What if the temperature exceeds 30℃?

In hot summer, high temperature will not only make people uncomfortable, but also damage our cars. In addition, the rainy days in summer make cars more vulnerable, so how should we maintain our cars in summer? Today, Bian Xiao will talk to you about how to maintain cars in summer.

Pay attention to the air conditioner, compressor and condenser of the car.

It's very hot outside in summer, and the heat inside the car is unbearable. Many car owners turn on the air conditioner when driving, and the air conditioner is always on. How to maintain it to prolong its service life? First of all, don't turn on the air conditioner immediately when the car starts. You have to open the window for 3-5 minutes, and then turn on the air conditioner when the hot air in the car runs out. The effect is better at this time. In addition, the air conditioner of the car should not be turned on for a long time, so as not to overload the engine for a long time. In addition, the air outlet of the air conditioner should be kept up, because the cold air will sink. In hot summer, always maintain the compressor and condenser of the car. The owner should regularly check the belt tension of the compressor. If there is any leakage of refrigeration oil, it should be handled in time. We should always clean the condenser to prevent oil, dust and debris from sticking to the radiator of the condenser. In addition, we should ensure that the compressor works every two weeks 10 minutes or more.

Tire pressure and wiper blade

According to the physical characteristics of thermal expansion and contraction, hot summer weather will lead to the increase of air pressure in tires with the increase of temperature, which will easily lead to tire puncture accidents. At the same time, it is easy to cause overspeed, overload or emergency braking and puncture during driving. Therefore, check the tires frequently in summer. If the tire pattern is flat, you need to replace it with a new one. At the same time, you should reduce the tire pressure or fill helium, which is more stable and not easy to expand. There are many rainy days in summer. Car wipers are used frequently, so we need to maintain the frequently used parts. In addition to regularly checking whether the wiper blade is in good condition, it is also necessary to clean the wiper blade frequently to prevent dust and magazines on the wiper blade.

It will affect the wiping effect and damage the front glass. Once the glass is scratched, it will be very troublesome, so the owner must not be lazy.

Body care and disinfection in the car

It often rains in summer, and the acidic substances in the rain will cause the corrosion of the car body. In summer, glue and other impurities on the car body may lead to corrosion and acidification of the paint. Therefore, it is necessary to wash the car frequently, from cleaning, polishing, waxing, sealing to maintaining the car body. Even if the body has been painted, everything is not good. You must wash the car often. At the turn of spring and summer, cars should be disinfected. Besides often opening windows for ventilation, washing cars regularly and cleaning the interior decoration, disinfectants should be used more. If conditions permit, you can go to a professional store for high-temperature disinfection with ultraviolet rays. It should be noted that during automobile disinfection,

Leave unattended, ventilate for 5-6 minutes after disinfection, and then clean the car with water.

Gasoline and lubricating oil

Many car owners don't pay attention to choosing the right gasoline label, and some even choose some gasoline with reduced standard in order to save money, which is actually not desirable. No matter whether the gasoline exceeds the standard or does not meet the standard, there may be no difference in the short term, but long-term use will shorten the service life of the car, especially in summer. When the temperature exceeds 30℃, this gasoline will accelerate the damage of the car, so we must pay attention to avoid this situation as much as possible in summer. Automobile lubricating oil is very important for automobile, but in summer, because the engine works in high temperature environment for a long time, it will transfer heat to the lubricating oil, which will lead to oxidation and deterioration of the lubricating oil and affect its function. Long-term use of inferior lubricating oil or deterioration of lubricating oil will lead to gelation of oil circuit and cause oil alarm. In the worst case, serious accidents such as cylinder pulling, bushing burning and shaft setting will occur. Therefore, car owners should pay special attention to lubricating oil in summer, and replace it with a new one in time when it is found to be deteriorated.

In summer, many people will use water instead of antifreeze, but this idea is too simple. Good antifreeze not only has the function of cooling the engine, but also has good low-temperature and high-temperature tolerance, and even has the functions of corrosion protection and rust removal. So it is not recommended to use water instead of antifreeze. Water will slightly corrode the cooling system, and antifreeze contains anti-corrosion and anti-rust additives. Secondly, the boiling point of antifreeze is higher than 120 degrees Celsius, while the boiling point of water is only 120 degrees Celsius.
