Car maintenance experts said that some people thought that they were maintaining the car, but in fact they accidentally damaged the car. Looked at the following error maintenance method, you also come to check the number.
Imported tires - not applicable
Some people buy tires and particularly like to emphasize "imports." The most fatal flaw in the new tires pushed abroad is that it is not applicable. The smooth road surface in Europe is quite different from the road conditions in Beijing's Second Ring Road and Third Ring Road. The tires suitable for European road conditions are difficult to perform in Beijing. In particular, the impact resistance of the sidewall is obviously not acclimatized, just like wearing Italy. Brand-name leather shoes take the stone road in general, and the sidewalls are inevitable. After the domestic joint venture production of some foreign brand tires, a layer of cord fabric was added to the side of the tire according to the domestic road conditions, which greatly enhanced the impact resistance of the sidewall. Therefore, the tires produced by the joint venture can completely replace the imported goods in terms of performance.
New battery is not charging - shorten life
The first charge of the battery is called the first charge, and the initial charge has a great impact on the battery life. If it is not charged, it will be directly used by adding "water". The capacity of the battery will not be high and the life will be shortened. If it is directly charged, the life will be shortened. Usually, the initial charge of the battery is installed after the filling of the electrolyte, and charging with a small current for about one hour.
In-car equipment is free to add --- affect driving safety
Private cars are the home of mobile owners. It is understandable to pursue passenger comfort and luxury. However, some car owners do their own to install various equipment in the car. This kind of modification, if not handled properly, will bring disadvantages to the convenience of car performance and handling. Impact, easy to leave behind or affect driving safety.
Cooling water temperature is too low - wear engine
In summer, the weather is hot. Some drivers want to prevent the engine temperature from being too high. The temperature of the cooling water is required to be as low as possible. Some drivers simply remove the thermostat for the purpose of cooling. These are all wrong.
In fact, the automobile engine is both hot and cold. If the temperature of the cooling water is too low, the fuel combustion will deteriorate, the fuel consumption will increase, the wear will be aggravated, the viscosity of the oil will increase, and the engine power will decrease. Tests have shown that when the temperature of the cooling water is 40-50 degrees Celsius, the engine wear increases by 60%-80%, the power is reduced by 25%, and the fuel consumption is increased by 8%-10%. Therefore, the temperature of the engine cooling water is not as low as possible, and should generally be controlled between 80-90 degrees Celsius.
Water tank "opening pot" speed water - cylinder cracking
In the summer, the weather was hot. Some drivers saw the phenomenon of “opening the pot†when they saw the water tank. They worried that the engine temperature would rise again and immediately extinguished the fire and added water. This is wrong, and it is very likely that the cylinder head will crack due to sudden cold.
If you encounter the water tank "opening the pot", the general correct method is: stop immediately, let the engine keep idle and idle to continue to dissipate heat; at the same time open the engine cover to improve the heat dissipation speed. After the temperature of the cooling water is lowered, the engine is turned off. At this time, if the cooling water is insufficient, it should be added slowly to prevent the cylinder head from cracking due to sudden cold.
Long-term no car or short-distance car - damage to the machine
Although some people have become car owners, they usually drive when they are not willing to drive. They only drive out when they are on vacation. In fact, such a car is very hurtful. The surface of the transmission parts such as the engine and the gearbox will rust due to the direct contact with the air, and the battery will also have a long service life due to long-term natural discharge. The best way is to run the car every few days and run for thirty or forty minutes.
In addition, the car is always moving but not far away, which is an important reason for the injury. The on-board components wear most during the engine's start-to-stabilization phase. The power consumed to start a car's battery also takes about 20 minutes to make up. This car habit can easily cause the car to get out early.
