Not to mention novice drivers. Some old drivers still make a lot of commonsense mistakes in car maintenance. Are you still doing these 8 wrong practices? 1, under the hot sun car wash Car washing under the hot sun, sunlight hitting the car body, and focusing through the water droplets can damage the car paint, which is why the car body should be wiped clean after car washing. In addition, when the car wash must keep the appearance of the car air conditioner dry, if the car air conditioner is not accidentally wet, it will affect the life of car air conditioning. 2, waxing with a circle Many people wax the body habitually in a circle, which is incorrect. The correct method of waxing is straight line, horizontal and vertical lines alternately, and then press the last step in the direction of rainwater flow, so as to achieve the effect of reducing concentric rings of halo on the paint surface. 3, excessive oil added When the oil in the engine oil pan is insufficient, the friction between the bearing and the journal will be poor due to the small amount of oil, which will increase the degree of wear, and even cause a burnt shaft accident. However, if there is too much oil, the crankshaft shank and the big end of the connecting rod will produce violent agitation when the engine is working, which not only increases the internal power loss of the engine, but also increases the oil splashed on the cylinder wall, resulting in burning oil failure. Therefore, the oil in the oil sump of the engine should be controlled between the upper and lower scoring lines of the oil dipstick. 4, the bolt is too tight There are many fasteners on the car that are connected with bolts and nuts. It should be ensured that it has enough pre-tightening force, but it cannot be tightened too tightly. If the tightening is too tight, on the one hand, the connection member will be permanently deformed under the action of external force; on the other hand, the bolt will be permanently deformed by tension, the pre-tightening force will be reduced, and even a sliding buckle or breaking phenomenon will occur. 5, fan belt too tight Summer temperatures are too high, and some drivers think that raising the tightness of the fan belt can improve the cooling effect of the engine. Therefore, the tightness of the fan belt is constantly increased, causing the fan belt to become tight. It is not true that this is wrong. The fan belt should be kept tight and tight, because over-tightening will lead to excessive bearing load, increased wear and tear, increased power consumption, and will also cause the water pump shaft to bend, the belt will be stretched and deformed, and the service life will be shortened. 6, look for imported tires Some people like to buy tires particularly like to emphasize "import." However, one of the most fatal flaws for domestic users is the inapplicability of new tires that have been introduced abroad. On the contrary, some foreign brands' tyres have been added to the tires by a layer of cord fabric after domestic joint venture production according to the domestic road conditions, which greatly enhances the impact resistance of the sidewalls. The tires produced by the joint venture can be completely replaced in terms of performance. Imported goods. 7, the new battery is not charging The first charge of the battery is called the initial charge, and the initial charge has a great influence on the service life of the battery. If it is not recharged, it will be directly used when adding “waterâ€. The capacity of the battery will not be high and the service life will be shortened; if it is directly charged, it will also shorten the life. Usually, the initial charge of the battery is performed after charging the electrolyte and charging it with a small current for about 1 hour. 8, long-term parking without Some people are not willing to use the car after the car, only to drive out to play when the holiday, in fact, such a car is also very hurt the car. Parts of the transmission such as the engine and the gearbox are rusted due to their direct contact with the air, and the battery will also affect the service life due to long-term natural discharge. The best way is to run the car every few days and run for thirty to forty minutes. In addition, it is always a short-distance car to hurt the car, the car is moving at any time but not far away, is an important reason for injury.
