Necessity of maintenance
1. Car maintenance can ensure that the vehicle is in excellent performance and ready to go, without worrying about the technical condition of the vehicle.
2. It can effectively improve the efficiency of vehicles and reduce the fuel consumption and the consumption of spare parts and tires. For example, the engine, regular maintenance will not increase its fuel consumption, but will be easier.
3. Increase driving safety. The function of maintenance is to avoid unexpected problems during driving and ensure personal safety.
4. Avoid the danger of continuous minor faults of vehicles. Maintenance can improve the performance of vehicles, and minor faults can be found and handled in time.
5. Noise and environmental pollution can be reduced. After automobile maintenance, the tail gas is maintained to effectively deal with its pollutant discharge.
6. Keep the vehicle clean and tidy, prevent undue damage, actively investigate hidden dangers and eliminate them in time.
1, the use of air conditioning
First, turn on the external circulation of the air conditioner. The temperature inside the car is often very high in summer. So, don't turn on the air conditioner immediately when the car starts. Open all the windows for 3-5 minutes, and then turn on the air conditioner after the hot air is exhausted. This will have a better effect. If the engine is under heavy load for a long time, the air conditioner should be temporarily turned off. When cooling, it is best to blow the wind direction of the air conditioner upward, because the cold air will sink downward. It is best to choose the wind direction to blow on the face and adjust the air outlet upward for the best effect. Finally, pay attention to turn off the air conditioner before the destination to reduce the odor.
2. Compressor and condenser
After the refrigeration system stops, the compressor should run every two weeks 10 minutes or more. Check the belt tension of the compressor regularly. The radiator is connected to the condenser.
3. Tire pressure
Tires must be checked. If the pattern is worn, new tires must be replaced. In summer, the air pressure in the tire will increase with the increase of temperature, which often leads to puncture accidents. At the same time, speeding, overloading or emergency braking are also easy to cause tire puncture. Therefore, the tire pressure can be appropriately reduced, or helium gas with more stable physical properties and less expansion can be filled into the tire.
4. Wiper blade
Because there is more rain in summer, the frequency of use of automobile wiper blades will be higher, so it is particularly important to strengthen the inspection of wiper blades. In addition to regular inspection, it is also necessary to pay attention to the cleaning of the wiper to prevent the accumulation of dust and impurities on the wiper from affecting the wiping effect, or negatively affecting the front glass, scratching and so on. Very troublesome. Once the wiper blade does not work well, it must be repaired and replaced in time, so don't lose too much because of small.
5. Body care
There is more rain in summer and autumn, and the acidity in the rain, coupled with strong sunlight, will cause corrosion and oxidation to the paint surface. After a long period of wind, rain and sun exposure, your car's face must be painful and gaunt. Therefore, a series of beauty maintenance should be carried out from the aspects of cleaning, polishing, waxing and glaze sealing. Even if your body has been painted, you should take good care of it and clean it happily.
6, disinfection in the car
Spring is in full swing, so it is very important to do a good job of disinfection in the car. Always open the window for ventilation and clean the inside and outside of the car regularly. You can scrub yourself with disinfectant when cleaning. If you have time, you can also go to a special repair shop for ultraviolet irradiation or high temperature disinfection. However, it must be noted that the air disinfection in the carriage is carried out when there is no one in the car. After disinfection, open the window for ventilation for 5-6 minutes, wipe the facilities in the carriage with clean water, and then dry them with clean cotton cloth to remove the residual disinfectant.
