[China Glass Network] In the cold winter, how to maintain the car in winter has become a topic of concern for car owners. After the vehicle has passed the warranty period, some faults will inevitably occur. Cars need "three-point repair, seven-point maintenance", which is to find and eliminate some initial, potential, and hidden faults through active inspection and maintenance.
cooling system
In the winter, it is necessary to regularly check whether the water tank, water pump and belt, water pipe, water supply tank and other components are working properly. If there is damage or failure, it is better to repair or replace it in time. Otherwise, a barrel of antifreeze may be wasted for a small water pipe. In particular, some vehicles have high water temperatures in the summer, and the repairman removes the thermostat. Although it can solve the summer problem, it will be reversed in the winter.
Warm air
After placing a warm summer wind, there will often be failures. It is better to try whether there is hot air, whether the fan is running or not, and whether the air duct is unobstructed. Sometimes the problem is that the antifreeze in the heater pipe does not flow for a long time, and the condensation blocks the circulation pipe. Although it does not affect the driving, it is very troublesome to repair.
antifreeze
Many drivers generally do not have the habit of checking antifreeze, but when driving to the north, they must pay attention. Check for lack of liquid, deterioration, and if necessary, replenish or replace. Antifreeze seems to be a trivial matter, but it has a great influence on the car. If it is light, it will block the pipeline, and the corrosion will damage the cylinder. Therefore, carefully choose anti-freezing liquid with caution. First, do not mix it. Second, do not use fake and shoddy products. In addition, in general, the antifreeze should be changed once every two years. It is better to rinse the cooling system with clean water before replacement.
Motor oil
Check if the label is low temperature, whether it is missing or deteriorated. In winter, the cold motor oil is too thick, which will affect the start-up and increase the wear of the parts. At the same time, the hot car oil is too thin to reduce lubrication and sealing performance. Use high quality compound oil suitable for winter. If it is at or near the specified oil change time, it is better to replace it before the weather gets cold.
Windshield
Keeping the windshield clear is essential for safe driving. Wipe the wiper regularly during the winter and ensure that the windshield can be scraped in the rain. In addition, some windshield deicer can be added to the glass water. When the windshield is frozen, spray the glass water, and the ice will melt. Unlike the ordinary glass water, the more it is sprayed, the more trouble it will be.
Body
Before entering the winter, it is better to add a protective film to the body of love. Car paint coating or mirror glaze containing Teflon polymer can resist the erosion of acid rain and fog. Driving to the northern region, the salt water is sprinkled on the road after the snow, and the salt water splashing on the body is very harmful to the paint. Pay attention to cleaning.
Chassis
In winter, the car chassis always deal directly with rainwater, it is easy to rust, and the flying tires will pour muddy water onto the car chassis. After the rain cleared, the chassis of the car began to rust. Therefore, it is better to spend some time before entering the winter to give the chassis a rust-proof treatment.
Battery
The battery is less afraid of low temperature, and the battery capacity in a low temperature environment is much lower than that at normal temperature. Therefore, before the cold season comes, the electrolyte of the battery should be replenished to adjust the specific gravity of the electrolyte. At the same time, clean the battery terminals and apply special grease to protect them, ensure reliable start-up and extend battery life. If the vehicle is not used for a few weeks in the open air or cold storage, the battery should be removed and stored in a warmer room to prevent the battery from freezing.
Tire
Tire rubber will harden and be relatively brittle in winter, and the friction coefficient will decrease, 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 accelerate aging. In winter, the inclusions in the tread should be cleaned frequently. Try to avoid using tires that have been replenished more than once, and replace tires with large wear and different brands. The internal and external wear of the tire is very different. To ensure safety and reduce wear, the tire should be replaced regularly.
