How to maintain the car?

First, the air pre-filter can remove impurities in the pipeline by pinching the duckbill nozzle by hand. Second, the air cleaner takes the filter element out of the air cleaner to remove impurities. Pay attention to the tightness of all joints when reassembling. Third, the wiper and spray washing device should always check the condition of the wiper blade, and replace it in time if it is found that the wiper blade is not in good contact with the windshield. Four, the battery in maintenance, should keep the battery shell dry and clean, to avoid leakage phenomenon. When the liquid is insufficient, it is forbidden to replenish electrolyte, mineral water and tap water. Do not knock on the terminal. Five, the tire should always check whether the tire pressure meets the standard. It is forbidden to install inner tubes in tires or use tires with inner tubes. 6. Do not dry clean the exterior of the vehicle, and do not scrub the paint surface and plexiglass surface with gasoline, kerosene, trichloroethylene, strong alkali water and alcohol. When using the high-pressure cleaning machine, do not aim directly at the transmission, steering mechanism, radiator and engine compartment. Do not scrape the asphalt stains on the car body and the asphalt stains or gasoline stains on the bumper, and do not use gasoline or fabric to remove the stains. Answer time of automobile seat cover monopoly 2008-04-26 13: 17 There are many reports on automobile maintenance projects, and the car mainly pays attention to the maintenance manual, especially some easily overlooked projects. Today, private cars have gradually become the protagonist of the market, and the maintenance concept of owners has also been established. Just as people have regular physical examinations even if they are not sick, the concept of "7-point maintenance, 3-point maintenance" for cars has become more and more popular. It's like tidying up the house in the army: it takes 7 minutes and 3 minutes to fold the quilt. The maintenance of the new car needs to be done Most car owners will go to the special service station for maintenance according to the manufacturer's regulations when they arrive at the first warranty period, because most car manufacturers have implemented the preferential policy of free oil change for new cars. For example, Shanghai GM will provide free engine oil, three filters of engine oil and free replacement service several times during the warranty period. However, there are also a few car owners who neither consult the staff nor read the maintenance manual, so there are also examples of missing the first insurance. Because it is a new car, the owner missed the first insurance, but the oil turned black and dirty, which will not cause any serious consequences. However, it is recommended that the owner do the first insurance, because the new car is in a running-in state and the mechanical part is running-in, which will have higher demand for lubricating oil. This is the meaning of being the first insurance. 40,000-60,000 kilometers to replace the brake pads. Relatively speaking, the second insurance is very important. The project involves the inspection and maintenance of up to 63 projects in eight parts, including engine, automatic gearbox, air conditioning system, steering system, braking system, suspension system, body part and tires. In addition, it also includes quality inspection and debugging. It can be seen that after so many tests and maintenance, the condition of the whole vehicle will obviously enter the best state, and the driving safety can be best guaranteed. Now select a few key projects to introduce. Generally speaking, the brake pads will be replaced when the vehicle travels 40,000-60,000 kilometers. For car owners with bad driving habits, the replacement trip will be shortened accordingly. If the owner sees the red light ahead, but refuels instead of collecting oil, and then drags the brakes and other green lights to let go, it belongs to this habit. In addition, if the owner does not do maintenance, it is impossible to find that the brake pads are thinned or completely worn in time. If the worn brake pads are not replaced in time, the braking force of the vehicle will gradually decrease, threatening the safety of the owner, the brake disc will also wear, and the maintenance cost of the owner will increase accordingly. Pay attention to the tire wear marks. One of the tire maintenance projects is tire transposition. The spare tire and tire size of some brands of vehicles are quite different, and the size is too small (there are also iron wheels). Because of this, there is also a joke. Once, a customer complained that the dealer "stole the column" and used a motorcycle tire as a car tire to cheat money. If a spare tire is used in an emergency, the owner should replace it with a standard tire as soon as possible. In addition, the tire maintenance project also includes adjusting the air pressure. For tire pressure, the owner should not be underestimated. If the tire pressure is too high, it is easy to wear the middle of the tread. It is worth reminding that it is difficult for car owners to measure tire pressure intuitively and accurately without relying on barometer. There are some details about the daily use of tires. If you pay attention to the distance between the tread and the wear marks, generally speaking, the tire should be replaced if the distance is within 2-3 mm, and if the tire is punctured, if it is the sidewall, the owner must not listen to the advice of the quick repair shop to repair the tire, but should change the tire immediately, otherwise the consequences will be very serious. Because the sidewall is very thin, it will not bear the weight of the car after repair, and it is easy to puncture. "Three grids" should be replaced frequently. "Three grids" are commonly known as fuel filter, air filter and oil filter. In the second maintenance project of the insurance engine, the first one is to replace three grilles. The purpose is, of course, to clean the oil and fuel, so as to protect the normal operation of the engine. If the owner insists on not changing the "three grids", the power of the car will be affected more or less. Such as fuel grille, if the gasoline is not filtered well, it is likely to cause nozzle blockage. Then the owner will spend more money to clean the nozzle. If the oil gets dirty, the situation is not good. Because the function of engine oil is not only lubrication, but also cleaning, cooling, noise reduction and sealing. Loose ball head affects steering. Checking whether the tie rod and the ball head are damaged is an important part of the steering system maintenance project. The ball head is loose, the free stroke of the steering wheel becomes larger, and the hitting direction becomes inaccurate. If the owner doesn't realize the problem, the situation will eventually develop. Once the ball head falls off, the car will completely lose its direction. If it is driving at high speed, the consequences can be imagined. Lighting inspection improves driving safety. Unless the headlights or cars have the function of showing the light failure of luxury cars, there are problems with the brake lights and turn signals, and it is difficult for the owners to find them themselves. I believe that you can understand the importance of turn signals and brake lights in driving safety without introduction.
