can be cleaned in rainy days. In addition, some windshield deicing agent can be added to the glass water. When the windshield freezes, spray the glass water, and the ice will melt. Unlike ordinary glass water, it will be more and more troublesome to spray when it freezes.
7. Before winter, you'd better put a protective film on your car. The paint coating or mirror glaze containing Teflon polymer can resist the erosion of acid rain fog. When driving to the north, the road will be sprinkled with salt water after snow, and the salt water splashed on the car body will do great harm to the car paint. Pay attention to cleaning.
8. Chassis in winter, the car chassis is always dealing with rain directly, which is easy to rust. The speeding tires will throw mud and water on the car chassis. After the rain, the chassis of the car began to rust. So, it's best to spend some time before winter to give the chassis a antirust care.
9. The storage battery is most afraid of low temperature. The capacity of storage battery in low temperature environment is much lower than that in normal temperature. Therefore, before the cold season, it is necessary to supplement the electrolyte of the battery and adjust the specific gravity of the electrolyte. At the same time, clean the terminal of the battery, and apply special grease to protect it, so as to ensure reliable start and prolong the battery life. If the vehicle is not used in the open air or cold storage for several weeks, the battery shall be removed and stored in a warmer room to prevent the battery from icing damage.
10. The tire rubber will be hard and relatively brittle in winter, and the friction coefficient will be reduced, so the tire pressure should not be too high, but not too low. The external air temperature is low, the tire pressure is too low, and the soft tire can accelerate the aging seriously. In winter, it is necessary to clean up the inclusions in the tread regularly, try to avoid using the tires that have been mended more than once, and replace the tires with big wear and different tread patterns of different brands. The internal and external wear of tyres are quite different. In order to ensure safety and reduce wear, the tyres should be replaced regularly.
