Summer is coming, do you know that summer cars also need sunscreen? What do you know about summer car sunscreen common sense? Today, I will tell you some common sense of summer car sunscreen, which can effectively prevent your car from heat stroke.
Protect the paint surface – Sun exposure can do a lot of damage to car paint. For car owners who take care of their car’s “face”, be sure to wash the car frequently and wax it regularly. If you want to do the protection work more thoroughly, it is recommended to make a paint surface sealing glaze or coating, and put a layer of “crystal protective clothing” on the car paint.
Pay attention to cleanliness – in the summer when you love driving windows, dust is easy to blow into the car, and after a period of time, the car will become sticky and dirty, and even smell. The instrument panel, door trim panel and other plastic parts should be cleaned with a brush and detergent. In order to prevent cracks and aging caused by ultraviolet radiation, a layer of surface wax can be applied after cleaning.
Prevention of puncture – the road surface temperature is higher in summer, and the use environment of automobile tires is even harsher. Therefore, we must pay attention to the inspection and maintenance of automobile tires, and regularly check the tire pressure to prevent tire punctures.
Check the brakes – the wet road in the rainy season reduces the friction coefficient between the tire and the road, especially when there is water on the tire tread, the friction coefficient is lower, and a sensitive braking system is particularly It’s important, so check your brakes from time to time and try to be prepared.
Prevention is not “burning” – summer is a period of high incidence of spontaneous combustion of vehicles. It is understood that improper operation of drivers or hidden dangers of vehicles are the main reasons for spontaneous combustion of vehicles. Therefore, it is necessary to focus on checking the oil and electricity lines of the car. If the lines are found to be aging, they should be repaired in time to prevent spontaneous combustion.
Use the air conditioner skillfully – open the windows for ventilation before entering the car, and open the external circulation at the same time, and then turn on the air conditioner after the hot air in the car is exhausted, so that the cooling effect is faster and better. When the vehicle speed is lower than about 25km/h, the air conditioner should be placed in a lower gear to prevent insufficient power generation and air conditioning. When driving in rainy days, the window glass is easy to fog up, which affects the vision. At this time, as long as the wind direction is adjusted to the windshield direction, and the compressor is turned on to send air-conditioning, the purpose of effective defogging can be achieved within a few seconds.
Prevent evaporation – the temperature is higher in summer, and the evaporation of oil and water will increase, so be sure to cover the fuel tank tightly, and the oil pipe to prevent oil leakage; check the water level of the water tank frequently and the oil in the crankcase Oil level, height, brake fluid level in brake master cylinder and electrolyte density and fluid level in battery. When it is not in compliance with the regulations, it should be added and adjusted in time.
Pay attention to “antifreeze” – in summer, some people think that antifreeze is not available and can be replaced with ordinary tap water. In fact, this practice is not appropriate. The professionally formulated antifreeze is not only resistant to low temperature, but also has excellent high temperature resistance. High-quality antifreeze can only be “boiled” when it is close to 200 ??C. When antifreeze is used in summer, car owners are not easily troubled by the “boiling” of the water tank. In addition, antifreeze also has anti-rust and descaling effects. Therefore, it is still necessary to use the original antifreeze in summer, which can play the role of “heatstroke prevention and cooling”.
Air conditioning and refrigeration system – Air conditioning is a very frequently used component in summer, and it is also the most prone to failure. The most common failures of automotive air conditioning systems are refrigerant leakage and poor cooling. Refrigerant leakage is usually caused by aging of the sealing rubber ring in the pipeline, abnormal refrigerant pressure, and damage to system components. After the leakage fault is repaired, the refrigeration oil must be replenished, the system must be evacuated and the refrigerant must be filled. The refrigeration oil and refrigerant must be of good quality and the same model as the vehicle required. Among the many failures of poor refrigeration, the most common is the poor heat dissipation of the air conditioning system. The items that need maintenance are mainly the cleaning of the condenser and the working condition of the cooling fan.
