After the beginning of autumn, the temperature difference is large, noon heat, cool sooner or later. The human immunity and disease resistance are declining. It is easy to catch a cold when it cools a bit. Therefore, it is necessary to appropriately increase or decrease clothes according to climate changes to prevent cold and colds. The same applies to cars, and they experience high temperatures and rain throughout the summer. Thanks to the horses, people are still in need of horses. When the weather suddenly turns cold, the "immunity" must be discounted. Therefore, as a car owner, you must not forget to do seasonal maintenance for your car.
Interior needs to be completely sterilized and cleaned
After a long and hot summer, the carpet and floor glue and other interiors laid in the car have been covered with dust and bacteria have developed. Under the catalysis of high temperatures, these dust and bacteria can easily give off an unpleasant smell; Frequently opening the windows can dispel these odors. After the beginning of autumn, the weather gradually cools down. The windows in the car are also closed. The air in the compartments begins to become cloudy, and odors and bacteria can harm people’s health. If so, Continuing, in the winter, the fluidity of the carriages will definitely become very poor, so we still do a thorough interior sterilization and cleaning for the cars in this summer and fall.
Chie Nepu automotive maintenance expert Ming De introduced that the general interior cleaning and maintenance including seat, trunk, carpet, floor glue, dashboard, door panels, etc., cleaning, sterilization, deodorization and polishing maintenance, as long as there is a car Sauna car beauty shop has this business, the price is generally around a few hundred dollars. Of course, the price also depends on the cleanliness of the original car and the size of the car. If your car is equipped with leather seats, the cool breeze, the leather is easy to dry, then you may wish to do leather maintenance, keeping the skin shiny and soft. Some of the plastic parts in the car have been exposed to the sun's rays in the summer, and some of them may have been aged and stained. These plastic parts can also be restored with a polishing solution. The choice of cleaning fluid and polishing fluid in the cleaning and maintenance process is critical. The cleaning fluid must be chosen to be neutral. If there are too many alkaline components, it is easy to burn the leather and velvet on the seat. Although the alkaline cleaning solution was clean after cleaning, it has been unknowingly causing damage to your car. There is a kind of inexpensive coating on the market. It is slimy and greasy. This coating is fake and cannot really polish or maintain it. In order not to be deceived, it is recommended that you go to a professional and regular car beauty shop to do interior sterilization cleaning and maintenance projects.
Air conditioning filter to clean and replace
In summer, vehicles often wading, so that the lower part of the air-conditioning condenser is likely to be stained with sediment. After a long time, sediment and dust are heavily deposited, which will seriously affect the service life of air conditioners. Therefore, in the summer and autumn, certain To check the maintenance of air conditioning.
“The service life of auto air-conditioning depends largely on whether it can be properly maintained.†Zhang Liwei, Toyota’s technical director of Sanyuanqiao, Beijing, said that during the use of automotive air-conditioning systems, air evaporates in blowers and refrigeration systems. Boxes, small tanks for warm air systems, and air ducts flow. As long as the air conditioner blower is turned on or the air intake mode is selected to be circulated indoors, air will enter the above system regardless of whether or not the refrigeration unit is used. These air will accumulate a lot of dust, moisture, bacteria and other foulants on the surface of the above device during the cycle. As time goes on, it will breed molds and other bacteria and cause odors. It will cause damage and allergic reactions to the human respiratory system and skin. It will directly affect health, and the air-conditioning system itself will also have problems such as poor cooling effect and small air volume. During the process of air-conditioning system use, dust and bacteria will gradually accumulate on the air-conditioning filter. When the air-conditioning system reaches a certain level, the air-conditioning system will also experience the above-mentioned series of failures and require regular maintenance to maintain good air. Adjust the quality. Therefore, at the time of summer and autumn, it is necessary to clean and regularly replace air-conditioning filters.
Antifreeze replaces tap water
In summer, many owners like to use tap water instead of antifreeze. After the beginning of autumn, the weather gradually cools. Once the cold air arrives and the temperature drops suddenly, it may affect the normal operation of the car cooling system. Therefore, the owner should promptly release the water tank. Tap water to use antifreeze. Normally, the replacement period of antifreeze is 2 years, so if your car has been using antifreeze in summer, you don't need to change it. In addition, the engine cooling system should be cleaned before replacing the antifreeze.
Under normal conditions, anti-freeze fluids need to be replaced when the car travels 3000 to 4000 kilometers. There are certain ways to replace and refill antifreeze:
First, unscrew the tank lid, open the tank drain valve, and release antifreeze. Then, a rubber tube connected to the water pipe is inserted into the tank water inlet, the tap is opened, and the tap water continuously flows through the engine cooling system. During the flushing operation, the engine should be idling and the above operation should be maintained until the tank releases fresh water. At this time, turn off the tap and wait until the water in the cooling system is drained. Then, close the water tank drain valve and rinse the antifreeze liquid tank. Add antifreeze from the tank water inlet to fill the tank with antifreeze. Unscrew the reservoir cap, add antifreeze, and reach the "FULL" mark, taking care not to exceed the "FULL" mark. Cover the tank lid and reservoir cap and tighten. Start the engine, idling for 2 to 3 minutes, and unscrew the tank lid. At this time, the cooling system will eliminate some of the air and the antifreeze level will decrease. At this time, antifreeze should be added to make the tank full. Finally, cap the tank and tighten it. It should be noted that when the temperature of antifreeze is high, do not open the water tank cover or drain valve to avoid burns.
Peng Haitao, the blue-star cleaning company in Beijing, reminded owners not to use water instead of antifreeze, because experimental results have confirmed that the average corrosion rate of various metals in water for automotive cooling circulation systems is 50 times that of antifreeze.
Sound precautions against moisture and heat
Professionals of Siemens VDO Automotive Electronics Co., Ltd. told the reporter that acoustic malfunctions generally fall into two categories: one is caused by improper use, and the other is due to the weather. Most of the new cars are now equipped with CD equipment. The factors affecting the normal work of car stereos in the late summer and early autumn are mainly high temperature and humidity. Because the car audio is installed on the upper part of the instrument panel, it is better to use the sun visor in order to avoid the sunlight. If the door and window seals are not strict, they should be replaced. Otherwise, the speakers may be easily rusted and damaged, and even cause a short circuit to burn the host. With the increase of humidity during the rainy season, there is often a layer of fog on the surface of CD recordings, which can lead to difficulties in reading the discs, and it is advisable to scrub once every time. If it is a modified CD drive, in order to avoid moisture, do not install under the floor and seat, it is best installed in the height of the body, but not in the rear windshield, the temperature is too high will cause accelerated aging of electronic components and laser heads.
In addition, during the summer and autumn, many owners are keen on self-driving activities. At this time, the most attention should be paid to dust protection. The most important part of the CD drive is the maintenance of the laser head. The laser head is also the most expensive of the fragile parts. Although the car audio has considered the problem of dust prevention in the design process, but the road conditions in the country are not very good, so the dust problem is It is particularly important. When the road conditions are poor, the windows should be closed in time; in the meantime, attention should be paid to keeping the interior clean.
