2.Inspection operation inspection operation is one of the important work of automobile maintenance, through the inspection of various parts of the car, the variation and damage of parts can be determined. The main content of the inspection operation is to check whether the assembly and parts of the car are complete, whether the connection is tight, and whether there is water leakage, oil leakage, air leakage and electricity leakage; Utilize the vehicle diagnostic device such as the indication instrument, the alarm device on the car, check the technical status of each assembly, mechanism and instrument; Strengthen inspections on the work conditions such as steering, braking, and lights that affect the safe driving of automobiles; Check the fitting clearance of each major component when dismantling, assembling or adjusting the car.

It is stipulated that the maintenance operation content of the vehicle is: cleaning, inspection, replenishment, lubrication, fastening, adjustment, etc., except when the main assembly fails and must be disassembled, the vehicle shall not be dismantled at will. Daily check-ups are:

Brakes and brake oil levels. Oil level. Water tank.

Battery connectors. Tire pressure. front and rear lights, etc.

l) Daily maintenance is a routine operation, which is carried out by the driver, and the content of the operation center is: cleaning, supply and safety inspection.

2) The first level of maintenance belongs to the regular mandatory maintenance operations, which are carried out by professional repairmen, and the content of the operation center is mainly cleaned, lubricated and fastened in addition to daily maintenance operations, and the safety components such as braking and manipulation are checked.

3) The secondary maintenance belongs to the regular mandatory maintenance operations, which are carried out by professional repairmen, and the content of the operation center is in addition to the first-level maintenance operations, focusing on inspection and adjustment, and dismantling and inspecting tires and transposing tires. At the same time, the secondary maintenance of the vehicle should be carried out before the detection and diagnosis and technical assessment, according to the results, determine the additional operation or minor repair items, combined with the secondary maintenance.

4) The quality of running-in maintenance is directly related to the length of the life of the car. Doing a good job of maintenance during this period will be conducive to the run-in of automobile parts. The maintenance work during the run-in period of the car is mainly cleaning, lubrication, fastening and other items.

5) Where the minimum temperature of the whole year is below 0, seasonal maintenance is required before the beginning of summer and winter. Seasonal maintenance is generally completed by the driver, and the content of the operation center is to replace the lubricating oil and coolant that meet the seasonal temperature requirements, adjust the fuel supply system and charging system, and check the working condition of the cooling system, heating or cooling system.

The national standards for modern automobile maintenance operations and the maintenance standards of automobile manufacturers provide a detailed introduction to the maintenance standards and methods of various systems of automobiles, including six modules, including automobile maintenance overview, engine system maintenance operation, air conditioning system maintenance operation, chassis system maintenance operation, electrical system maintenance operation, maintenance process operation and corresponding training project operation. Cleaning is the foundation of car maintenance, including exterior cleaning and interior cleaning. Its significance is not only to make the car appearance and parts neat and beautiful, so that the follow-up inspection and adjustment work can be carried out smoothly, but more importantly, to prevent its performance from deteriorating due to non-cleaning.

Vehicle maintenance operations include inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle.

The purpose is to keep the car clean and tidy, the technical condition is normal, eliminate hidden dangers, prevent failures, slow down the deterioration process, and prolong the service life. Automobile maintenance is based on the law of the change of automobile technical conditions with mileage, and stipulates the content of different levels of operation items.

According to the regulations of the Ministry of Communications, China's current automobile maintenance system is divided into daily maintenance, first-class maintenance, second-level maintenance, etc. In addition, there is seasonal maintenance and walk-in maintenance.

It is stipulated that the maintenance operation content of the vehicle is: cleaning, inspection, replenishment, lubrication, fastening, adjustment, etc., except when the main assembly fails and must be disassembled, the vehicle shall not be dismantled at will.

Daily inspections are: 1. Brake and brake oil level. 2. Oil level. 3 water tanks. 4. Battery connector. 5. Tire pressure. 6. Front and rear lights, etc.

In order to prevent accidents and ensure driving safety, the technical condition of the car should be understood and mastered at any time, and the driver must insist on daily maintenance when the car is in use. The main content of the daily maintenance of the car is to adhere to the "three inspections", that is, to check the safety mechanism of the vehicle and the fastening of the connection of various parts before leaving the car, during the driving and after the car is collected; Maintain the "four clean", that is, keep the oil filter, air filter, fuel filter and battery surface clean; Prevent "four leaks", that is, to prevent oil leakage, water leakage, air leakage and electricity leakage; to keep the car clean and in good condition. The car is prescribed as follows: routine maintenance items.

Routine vehicle maintenance matters:

1. The front driving wheel and the diagonal tire should be replaced every 5,000 kilometers of the car, which can prolong the tire life and reduce the wear of the driving wheel. (Four-wheel drive is the same diagonal reversal).

2. Regularly clean up stones and other foreign objects in the tire tread. When the tires are running on the ground, they often embed small stones and other things, and these foreign objects can easily cause danger when the wheels are driving at high speeds, so it is necessary to clean them regularly.

3. Remove bird droppings, dust and other dirt on the surface of the car in time. Over time, these contaminants can damage the paint finish and cause the surface of the car to be no longer shiny.

4. Always check whether the water level of the car water tank is normal. The water tank of the car should ensure that there is enough water, so as to maintain the normal start and operation of the car.

5. Always check whether the oil of the car is normal. Engine oil is the lubricant for the good functioning of a car, and its importance cannot be overstated. Therefore, check that the oil gauge is within the normal range after the car has cooled down.

This question is unknown to laymen, and we insiders are also confused.

1.Cleaning operations.

Cleaning is the basis for improving the quality of vehicle maintenance, preventing corrosion of parts, reducing wear and tear on components, reducing fuel consumption, and preparing for inspection, tightening, adjustment, lubrication and replenishment operations.
