Warm water should be used for vehicle maintenance and cleaning in winter, and cold water should not be used for direct washing. Especially after the engine is warmed up, the temperature of the front of the engine is high, which causes rapid cooling with cold water cleaning, which is very unfavorable to the surface paint and cannot directly clean the engine. After washing, open the door in time to dry the water, so as to prevent the residual water at the crack of the door from freezing the door. Don't force the window to open and close when it freezes. Pay special attention to the electric window and use it after it melts naturally.
In terms of electrical appliances:
In the cold winter, the power consumption of cars is much larger than in other seasons. Before the cold winter comes, the battery of the car should be maintained to avoid worrying when it doesn't catch fire. For non-maintenance-free batteries, if they are used for a long time, they should be sent to the repair shop for thorough charging to keep the batteries in good working condition. The service life of general batteries is two to three years. If the vehicle is close to the service life, especially the automatic transmission model, it is best to replace it in advance to prevent accidents.
Maintenance instructions:
The winter maintenance of cars is mainly manifested in antifreeze, batteries, engines, tires, wipers and other aspects that require higher temperature.
The first is the battery. Always check the liquid level and specific gravity of electrolyte to keep the battery in good condition.
Second, the cleaning of dry filter elements. As we all know, most parts of China are windy and the air is dry in winter. Fine sand particles diffused in the wind enter the cylinder wall with the air in the air electronic display screen to form abrasive, which accelerates the wear of the cylinder and adheres to the led screen together with the engine oil, thus accelerating the deterioration of the engine oil. Therefore, the dust on the air filter must be cleaned and maintained every 5000 kilometers.
Third, the engine. Pay attention to check whether the engine temperature is normal, in fact, it is to check the opening of the thermostat. Whether the engine temperature is too high or too low, it will aggravate the engine wear.
Fourth, tires. Pay attention to the tire pressure of the spare tire. Check the plastic tire wall for cracks, damage or bulges. In case of the above situation, you must go to a professional maintenance station immediately.
Fifth, the wiper. If it is damaged, it must be replaced, and the windshield cleaner should be filled in the hood to maintain good sight and visibility.
Sixth, remove the frozen ice on the glass. After a cold night, cars parked outside the garage will form a thick layer of frozen ice on the glass. If you are in a hurry to go to school or work, don't thaw it with hot water. This will not only easily break the window glass and deform the wiper, but also freeze in cold weather. As soon as the hot water is poured out, it freezes immediately, which increases the difficulty. The recommended method for you is to turn the air conditioner into hot air, and the blowing mode is the front windshield until the wiper is turned on naturally. At the same time, scrape the ice slowly from the crack with a thin piece of ice. If you don't have a snow shovel, you can also scrape it slowly with a credit card.
