Many private car owners like to wash their cars under the scorching sun, believing that the water on the body can be dried soon after washing. In fact, it is wrong. When washing the car under the scorching sun, the convex lens effect formed by the water droplets will cause the uppermost layer of the car paint to produce a local high temperature phenomenon. Over time, the car paint will lose its luster. If waxing at this time, it is also easy to cause uneven color of the car body. Therefore, it is best to wash and wax the car under sheltered conditions. If it is not guaranteed, it is best to choose it in the morning and evening on a cloudy or sunny day. The owner should understand the following correct maintenance knowledge.
Washing the car is like taking a bath-harmful to the air conditioner

Waxing in a circle-poor effect
Many people habitually wax the car body in a circle, which is not the correct method. The correct way of waxing is in a straight line, alternating horizontal and vertical lines, and then the last one in the direction of rainwater flow, so as to reduce the effect of concentric circles on the paint surface.
Too much oil-malfunction
When the oil in the engine oil pan is insufficient, the friction between the bearing and the journal will cause poor lubrication due to the small amount of oil, aggravate the degree of wear, and even cause a bush-burning shaft acciden

Too much oil-malfunction
When the oil in the engine oil pan is insufficient, the friction between the bearing and the journal will cause poor lubrication due to the small amount of oil, aggravate the degree of wear, and even cause a bush-burning shaft accident.However, if the engine oil is too much, the engine is workingCrankshaftThe handle and the big end of the connecting rod will produce violent agitation, which not only increases the internal power loss of the engine, but also increases the oil splashing on the cylinder wall, causing the failure of burning and draining the oil. Therefore, the oil in the engine oil pan should be controlled between the upper and lower engraved lines on the oil dipstick.
Bolt is too tight-permanent deformation
beltThe tightness of the engine can improve the cooling effect of the engine, so it keeps improvingfanThe tightness of the belt causes the fan belt to be too tight, but it is not true that this approach is wrong.The fan belt should be kept tight properly, because too tight will cause excessive load on the bearing, aggravated wear, and increased power consumption.Water pumpThe shaft is bent, the belt is elongated and deformed, and its life is shortened.
importtire--not applicable
Some people buytireI especially like to emphasize "import". The most fatal flaw of the new tires introduced abroad for domestic users is that they are not applicable. The flat roads in Europe are quite different from the road conditions of the second and third ring roads in Beijing. The tires suitable for European road conditions will not perform well in Beijing, especially the impact resistance of the sidewalls is obviously not suitable for water and soil, just like wearing Italy Brand-name leather shoes are generally gravel, and the sidewalls are inevitable. After some foreign brand tires are produced by domestic joint ventures, a layer of cord fabric is added to the side of the tires according to the domestic road conditions, which greatly enhances the impact resistance of the sidewalls. The joint venture tires can completely replace imported goods in terms of performance. .
newAccumulatorNo charge-shorten life
The first charge of the battery is called the first charge, and the first charge has a great influence on the service life of the battery. If it is not charged, that is, if it is used directly with "water", the capacity of the battery is not high and its life will be shortened; if it is directly charged, it will also shorten its life. Generally, the initial charging of the battery is after filling the electrolyte, and then it can be installed and used after charging with a small current for about 1 hour.
In-car equipment is added at will-affect driving safety
Private cars are homes for car owners to move. There is nothing wrong with pursuing passenger comfort and luxury. However, some car owners install various equipment in the car by themselves. If this modification is not handled properly, it will often affect the performance and convenience and reliability of the car. Bring adverse effects, easily leave sequelae or affect driving safety.
