车辆保养是每个车主都需要了解的重要内容，随着车辆行驶里程数的不断增加，零部件的使用情况也会有明显不同，所以对其维修保养作业的深度和广度，也会有相应的侧。据此，业内普遍将车辆保养划分为三个级别，即一级保养、二级保养、三级保养，今天就让我们就来了解一下吧。

　　Vehicle maintenance is an important aspect that every car owner needs to understand. As the mileage of the vehicle increases, the usage of its components will also vary significantly. Therefore, there will be corresponding emphasis on the depth and breadth of its maintenance operations. Based on this, the industry generally divides vehicle maintenance into three levels: first level maintenance, second level maintenance, and third level maintenance. Today, let's take a look.

　　一级保养

　　First level maintenance

　　一般车辆行驶1500-2000km时，采用的是一级保养，此阶段的保养工作以紧固、润滑和清洁为主。

　　When a typical vehicle travels 1500-2000km, it adopts first level maintenance, which mainly involves tightening, lubrication, and cleaning.

　　在一级保养阶段强调润滑和紧固的重要性，是因为新车在使用初期，各个运行部件仍处于磨合阶段，特别是发动机运动件，在高速运转过程中很容易产生金属碎屑，这些碎屑掉落到机油中，将会加剧运动件的磨损。除此之外，各运动件在高速运转时产生的高温会使润滑剂挥发，一旦润滑剂量少形成干摩擦后，运动件的磨损就会加剧，所以此阶段必须注意定期添加润滑剂。

　　Emphasizing the importance of lubrication and fastening during the first level maintenance stage is because in the early stages of new car use, various running parts are still in the running in stage, especially the engine moving parts, which are prone to produce metal debris during high-speed operation. These debris will fall into the engine oil and exacerbate the wear of the moving parts. In addition, the high temperature generated by the high-speed operation of various moving parts will cause the lubricant to evaporate. Once the amount of lubricant is reduced and dry friction is formed, the wear of the moving parts will intensify. Therefore, it is necessary to pay attention to regularly adding lubricant at this stage.

　　一级保养的内容有：

　　The key contents of first level maintenance include:

　　将汽车冲洗干净，包括发动机和底盘的油垢以及污泥都要清洗干净。

　　Wash the car thoroughly, including cleaning the engine and chassis of oil stains and sludge.

　　更换发动机机油，各滤清器中的沉积物，并排除储气筒内的油污。

　　Replace the engine oil, remove sediment from each filter, and remove oil stains from the air reservoir.

　　检查发动机油盘、变速器、后桥、转向机的润滑油量是否在标准部位以上，如油量偏低，需添加润滑油标准部位。此外也要润滑汽车分电器、转向拉杆球头销、离合器踏板支架销、转动轴、前后钢板弹簧销及车门等部位（可参考各车使用说明书规定的润滑点进行润滑）。

　　Check whether the lubricating oil level of the engine oil pan, transmission, rear axle, and steering gear is above the standard position. If the oil level is too low, add lubricating oil to the standard position. In addition, it is necessary to lubricate the car distributor, steering rod ball joint pin, clutch pedal bracket pin, rotating shaft, front and rear steel plate spring pins, and doors (refer to the lubrication points specified in the user manual of each vehicle for lubrication).

　　检查备胎升降器及备胎的固定情况，润滑备胎升降器各部位。

　　Check the fixing condition of the spare tire lifter and spare tire, and lubricate all parts of the spare tire lifter.

　　检查并紧固发动机、变速器、传动轴、主减速器、底盘、车身外部的连接螺栓与螺母，如有缺失，应按规定的规格和数量配备齐全。

　　Check and tighten the connecting bolts and nuts of the engine, transmission, drive shaft, main reducer, chassis, and exterior of the vehicle. If there are any missing bolts, they should be fully equipped according to the specified specifications and quantities.

　　检查并调整空气压缩机、发电机等各传动带的松紧度。

　　Check and adjust the tightness of various drive belts such as the air compressor and generator.

　　检测电器设备，包括仪表、灯光、空调和暖气装置的功能看其是否工作正常。

　　Check the functionality of electrical equipment, including instruments, lighting, air conditioning, and heating devices, to see if they are working properly.

　　检查蓄电池液面高度是否符合规定高出极板10~15mm，其外壳是否有渗漏现象。

　　Check if the battery liquid level is 10-15mm above the electrode plate according to regulations, and if there is any leakage in its casing.

　　二级保养

　　Secondary maintenance

　　二级保养多数是在车辆行驶6000~8000km时进行的，此阶段以深入检查和调整为主，其目的是为了保持车辆在以后较长时间内，能保持良好的性能。

　　The second level maintenance is mostly carried out when the vehicle has been driven for 6000-8000km. This stage mainly focuses on in-depth inspection and adjustment, with the aim of maintaining good performance of the vehicle for a long time in the future.

　　二级保养除执行一级维护作业外，还需要更换各类滤清器，检查和调整发动机、制动系统和电器设备，同时进行轮胎换位等。这部分工作比较，一般都由维修工进行。

　　In addition to performing first level maintenance tasks, second level maintenance also requires replacing various filters, inspecting and adjusting the engine, braking system, and electrical equipment, as well as changing the tires. This part of the work is relatively professional and usually carried out by professional maintenance workers.

　　在一级保养的作业内容外，二级保养范围有所增加，如：

　　In addition to the scope of first level maintenance, the scope of second level maintenance has been expanded, such as:

　　对发动机的各项性能进行检测，从而确定需要检修和调整的项目。有条件时应采用免拆卸清洗仪清洗发动机的油路，积碳、油脂和结胶。

　　Conduct a comprehensive inspection of the engine's various performance indicators to determine the items that require maintenance and adjustment. When conditions permit, a non disassembly cleaning device should be used to clean the engine's oil circuit, remove carbon deposits, grease, and adhesive buildup.

　　清洗化油器、燃油泵，必要时在试验台上调校。

　　Clean the carburetor and fuel pump, and adjust them on the test bench if necessary.

　　检查底盘上各个总成，各运动部件有无磨损，更换已磨损的零件。

　　Check all assemblies and moving parts on the chassis for wear, and replace worn parts.

　　检查轮胎气压和磨损情况，并按规定进行4轮定位。

　　Check the tire pressure and wear condition, and perform 4-wheel alignment according to regulations.

　　检查驾驶室、门窗、座椅、门锁、玻璃升降器以及各种开关是否完好。

　　Check if the driver's cab, doors and windows, seats, door locks, window regulators, and various switches are intact.

　　三级保养

　　maintenance at three levels

　　当汽车行驶了36000~40000km左右时，为了巩固和保持各个总成、组合件的使用性能，需要对汽车进行三级保养。

　　When the car has traveled about 36000~40000 km, in order to consolidate and maintain the performance of various assemblies and components, it is necessary to perform level three maintenance on the car.

　　三级保养在一、二级保养的基础上，增加了对发动机、变速器、前桥、后桥、传动轴、制动器等总成进行解体、清洗、检查、调整和隐患的工作，必要时也可对车身进行除锈和补漆。

　　On the basis of the first and second level maintenance, the third level maintenance adds the work of disassembling, cleaning, inspecting, adjusting, and removing hidden dangers of the engine, transmission, front axle, rear axle, transmission shaft, brake and other assemblies. If necessary, the vehicle body can also be rust removed and repainted.

　　由于车辆行驶里程数较多，此时车辆零件已不如从前，所以三级保养的工作难度要远远大于其他两级的工作难度。

　　Due to the high mileage of the vehicle, the parts of the vehicle are not as good as before, so the difficulty of level three maintenance work is much greater than that of the other two levels.

　　三级保养在一、二级保养的基础上，添加了以下内容：

　　The third level maintenance adds the following content on the basis of the first and second level maintenance:

　　拆检发动机，检查气缸、活塞、活塞环及拉杆、轴承磨损情况，积碳、结胶及冷却系水垢，研磨气门及调整间隙。

　　Disassemble and inspect the engine, check the wear of cylinders, pistons, piston rings, rods, and bearings, remove carbon deposits, adhesive deposits, and cooling system scale, grind valves, and adjust clearances.

　　对前桥、转向、变速器、传动轴、后桥、悬挂和制动器等总成应进行解体、清洗、检查、调整、故障排除等工作。

　　Disassemble, clean, inspect, adjust, and troubleshoot the front axle, steering, transmission, driveshaft, rear axle, suspension, and brake assemblies.

　　检查空气压缩机、散热器、水泵的固定情况及其管道，看是否有漏油、漏气现象，并排除储气筒内的油水及污物。

　　Check the fixing condition and pipelines of the air compressor, radiator, and water pump to see if there is any oil or gas leakage, and eliminate the oil, water, and dirt in the air storage cylinder.

　　检查百叶窗的工作性能及水泵轴的润滑情况。

　　Check the working performance of the blinds and the lubrication of the water pump shaft.

　　检查前轴(工字梁)有无弯曲、断裂现象，并对前束进行检查和调整。

　　Check the front axle (I-beam) for any bending or breakage, and inspect and adjust the front beam.

　　检查喇叭、指示灯、制动灯、转向灯、大灯等的照明设备，以及电器仪表的工作状况。

　　Check the working condition of lighting equipment such as horns, indicator lights, brake lights, turn signals, headlights, and electrical instruments.

　　检查车架有无裂缝、铆钉有无松动。

　　Check for cracks in the frame and loose rivets.

　　无论是一级保养、二级保养还是三级保养，都需要人员对车辆进行检查，而对车辆零部件了解的一定是原厂，所以给爱车进行原厂保养，会让其得到更合理的养护，然而可惜的是，市面上的二手车基本没有原厂保养服务。              车辆保养是每个车主都需要了解的重要内容，随着车辆行驶里程数的不断增加，零部件的使用情况也会有明显不同，所以对其维修保养作业的深度和广度，也会有相应的侧。据此，业内普遍将车辆保养划分为三个级别，即一级保养、二级保养、三级保养，今天就让我们就来了解一下吧。

　　Whether it is first level maintenance, second level maintenance, or third level maintenance, professional personnel need to conduct a comprehensive inspection of the vehicle, and the ones who know the most about vehicle components are definitely the original factory. Therefore, providing original factory maintenance for your beloved car will enable it to receive more comprehensive and reasonable maintenance. Unfortunately, there is basically no original factory maintenance service for used cars on the market. Vehicle maintenance is an important aspect that every car owner needs to understand. As the mileage of the vehicle increases, the usage of its components will also vary significantly.
