Take the "Last Bus" for "Aiku" winter maintenance.

Usually, cars are prone to failure in winter, so they should be actively maintained in autumn. You can't sharpen your knife when you get cold feet, otherwise it will damage the car and bring you unnecessary losses and troubles. Some car owners are not very clear about how to maintain their vehicles in different seasons, and even think it is a burden.

Q: Can you focus on other precautions for seasonal maintenance of vehicles?

A: In addition to antifreeze, the lubrication requirements for automobiles are higher in winter. Due to the cold temperature in winter, the greater the viscosity of engine oil, the greater the engine resistance. Therefore, if summer engine oil is used or the engine oil is improperly selected, or the engine oil is used for a long time, the color is black, and the adhesion is poor. , should be replaced in time, otherwise it will not only make the cold start of the car difficult, but also seriously aggravate the serious wear and tear when the engine starts. Please pay more attention to the difficulty of cold start of vehicles in winter. If there is too much carbon in the throttle, it will often cause this problem. Therefore, it is best to thoroughly clean the throttle and other related "channels" during seasonal maintenance to avoid the embarrassment of cold start. In addition, when the cold start is difficult, don't start hard one after another. Impatience and willfulness won't help. A better method is to control the startup time within 8 seconds. If the startup is unsuccessful for three times, stop for at least 30 seconds before continuing to try to start, so as not to consume your battery excessively.

Q: How to maintain the brake system and battery?

Answer: Before entering the winter, pay attention to whether the electrolyte in the battery is insufficient. In general, it is better to immerse the electrode plate 10 mm ... The ratio of electrolyte is important to be tested by professionals, and "rough estimation" cannot be taken lightly. However, if the battery is insufficiently charged and its specific gravity is too low, it is easy to crack in the cold. Therefore, it is related to life and vehicle safety, so we must always pay attention to whether the brake fluid is sufficient and whether the quality is getting worse. If necessary, it should be supplemented or replaced in time to keep it within the normal range. At the same time, pay attention to whether the brake is weak, running off, the pedaling force of the brake pedal at high speed and the position of the wheel locking point when braking. If necessary, clean the lines of the brake system. After the use of the whole summer, the free stroke of the clutch and the tightness of the hand brake should be adjusted to the best range. In addition, after rain and snow, if you stop at night and hold the handbrake, the brake disc may be frozen by accumulated water the next morning. Therefore, if you stop for a long time in rainy and snowy weather, you should use the handbrake less and find two bricks to pad the front and rear wheels to prevent the brake disc from freezing.

Q: Actually, there is tire maintenance related to the brake system. What are the simple and effective methods?

A: We should also take precautions against large areas of ice and snow. Because rubber, metal, plastic and other materials will become hard and brittle at low temperature, compared with other seasons, it is easy to leak and puncture. Coupled with the wet and bumpy road surface, the friction coefficient between the tire and the ground is greatly reduced, and the control system of the vehicle is correspondingly bulky, and the driving road feeling is weakened. If not handled properly, the vehicle may slip or inertia rear-end collision. Therefore, four-wheel alignment test in special maintenance station can ensure its stability. At the same time, the inclusions in tire tread are often cleaned in winter, and some sharp ironware is difficult to remove. Professional maintenance technicians should be asked to remove them with special tools. Similarly, try to avoid using tires that have been mended more than once. For tires of different brands, patterns and sizes, or tires with too shallow tread, large wear surface and cracks, you need to go to the 4S shop to replace them in time. Usually, you should also check the tire pressure diligently. If conditions permit, it is best to park the vehicle indoors. If you can only park outdoors, you should also choose a sunny, sheltered, flat and dry place to park. This is beneficial to the maintenance of Aiku and its four legs.
