The car water tank, also known as the radiator, is the main part of the car cooling system; its function is to dissipate heat. The cooling water absorbs heat in the water jacket, flows to the radiator and dissipates the heat, and then returns to the water jacket for circulation. achieve the purpose of adjusting the temperature. If the water temperature is too high, where should we find the cause? First of all, there may be a problem with the fan of the water tank. The function of the fan is to accelerate the air flow, take away the heat on the water tank, and achieve better heat dissipation. If the fan does not work, the cooling effect is weakened, and it is easy for the water temperature to be too high. The second problem may be the car coolant. The coolant circulates in the cooling system, which can take...

About the oil change. People who don't understand cars don't know the oil change cycle. How to change the oil? If the owner remembers these 3 standards, he can change the oil by himself. 1: Expiration date. Oil is a consumable, and the longer it is used, the worse the effect will be.

There are many safety hazards in the process of using the car, especially the following three situations, which must be paid special attention! First: Do not over-inflate the tiresBecause the sun is in direct sunlight for a long time , the surface temperature can reach seventy or eighty degrees, the air pressure in the tire increases, the tire becomes soft, and it is easy to blow the tire, so the tire pressure should be checked regularly. Second: Do not put explosives in the carIn summer The temperature can reach 60 degrees. If lighters, high-pressure fragrances and easy-to-melt items are exposed to a high temperature environment for a long time, a high temperature explosion will occur, which is quite dangerous.

It's almost summer, and it's hot. When the weather is hot, you need to turn on the air conditioner when driving. Many car owners will struggle with the fuel consumption problem after turning on the air conditioner. After all, they spend their own money. So does the air conditioner in the car consume a lot of fuel? Does the lower the temperature, the higher the fuel consumption? The fuel consumption of the car with refrigeration and air conditioning is certain. It's just that it's very fuel-efficient, not necessarily. Because the air conditioning of the vehicle requires the compressor to work, and the work of all the equipment systems of the vehicle will increase the fuel consumption, not to mention that the air conditioning compressor is not a small piece of equipment. In general, the fuel consumption of the vehicle will increase by about 10% if the refrigeration and air conditioning...

Master the charging timeDifferent from refueling fuel vehicles, electric vehicle charging requires the owner to accurately grasp the time. If you choose a home charging pile to charge, it will take about 8 hours to fully charge, and even Tesla's fast charge will take nearly an hour. As a new energy vehicle owner, since choosing an electric vehicle, we must accept his characteristics. It is true that pure electric vehicles are much more troublesome than gasoline vehicles. Second, it is not advisable to overcharge and dischargeThe battery of an electric vehicle, like that of a mobile phone, should not be overcharged and discharged.
