Appearance:

1. The northern winter is cold and dry, and cars are often attacked by ice, snow, and wind and sand, which causes the car paint to appear matte in advance. Clean the vehicle frequently and clean it in a timely manner. Waxing not only resists ultraviolet rays, but also resists corrosion from acid snow and friction.

2. Use warm water for maintenance and cleaning of vehicles in winter, and do not rinse directly with cold water. Especially after the engine heats up, the temperature of the front part of the car is relatively high. Washing with cold water will cause a rapid cooling, which is very detrimental to the surface paint, and the engine cannot be washed directly. After rinsing, open the door in time to wipe away the water stains to prevent the remaining water in the door seam from freezing and freezing the door. Do not force the windows to open or close when they are frozen. Pay special attention to electric windows. Wait for them to melt naturally before using them.

Electrical appliances:

In the cold winter, cars consume much more power than in other seasons. It is necessary to take care of the car's battery before the cold winter arrives, so as not to worry when it fails to start the fire. If the battery that is not maintenance-free has been used for a long time, the battery should be sent to a repair shop for a complete charge to keep the battery in good working condition. The average battery life is two to three years. If the vehicle is approaching the end of its service life, especially the automatic transmission model, it is best to replace it in advance to prevent accidents.

Maintenance instructions:

Winter maintenance of automobiles mainly includes antifreeze, batteries, engines, tires, wipers and other aspects that have relatively high temperature requirements.

First, the battery. Always check the electrolyte level and specific gravity to keep the battery in good condition.

Second, clean the dry filter element. As we all know, most parts of our country are windy in winter and the air is dry. The fine sand grains in the wind enter the cylinder wall with the air and form abrasives, which accelerates the wear of the cylinder and sticks to the LED screen together with the engine oil. It speeds up the deterioration of engine oil, so the dust on the air filter must be cleaned during maintenance every 5,000 kilometers.

Third, engine. Pay attention to check whether the engine temperature is normal. In fact, you are checking the opening of the thermostat. Whether the engine temperature is too high or too low, it will increase engine wear.

Fourth, tires. Pay attention to check the tire pressure of the spare tire. Check to see if there are any cracks, damage, or small bulges in the reshaped sidewall. If the above situation occurs, you must go to a professional maintenance station immediately.

Fifth, wipers. If damaged, be sure to replace it and fill up the windshield cleaner in the hood to maintain good sight lines and visibility.

Sixth, remove the ice on the glass. A car parked outside a garage will have a thick layer of frozen ice forming on the glass after a cold night. If you are in a hurry to go to school or work, do not use hot water to thaw. This not only easily breaks the window glass and deforms the wiper blades, but also increases the difficulty when the hot water is poured out and freezes immediately when the weather is cold. The recommended method for you is: turn on the air conditioner to hot air, set the blowing mode to the front windshield, and wait for the wipers to turn on naturally. At the same time, use an ice scraper to slowly remove ice from between the cracks. If you don’t bring an ice and snow scraper, you can also use a credit card to scrape slowly.

When washing your car in winter, you should pay attention to three steps:

1. Wash your car with warm water. In cold weather, dripping water often turns into ice. Therefore, the biggest taboo when washing your car is that water droplets freeze on the vehicle. The direct consequence is that the paint layer will crack. Therefore, it is best to use warm water when washing your car, rather than washing it directly with cold water. If possible, it should be done indoors. After the vehicle enters the work station, stay there for 5 to 10 minutes and wait for the engine to cool down before cleaning. Rapid cooling and rapid heating are detrimental to the paint surface.

2. Prevent water from entering keyholes and other parts.

Before washing the car, be sure to turn off the engine, close the windows and movable sunroof, and retract the antenna. Do not use a high-pressure washer to clean soft parts on the car, such as seals, hoses, tires, etc. Even a short spray cleaning can cause damage to these parts.

When flushing the car with a water hose, do not spray the water hose nozzle at the keyhole, door and trunk lid joints to avoid freezing due to low temperatures. For the door lock cylinder, you can use a special protective agent sprayer to lubricate and prevent corrosion and prevent freezing.

3. Wipe clean after washing the car. When washing the car in winter, open the door after cleaning and wipe away the water stains in time to prevent the residual water in the door gap from freezing and freezing the door. In addition, the wiper and washer devices are mainly used to clean the windshield and maintain good visibility. When the snow is too thick in winter, do not use wipers to remove snow directly. If snow or ice has accumulated on the windows and rearview mirror, the residue on them can only be removed with a plastic scraper. When cleaning, the scraper can only move in the same direction, and never scrape back and forth to prevent hard objects remaining on the glass from scratching the glass. In addition, you can use a special window cleaner or silicone remover to clean the oil, grease, wax, silicone and other dirt that appear on the car windows.

There should always be enough washing liquid in the washing liquid tank. For best washing results, use the designated washing liquid.

When filling, be careful not to mix impurities, and do not add general detergent. In order to avoid liquid freezing in winter, under cold conditions, detergent with corresponding antifreeze properties should be added.
