Prevent "boiling" once it is overheated, stop first
In the sweltering summer, the engine malfunctions due to its own overheating is also increasing. Sometimes when I drove on the road, I found that there was a lot of heat under the car cover, so I stopped and opened the car cover to take a look.Water tankThe water inside has been "boiled" and splashed out from time to time. This is commonly known as "boiling".causecarThere are many reasons for boiling. High temperature weather, overloaded operation of air conditioners, and failure of heat dissipation elements will inevitably affect the heat dissipation of the engine. In addition, when driving in urban areas, frequent starting and stopping will aggravate the friction of engine components and cause the temperature to rise. Especially the long-term operation of the air conditioner discharges a large amount of heat, which deteriorates the heat dissipation condition of the heat dissipation system.fan,heat sinkFailure of other components will also affect the heat dissipation of the engine, which will cause the water temperature of the water tank to rise sharply in a short period of time.
When the water tank is "boiling", do not turn off the fire and add water immediately. Be sure to stop for maintenance and stop driving, otherwise serious problems such as cylinder explosion may occur.
Solution: Stop immediately and let the engine keep idling to continue to dissipate heat; open the hood to increase the heat dissipation speed. After the cooling water temperature is lowered, turn off the engine. At this time, if the amount of cooling water is insufficient, it should be added slowly to prevent the cylinder head from cracking due to sudden cold.
In summer, the coolant evaporates quickly. Check whether the coolant is missing frequently. If it is missing, replenish the same

In summer, the coolant evaporates quickly. Check whether the coolant is missing frequently. If it is missing, replenish the same brand in time.antifreeze, Do not add other brands of antifreeze or water.Because antifreeze is a car enginecooling systemThe main working medium inside, its main function is to make the engine cooling system through forced circulation, so that the engine maintains a proper working temperature.
Antifreeze formulated with ethylene glycol and other chemical components is not only resistant to low temperatures, but also has excellent high temperature resistance characteristics. This kind of antifreeze can only be "boiled" when it is close to 200°C. Fill the water tank with this kind of antifreeze in summer, and you will not be troubled by the "boiling" of the car water tank. In addition, the antifreeze also has the function of preventing rust and descaling.
Explosion-proof tire tireRemember to check frequently
Summer is the season when tires are more likely to blow out, and the hot weather is easy to maketireDeformation, the tensile strength drops. As for the tire itself, non-standard air pressure, aging of the tire, weakened performance, or the tire rolling onto a hard metal or other hard objects during driving, will cause the car to suddenly burst. Always check the temperature and air pressure of the tire when driving under high temperature conditions to ensure the tire pressure standard. If the air pressure is found to be too high or insufficient, it should be adjusted in time. If you find that the temperature of the car tire is too high, remember not to use the method of pouring cold water to lower the temperature of the tire. This will cause cracks due to uneven shrinkage of the tread and sidewall rubber layer.
Solution: Clean up the debris in the fetus in time. When the vehicle is running, some debris, such as nails, stones, glass, iron pieces, etc., will be embedded on the surface of the tire. If it is not cleaned up in time, the debris will be inserted into the tire body step by step, causing the cord strength to decrease, causing delamination or even delamination. A puncture. When it is very hot in the midday, the speed of the car should be reduced appropriately.
