01
Keep car air conditioning dry
When the weather temperature rises and dust increases, the car body is prone to getting dirty, and the frequency of car washing by car owners will also increase. Many car owners even wash their cars thoroughly, just like taking a shower.
But it should be noted that when washing the car, it is important to keep the exterior of the car air conditioner dry. If the car air conditioner is accidentally wet, it may affect its lifespan.
02
Don't wash too frequently
On normal sunny days, if it is not very dirty, you can wash it once a week. If you wash it once every 1-2 days, the lifespan of your car paint will be greatly reduced; But when it rains or snows, it is also important to wash the car in a timely manner to prevent corrosion.
03
Do not tighten the bolts too tightly
There are many fasteners connected with bolts and nuts in cars, and they should be ensured to have sufficient pre tightening force, but they should not be tightened too tightly. If tightened too tightly, on the one hand, it will cause permanent deformation of the connector under external force; On the other hand, it will cause permanent tensile deformation of the bolt, and even cause slipping or breakage.
04
Do not tighten the fan belt too tightly
When the temperature is too high, some drivers believe that increasing the tightness of the fan belt can improve the engine cooling effect, so they keep increasing the tightness of the fan belt, but little do they know that doing so is harmful. The fan belt should be kept appropriately loose, as being too tight can cause excessive bearing load, increase power consumption, and also bend the water pump shaft, elongate and deform the belt, and shorten its lifespan.
05
Be cautious when using imported tires
Some people like to emphasize "imports" when buying tires. In fact, new tires from abroad are not very suitable for domestic users.
After some foreign brand tires are produced through joint ventures in China, a layer of curtain fabric is added to the side of the tires according to the domestic road conditions, greatly enhancing the impact resistance of the sidewalls. Joint venture tires can completely replace imported goods in terms of performance.
06
Car wash flow
From the appearance, washing a car is just a simple physical labor, seemingly without any skills, but the water flow of washing a car is very particular. A more professional car wash shop will never use a high-pressure water gun to spray wildly at the beginning. Generally, the first time it is necessary to use fine water to flow slowly, from top to bottom, and take away the dust particles on the car with water flow. If a high-pressure water gun is used from the beginning, it is equivalent to causing dust particles to rub against the surface of the car paint.
Sometimes, car owners often wash their cars at roadside shops to save trouble. Those who carry a bucket to wash their cars, if you observe carefully, will find that there is a lot of mud and sand in their bucket, which is no different from using sandpaper to clean the car. Some car wash shops also use towels that have been phased out in hotels. These towels may look new and white, but in reality, they are already very rough and can also harm the car.
07
The waxing effect of the circle method is poor
Many people habitually wax the car body in a circular pattern, which is an incorrect method. The correct waxing method is to use a straight line, alternating between horizontal and vertical lines, and then apply the last layer in the direction of rainwater flow, in order to reduce the formation of concentric circular halos on the surface of the car paint.
