How to maintain a car?

1. The air pre-filter can be used to remove impurities in the tube by pinching open the duckbill-shaped tube opening. 2. Air filter: Take out the filter element from the air filter and remove impurities. Pay attention to the tightness of all connections during installation. 3. Wiper and spray washer devices. The condition of the wiper blades should be checked frequently. When it is found that the wiper blades are not in good contact with the windshield, they should be replaced in time. 4. Battery During maintenance, the battery shell should be kept dry and clean to avoid leakage. When liquid is lacking, it is strictly prohibited to replenish electrolyte, mineral water, or tap water. It is strictly prohibited to knock on the terminal posts. 5. Tires: Always check whether the tire pressure meets the standards. It is strictly prohibited to install inner tubes in tires or use tires with inner tubes. 6. Vehicle exterior: Do not dry wipe the vehicle body, and do not use gasoline, kerosene, trichlorethylene, strong alkaline water, alcohol, etc. to scrub the paint surface and plexiglass surface.

Car owners should pay attention to abide by the "Maintenance Manual", especially some items that are easily overlooked, and must be re-recognized. Today, private cars are gradually becoming the market The protagonist, the car owner's maintenance concept is also established. Just like people will have regular physical examinations even if they are not sick, the concept of "7 minutes to nourish and 3 minutes to repair" when using a car is becoming increasingly popular. It's like organizing housekeeping in the army: quilts should be folded into 7-to-3 layers. New car maintenance should be sufficient. When the first warranty period is reached, most car owners will follow the manufacturer's regulations and go to a special service station for maintenance. This is because most car manufacturers New cars are offered free oil changes for the first time. For example, Shanghai General Motors will provide several free engine oil and oil filter replacement services during the warranty period. However, there are also a small number of car owners who neither consult the staff nor read the "Maintenance Manual", so there are also examples of missing out on the first insurance. Since it is a new car, if the car owner misses the first warranty, it will only cause the engine oil to turn black and dirty, which will not cause any serious consequences. However, it is still recommended that the car owner do the first warranty because the new car is in a running-in state and the mechanical parts are running in. , the demand for lubricants will be relatively high, and this is the significance of first insurance. Replace brake pads between 40,000 and 60,000 kilometers Relatively speaking, second warranty is very important. The project involves the inspection and maintenance of as many as 63 items in eight parts including the engine, automatic transmission, air-conditioning system, steering system, braking system, suspension system, body part, and tires. In addition, it also includes quality inspection test runs. It can be seen that after such a large number of inspections and maintenance, the entire car condition will obviously enter the best state, and the safety of driving can be best guaranteed. Now we will select some of the key projects and introduce them. Generally speaking, brake pads need to be replaced when the vehicle has traveled 40,000 to 60,000 kilometers. For car owners with poor driving habits, the replacement trip will be shortened accordingly. For example, if a car owner sees a red light ahead, refuels instead of taking off the gas, and then brakes to wait for the green light to pass, this is such a habit. In addition, if the car owner does not perform maintenance, it is impossible to detect that the brake pads are thinning or completely worn out in time. If the worn brake pads are not replaced in time, the vehicle's braking force will gradually decrease, threatening the safety of the car owner, and the brake disc will also be worn, and the car owner's maintenance costs will increase accordingly. Pay attention to tire wear signs. Among the tire maintenance items of the second warranty, one of them is tire rotation. The spare tires of some brands of vehicles are very different from the tires, and the size is too small (some have iron wheels). Because of this, it even made a joke. There was once a customer who complained that a dealer was cheating by using a motorcycle tire as a car tire to defraud 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, tire maintenance items also include adjusting air pressure. Car owners should not underestimate tire pressure. If the tire pressure is too high, it will easily wear the middle part of the tread. It is worth reminding that it is difficult for car owners to accurately measure tire pressure without relying on a pressure gauge. Daily use of tires requires some details.

If you pay attention to the distance between the tire tread and the wear mark, generally speaking, you should replace the tire with a new one if the distance is within 2-3mm. For another example, if a tire is punctured, if it is on the sidewall, the car owner must not listen to the advice of a quick repair shop to repair the tire, but should replace the tire immediately, otherwise the consequences will be serious. Because the sidewall is very thin, it will not be able to withstand the weight of the vehicle after repair, and a tire blowout is likely to occur. The "three compartments" must be replaced frequently. The "three compartments" are commonly referred to as the fuel filter element, air filter element and oil filter element. In the second maintenance engine maintenance project, the first item is to replace the three compartments. The purpose is of course to make it clean. Engine oil and fuel to protect the normal operation of the engine. If the car owner insists on not changing the "three grids", the power of the car will be affected to some extent. For example, if the fuel filter is not good, the nozzle will be clogged. Then the car owner will spend more money to clean the nozzle. And if the engine oil becomes dirty, the situation is also very bad. Because the function of engine oil is not only lubrication, but also cleaning, cooling, noise reduction, sealing and other functions. Loose ball heads affect steering. Checking whether the tie rods and ball heads are damaged is an important part of the steering system maintenance project. The ball head becomes loose, the free travel of the steering wheel becomes larger, and the steering becomes inaccurate. If the car owner is not aware of the problem, and the situation develops to the end, once the ball head falls off, the car will completely lose direction. If you are driving at high speed, you can imagine the serious consequences. Light inspection improves driving safety. Unless the headlights or the car has the lighting fault display function of a luxury car, it will be difficult for the car owner to find problems with the brake lights and turn signals. I believe everyone can understand the importance of turn signals and brake lights in driving safety without any introduction.
