What is the standard for the first level of maintenance of the vehicle?

The standard for the first level of maintenance of the car. In addition to changing the oil and water, it is necessary to check other parts of the vehicle. in the vehicle. There are maintenance and repairs. You can take a look at the maintenance manual of the car.

The regular maintenance of the vehicle belongs to the first level of maintenance.

The main content of the first level of maintenance is to focus on lubrication and tightening, require the oil of the engine to be changed, and systematically check the amount of lubricating oil in each assembly. When the car reaches the specified interval mileage (generally 1500 to 2000 kilometers), the maintenance worker cooperates with the driver. Level 1 maintenance was actually later included in the category of "first maintenance".

In the first level of maintenance, the focus of the inspection is on the oil level of the engine, transmission, braking system, power steering system and differential, as well as the level of the cooling system, cleaning system and battery. Grease should be added to the moving nodes according to the regulations (there are generally grease nozzles in these specified parts to facilitate grease filling with grease guns). The exposed parts of the connection should be inspected and tightened.

Cleaning of various filters, carburetors, gasoline pumps, etc.

The emphasis on lubrication and fastening in the first-level maintenance is because in the initial operation of the car, the running parts have not been well run-in, especially the high-speed engine moving parts will have some metal chips falling into the oil, if not removed in time, it will aggravate the wear of the moving parts. The high temperature caused by the relative movement of each moving part at high speed will cause the grease to volatilize, and once dry friction is formed, the moving parts will be damaged quickly. Therefore, care must be taken to add grease regularly.

Many repairmen and car owners often do not pay attention to checking the fastening of the connectors, perfunctory, which is very dangerous, if there is negligence may cause a major accident.

At present, the automobile maintenance system implemented in China is divided into daily maintenance, first-level maintenance and second-level maintenance.

Daily maintenance is based on cleaning, ignoring and safety inspections, and is the maintenance work that the driver is responsible for.

In addition to the daily maintenance work, the first-level maintenance is a vehicle maintenance operation carried out by the maintenance company, which focuses on cleaning, lubrication, and fastening operations, and checks the relevant safety components such as braking and control.

In addition to the first-level maintenance work, the second-level maintenance mainly inspects and adjusts the safety parts that are easy to wear or disguise after a certain period of time, such as steering knuckles, steering rocker arms, brake shoes, suspensions, etc., and disassembles the tires and changes the tires. Vehicle maintenance work is carried out by maintenance companies to check and adjust the working condition of the engine and exhaust pollution control devices.

Secondary maintenance inspection items for vehicles.

1.After the engine passes the operation of three cleaning and three filtration, it should be easy to start, run smoothly, have normal exhaust (referring to the exhaust gas reaching the standard), water temperature and oil pressure meet the requirements, the speed is stable, there is no abnormal noise, the tension of each belt is moderate, and there is no four leakage (water, oil, electricity, gas).

2.The direction of free travel and toe meet the requirements, the steering is light, flexible and reliable, and the front wheels do not swing their heads left and right and deviate when driving.

3.The free stroke of the clutch meets the requirements, the operation is convenient, the separation is thorough, the combination is stable and reliable, there is no abnormal noise, and there is no oil leakage in the hydraulic system.

4.The gearbox, drive axle, universal joint (or half shaft) transmission device is well lubricated, the connection is reliable, there is no abnormal noise and overheating, no jumping, flexible shifting, and no oil leakage.

5.The free stroke of the brake pedal and the intermittent brake meet the requirements, the driving and parking brakes are good, there is no deviation and lag during braking, and the inertia proportional valve works normally without oil leakage.

6.The tire pressure is normal (different models have different high and low pressure standards).

7.The cantilever and shock absorption are fixed and reliable, the function is normal, and the temperature of the hub bearing is not high after driving.

8.Generators, starters, lights, instruments, signal lights, buttons, and switches are fully equipped and complete, and can work normally.

9.Lubricating oil is filled at each lubrication point of the whole car.

10.The whole car is rinsed and cleaned.

Generally, when the car travels to 1500 2000km, it is mainly fastened and lubricated. Level 1 maintenance is carried out when the car has not undergone too many kilometers, and the damage to the car at this time is minimal.

Prevent minor illness overhaul and disease-free overhaul: the car is originally a small fault is no problem, but some businesses will exaggerate the fault to report some unnecessary maintenance items, or even no fault, quote some unnecessary maintenance items to greatly increase the maintenance cost, if the consumer can not confirm whether the service is true, you can ask the staff to come up with the corresponding credentials. When repairing, you can understand what maintenance operations, and if there are no items beyond the initial agreement with the car service, you can ask the car service consultant and car repair master.

After the vehicle has reached a certain mileage (the interval mileage varies depending on the vehicle and the conditions of use), in addition to the daily maintenance work, the work content focusing on cleaning, lubrication, and tightening should be carried out

After the completion of the first-level maintenance operation, the car should be clean and tidy, firmly connected, three filters are unobstructed, no oil leakage, no water leakage, no air leakage, and no electricity leakage.

The main content is to change the engine oil and systematically check the amount of lubricating oil in each assembly, focusing on lubrication and tightening.

The focus of the inspection is on the oil level of the engine, transmission, braking system, power steering system and differential, as well as the level of the cooling system, cleaning system and battery.

Grease is added to the moving nodes according to regulations, the connectors of the exposed parts are inspected and tightened, and various filters, carburetors and gasoline pumps are cleaned.

Rinse the car clean, and the engine and chassis should be free of oil and mud after wiping.

1. Change the oil, oil filter, gasoline filter, and air filter. Usually change the car oil once every 5000km, and change the gasoline filter once every 20000km.

2. Check whether the position of the refrigerant level of the automobile meets the regulations. Usually the refrigerant needs to be replaced every two years.

3. Check the position of the liquid level of the brake and clutch. Brakes and clutch fluids are usually replaced every 30,000 km or two years.

4. Check whether the oil level of the steering power tank meets the regulations, and check whether there is oil leakage at the interface of each oil pipe of the system.

5. Check the liquid level of the battery and the liquid level of the glass cleaning agent tank, if the liquid level is too low or insufficient, it needs to be added or replaced.

6. Check the tightness of the belt of the generator, air conditioner, water pump and booster pump, whether it is aging, and replace it in time if it is found to be abnormal.

7. Check whether the front and rear lights of the car are complete (including: headlights, wide lights, turn signals, brake lights, reversing lights and fog lights), and confirm whether the brightness and illumination angle of the lights are up to standard.

8. Check the tire pressure and wear of the car, tighten the tire screws according to the specified torque, and the tire pressure is added to the specified value of the model, and the tire is transposed according to the wear and tear.

9. Check whether the exhaust emissions of the car meet the standard, if the exhaust emissions exceed the standard, it is necessary to check the fuel condition of the engine and whether the oil pipeline is normal.

Common maintenance includes: engine oil, oil filter, fuel filter, air filter, and cabin air filter.

Automobile manufacturers are equipped with a "car regular maintenance list" when each car leaves the factory, and the maintenance items and cycles are usually formulated based on the driving mileage, the purpose of which is to achieve the best performance of the car and prolong the service life of the car through regular maintenance.

Different manufacturers, different models, their maintenance items and cycles are also different. Therefore, it is necessary to maintain and maintain your car according to the car maintenance table.

For example, the following picture shows the regular maintenance table of a certain brand of car.

The first-level maintenance project of the car is the most basic routine inspection and maintenance of the car, which is mainly to replace the engine oil and refrigerant, check the tightness of tires, water pumps, booster pumps, etc., eliminate potential safety hazards, and maintain the performance of the car.

Level 1 maintenance is generally carried out when the car has traveled to 1500 2000km. It is mainly fastening and lubrication. The main contents are:

Check and tighten the loose bolts and nuts in the exposed parts of the car, add grease to the lubricating parts and add lubricating oil in each assembly according to the lubrication performance specifications, and clean each filter.

Secondary maintenance is generally carried out when the car travels 6000 to 8000km. The secondary maintenance is centered on inspection and adjustment, and a more in-depth technical condition inspection and adjustment is carried out on the vehicle with a certain mileage, the purpose of which is to maintain good operating performance of the vehicle for a long time in the future. The operation of secondary maintenance is more, in addition to all the work of primary maintenance, it is necessary to eliminate some faults and hidden dangers found in the maintenance work, and the maintenance time is longer, which is generally implemented by maintenance workers.

Cleaning or replacing engine air filters, air compressor air filters, crankcase ventilation air filters, oil filters and fuel filters requires that the filter elements of each filter should be clean and undamaged, and the upper and lower liners should be free of defects and well sealed; Each filter should be clean and securely installed. The maintenance of the car is to regularly inspect, clean, replenish, lubricate, adjust or replace some parts of the relevant parts of the car to do preventive work, in order to make the technical condition of the car normal, eliminate hidden dangers, prevent failures, slow down the deterioration process of parts, and extend the service life of the car.

Level 1 maintenance of the car is carried out by professional repairers. In addition to routine maintenance work, we focus on cleaning, tightening, and lubrication, and inspect safety parts such as braking and operation. The specific operation content of the first-level maintenance is as follows; 1. Clean the exterior of the car and each assembly.

It's a pseudo-concept, what is primary maintenance? Is it the first time to maintain? If it's the first maintenance, there's nothing to check 5,000 kilometers basically nothing can be broken You can look at the tires, brake pads, the tightening status of some chassis parts bolts, and nothing else can be checked.

We all know that the routine maintenance of the car is divided into small maintenance and major maintenance, small maintenance knowledge is simple to replace the oil and oil filter element, large maintenance is more troublesome and costly, basically all the routine maintenance items have to be replaced again. In fact, in the professional automobile circle, check the tire wear and tire pressure, and the front and rear wheels of the tire can be rotated poorly according to the situation. 5. Clean the oil tray and the front and rear hub bearings before changing the oil.

6. Check whether the bolts and nuts of the leakage part of the vehicle are loose and tightened.

clean the body and wipe the engine and chassis parts; Cleaning and maintenance of air filters; cleaning the gasoline filter; Clean the oil filter and replace the filter element according to the degree of contamination; Drain the oil and water accumulation from the gas tank. Hello, we often say that the first-level maintenance project of the car is the most basic routine inspection and maintenance of the car, mainly to change the oil, refrigerant, check the tires, water pump, booster pump tightness and other work, eliminate potential safety hazards, and maintain the performance of the car for the purpose of maintenance work.

The first-level maintenance is mainly to strengthen the firmware of the car, repair the problems of the starting engine of the car, check whether the engine of the car is noisy in various speeds, detect the tightness of the fan belt, change the oil, oil filter element, etc.

Changing the air cleaner, cleaning the engine, stabilizing the chassis, aligning the four wheels, lubricating the tires, etc., are all items to be done in the first level of car maintenance.

Mainly engine oil, oil filter, fuel filter, air filter, air conditioner filter, etc., mainly depression, internal cleaning.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Hello, after the completion of the first-level maintenance operation, the car should be clean and tidy, firmly connected, smooth three filters, no oil leakage, no water leakage, no air leakage, no electricity leakage.
