FAW Bestune has been in our lives for more than two years. With the continuous growth of sales volume, it has formed a considerable team of car owners. In order to enrich car owners' knowledge of vehicle use and maintenance, more than 60 dealers of FAW Bestune across the country jointly opened the "Car Owners Lecture Hall", which mainly focused on the use of vehicles, vehicle maintenance, vehicle maintenance and other aspects.
With the advent of summer and the increase in temperature, the "heatstroke prevention" of vehicles has also become a major focus. In this regard, experts from FAW Bestune introduced the following key issues in the "Car Owners Lecture Hall":
cleanWater tankwithCondensersurface
In order to ensure the working effect of the air conditioner, car owners should pay special attention to cleaning the water tank,Condensersurface. After a few months of winter and spring,carThe surface of the water tank and condenser will be covered with a lot of dust and catkin-like debris, which will cause problems such as high water temperature and poor cooling effect of the air conditioner, which will cause the air conditioner electronic fan to work for a long time, easily damage the air conditioner, and increase vehicle fuel consumption. At the same time, vehicle owners may also find that the noise of the vehicle increases.
Clean the air duct and evaporator of the air conditioner
The dust in the north is very large in spring. Dust and impurities will generally accumulate on the surface of the air-conditioning duct and evaporator. After a long time, mildew will occur. When the weather becomes warmer, a large number of bacteria will breed. At this time, the car owner will find that there is The appearance of peculiar smell affects the health of people in the car.Therefore, b

lubricating oilTo be replaced on time and quarterly
The lubricating oil will lose its lubrication protection after being used for a period of time due to oxidation, pollution and quality degradation. It is very necessary to change the lubricating oil on time and quarterly. Under normal circumstances, car owners in most parts of the country from April to September can choose summer lubricants No. 20w-40 or No. 10w-40. When choosing the viscosity grade of the lubricating oil, the load of the engine must also be considered.Rotating speedAnd wear. If the engine load is large, the speed is low, or the wear is severe, the lubricating oil with higher viscosity should be selected, otherwise, the lubricating oil with lower viscosity should be selected.
When checking the amount of lubricating oil, pay attention to the amount of lubricating oil consumed after the engine runs for a period of time. Add lubricating oil according to the actual situation.Remember: add lubricating oil should not exceed the mark on the line, otherwise it will increase due to too much lubricating oilCrankshaftThe rotation resistance reduces the output power of the engine.And if there is too much lubricating oil, the engine will burn lubricating oil and emit blue smoke, which will increase fuel consumption and accelerate thepistonThe wear and tear shortens the service life of the engine.
Timely adjustmenttireExplosion-proof tire
Car owners should check frequently in summertire, So as to avoid the occurrence of puncture and other situations. Tire pressure is very important for driving safety. After the weather gets warmer, the tire pressure changes with the ambient temperature. Generally, for every 10°C increase in temperature, the tire pressure will increase by about 7 to 14kpa. In the scorching summer, the tire is in contact with the hot ground. If the tire pressure is high, it is likely to cause a puncture. So don't let the tire pressure be too high when driving in high temperature, and the speed should not be too fast.
In addition, pay attention to the instructions of the various instruments of the vehicle when driving. In summer, pay special attention to the instructions of the water temperature meter: generally, it should not exceed 95°C. When the water temperature exceeds 100°C, stop and check immediately. If the engine temperature is too high, the expansion of the parts will reduce the matching clearance of each part. On the other hand, the viscosity of the oil will decrease when the temperature is too high. In this case, the wear of each part will increase and the life of the engine will be reduced.
What should I do if the water temperature is too high, even "boiling"? Quickly find a cool place to stop and cool down, let the engine run at idle speed, and open the hood to speed up heat dissipation. When the temperature drops, add enough water to the water tank. There are three taboos to cool down the car after boiling:
Don't turn off the fire immediately after boiling: Some drivers think of turning off the fire immediately when they notice that the pan is boiling. You know: The reason why the engine is boiling is because the temperature of the water in the water jacket is too high, that is, the temperature of the cylinder liner, cylinder wall, and cylinder head is too high. If the flame is turned off at this time, the parts are in an expanded state, and the matching clearance is very small. After the shutdown, some soft metals will fall off, and some may even cause the cylinder to stick. So after discovering that the pot is boiling, do not turn off the fire immediately, and keep idling. If the flame has been turned off, the car should be cranked immediately to prevent sticking to the cylinder.
Second, avoid opening the lid and adding water immediately when boiling: After the water in the water tank boils, there is a certain pressure inside. If you open the lid of the water tank immediately, hot water will spray out, which can easily cause burns.
Three refrains from pouring cold water on the engine when the engine temperature is too high: Some people find that they are boiling and pour cold water on the engine block and cylinder head to cool down. Little do they know that such consequences are serious, and may cause the engine block to burst due to sudden cold, resulting in irreparable consequences.
These basic knowledge of summer driving, hope to bring more practical help to the car owners based on popularizing the knowledge of car use, and I also recommend that you continue to pay attention to the caring service information delivered from the Besturn "Car Owner's Lecture Hall".
