For the car owner who just bought a new car, the common sense about car maintenance is a must. Many friends have asked Xiao Bian what is the car's insurance, second insurance and three guarantees. Today, Beimai.com will give you some general knowledge about car maintenance and how to do the most appropriate introduction to the car insurance. If you do n't understand, please come and see it. Let us first understand what is a guarantee, two guarantees and three guarantees. One insurance is also called the first insurance is free, usually replace the oil and machine filter (some models will also replace the gear oil). The second guarantee is the second maintenance is usually around 1W km. 4S shop usually asks you to do a first-grade maintenance is to replace 4 and oil. Then the front and rear tires are replaced. The third guarantee is the third maintenance. Under normal circumstances, only oil and machine filters need to be replaced. Usually the first insurance is free, the owner should not miss the first insurance, because the new car is in the running-in situation, the mechanical parts run-in, the demand for lubricants will be higher, the significance of doing the first insurance is here. In general, the second guarantee is very important. The project involves the engine detection, the automatic transmission, the cooling system, the steering system, the braking system, the suspension system, the body part, and the tires. Guarantee. In addition to this, it also includes a quality inspection test. Therefore, we must pay attention to the second maintenance of the vehicle. The second guarantee of the vehicle is usually carried out when the new vehicle mileage reaches 10,000 kilometers. In general, after the inspection and maintenance of the second guarantee, the entire vehicle condition will enter the situation significantly, and the safety of driving is guaranteed. After the second guarantee, the function of the new car is basically stable. After that, according to the condition of the car and the application habits, a small maintenance is carried out every 5,000 km-7500 km, and a comprehensive physical examination and maintenance can be done every 10,000-1.5 million km. After the running-in period, it is necessary to pull the high-speed new car to pull the high speed after the running-in period to enhance the function of the engine. After the initial running-in of the new car engine, the middle part of the machine tends to coordinate. At this time, pulling the high speed, let the engine maintain a high speed operation for a period of time, can check the limit working condition of the machine, and expand the bearing range of the tensile, compressive, anti-collision and anti-torsion of the machine data. Especially when working at high temperatures, the strength of metal materials can be greatly improved, and the overall function of the machine can be further enhanced. But to pull the high speed to choose the right time, first of all, it is absolutely impossible to use the box oil to pull the high speed. The metal oil in the box oil is the most, and the impurities are also very much. Using these oils with a lot of debris to pull the high speed will greatly improve The loss of the engine, even causing abnormal losses. Vehicle two insurance inspection and maintenance project: 1. After passing through the three clearing and three filtering operations, the engine should be easy to start, stable in operation, normal in exhaust gas (referring to exhaust gas compliance), water temperature, oil pressure compliance requirements, stable rotation speed, no abnormal noise, moderate tension of each belt, no Four leaks (water, oil, electricity, gas). 2, direction free travel and front beam fit requirements, the steering is light, smart, and reliable, the front wheel has no left and right swing and deviation when driving. 3, the clutch free travel meets the requirements, the operation is convenient, the separation is thorough, the combination is stable, firm, no abnormal sound, the hydraulic system has no oil leakage. 4, gearbox, push bridge, universal joint (or half shaft) transmission equipment and other lubrication, the connection is reliable, no abnormal noise and too hot, no jump gear, smart shift, no oil leakage. 5. Brake pedal free travel and brake intermittent fit requirements, driving, parking brake is good, no deviation during braking and drag when braking, inertial proportional valve works normally, does not leak oil. 6, the tire pressure is normal (different models require high pressure standards are not the same). 7. The cantilever and shock absorber are firmly fixed and the performance is normal. The temperature of the hub bearing is lower after driving. 8, generators, fans, lights, meters, signal lights, buttons, switches are fully equipped, complete, and can work normally. 9.
