What are the contents of car maintenance? What are the major car maintenances?

Major maintenance refers to the routine maintenance of oil and oil filters, air filters, and gasoline filters at the time or mileage specified by the manufacturer.

First, change the oil of the whole car (**depending on the car brand).

1.Oil. There are many brands of engine oil, Castrol, Mobil, Shell, etc., and the ** per liter is about 90-120 yuan.

2.Transmission fluid.

The manual transmission oil is slightly cheaper, and it is about 200 yuan after replacement. Automatic transmission is 50-120 yuan per liter, and Volkswagen Audi adds relatively more.

3.Brake fluid.

Replacing the brake fluid requires four wheels of exhaust, and adding one liter is enough, ** at about 200 yuan.

4.Booster oil.

Now many models are electronically assisted, there is no booster pump, according to the actual situation, ** in about 200 yuan.

5. Rear axle oil. Rear-wheel drive cars have rear axle oil, and rear axle oil is generally common with gear oil, ** at about 150 yuan.

6.Front axle oil, divided into heavy tank oil.

These two oil four-wheel drive vehicles are available, and each ** is about 150 yuan.

Second, clean up carbon deposits.

Cleaning up carbon deposits is generally what we often talk about"Sanqing"Throttle, fuel injector, intake, ** at about 300 yuan. Whether the three-way catalysis is cleaned or not can be determined according to the actual situation.

Third, replace the spark plug.

The spark plug is replaced every 30,000 kilometers, and each spark plug ** ranges from 30-120 yuan, four cylinders need to be replaced, six cylinders need to be replaced with six, and so on.

Four. Examine. 1.Antifreeze.

Antifreeze is generally replaced every three years or so, and the freezing point can be checked with a freezing point meter.

2.Brake pads, brake discs.

Brake pads are usually used for about 60,000 kilometers, and the degree of wear is related to their own braking habits. The brake disc is usually replaced twice, and the brake pads are replaced once.

3.Tires, four-wheel balance, four-wheel alignment.

Tires are usually replaced in three years or 80,000 kilometers to check whether the tires are sporulous, eccentric and other symptoms.

4.Chassis. Check whether the supporting arms, ball joints, tie rods, etc. of the chassis are aging, oil leakage and other phenomena.

Usually, the whole car needs to be inspected for major car maintenance, check whether there is oil leakage and water seepage, and detect it as soon as possible. And the tires, steering, and brakes are the top priorities.

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.

1. Engine oil: Engine oil is the lubricating oil for engine operation. It can lubricate, clean, cool, seal, reduce wear and other functions of the engine.

It is of great significance to reduce the wear and tear of engine parts and extend the service life. 2. Oil filter element: The oil filter element is a component that filters engine oil.

Engine oil contains a certain amount of gum, impurities, moisture and additives; In the process of engine work, the metal chips generated by the friction of various parts, the impurities in the inhaled air, and the oil oxides are all the objects of the oil filter element. If the oil is not filtered and goes directly into the oil circuit, it will have a detrimental effect on the performance and life of the engine. 3. Gasoline filter element:

The function of the gasoline filter is to provide clean fuel to the engine and filter out the moisture and impurities of the gasoline. This optimizes engine performance and protects the engine. The number of major maintenance maintenance:

1. Use the appropriate grade of engine oil to change the oil and filter element regularly (every 5000 km); 2. Maintain the air filter frequently and replace it regularly (every 20,000 kilometers); 3. Clean the fuel system regularly, and replace the fuel filter element regularly (every 30,000 kilometers); 4. Regularly (30,000 km) maintenance of the water tank cooling network; 5. Replace the spark plug regularly (40,000 kilometers or driving conditions).

The items of car maintenance are to change the engine oil and oil filter, air filter, and gasoline filter. The following is an introduction to the car maintenance section:

1. Oil filter: Provide clean fuel for the engine and filter out the moisture and impurities of gasoline.

2. Air filter: A large amount of air should be sucked in during the working process, which will accelerate the wear of the piston group and cylinder.

3. Gasoline filter: Provide clean fuel for the engine and filter out the moisture and impurities of gasoline.

The usual items for major maintenance are: changing the engine oil and oil filter, air filter, and gasoline filter. In addition, depending on the situation of the century, it is also necessary to replace key components such as brake fluid, antifreeze, transmission fluid, timing belt, etc.

20,000 is the medium insurance, and the major maintenance is carried out every 40,000 kilometers. Major maintenance includes oil, filter, air and air conditioner filter changes, as well as some routine check-ups.

Common major maintenance of the car: change the oil, oil filter, fuel filter, air filter, and if necessary, replace other parts damaged during daily use.

The car overhaul includes the following:

Major car maintenance includes changing engine oil, oil filter, air filter, fuel filter, air conditioning filter, cleaning throttle, replacing antifreeze, brake fluid, and checking the spark plug for carbon deposits.

Expansion: 1. Major maintenance is carried out in turn with small maintenance, generally 10,000 kilometers for a small maintenance, 20,000 kilometers or 40,000 kilometers for a major maintenance. The best effect is to change the oil and change the oil filter element at the same time during major maintenance.

2. The maintenance is mainly to ensure the safety of the car and increase the life of the car, which is basically a comprehensive inspection of the car. The appearance is to check whether the tires are cracked and whether the body is bumped.

Major maintenance refers to the maintenance done once in 60,000 kilometers, replacing some things that are not often changed, such as brake fluid antifreeze, transmission fluid and the like.

Search for it yourself or ask 4S directly, and you'll know it.

1. Use the appropriate grade of engine oil to change the oil and filter element regularly (every 5000 km);

2. Maintain the air filter frequently and replace it regularly (every 20,000 kilometers);

3. Clean the fuel system regularly, and replace the fuel filter element regularly (every 30,000 kilometers);

4. Regularly (30,000 km) maintenance of the water tank cooling network;

5. Replace the spark plug regularly (40,000 kilometers or driving conditions).

Major maintenance is based on minor maintenance, and in addition to the engine oil and oil filter, the replacement of maintenance products has added air filter, gasoline filter and spark plug. These three types of filters play the role of filtering dust in the air and impurities in gasoline respectively.

The normal operation of the engine is based on the rational use of various maintenance products. If the oil filter is not replaced in time after the service life is reached, it will have a negative impact on the engine performance. The three filters refer to the air filter, the oil filter, and the gasoline filter.

The filter is used to filter impurities, and the three filters play the role of filtering dust in the air, sludge and carbon deposits in engine oil, and impurities in gasoline. In addition, after driving a long distance, the car also needs to replace key components such as brake fluid, antifreeze, transmission fluid, timing belt, etc.

The main items of vehicle maintenance are: replacing the engine oil and the regular maintenance of the oil filter, air filter and gasoline filter.

1. an engine system;

2. a gearbox system;

3. Air conditioning system;

4. a cooling system;

5. Fuel system, power steering system, etc.

<> "What is included in car maintenance.

I believe that many car owners have heard that car maintenance is divided into major maintenance and small maintenance, so what does car maintenance include air care? How often should car maintenance be done?

Since the replacement cycle of car parts is not the same, this is why the items of maintenance may be different every time. The duration of minor maintenance depends on the effective time or mileage of the oil and oil filter used, and major maintenance is to add other maintenance items on top of the minor maintenance. Generally speaking, minor maintenance alternates with major maintenance, and how often it is done depends on the manufacturer's arrangement.

Many manufacturers are required to maintain every 20,000 kilometers at intervals.

What are the specific items to be done for car maintenance? Generally speaking, changing the oil and oil filter is a must-do for every maintenance. Because the shelf life of the engine oil in the harsh environment of high temperature and high pressure in the engine will be greatly shortened, the performance will be greatly reduced, and the engine will not be protected over time.

In order to prevent impurities from mixing into the oil and causing oxidation, the oil filter element produces gum and sludge to block the oil circuit.

The function of the air filter is to block the dust and particles inhaled by the engine during the air intake process, if the filter is not clean for a long time, it will lead to the inhalation of dust in the engine, resulting in abnormal wear and tear of the cylinder wall bucket stove. The air filter must also be replaced during major maintenance.

Cabin air filters and air filters work similarly to each other, filtering out impurities and large amounts of dust, and then delivering the cleaning air to the car. The general cabin air filter will also be replaced in major maintenance, and it is also possible to replace it in small maintenance, the key is that the air conditioning filter is not expensive, and there is no difficulty in replacement, and the owner can consider replacing it by himself.

In addition to changing the oil and three filters, major maintenance may also involve the replacement of other accessories. When the vehicle is used for a certain number of years or after a certain mileage, it will enter the maintenance period, and the maintenance cost is relatively high.

All car owners can do is to arrange the maintenance cycle reasonably and make full use of the free testing activities of the 4S shop, although it seems that there is no substantive content in the eyes of the car owner, it is actually very beneficial. Car owners can use these free inspection activities to conduct a comprehensive physical examination of their cars, find some potential faults in time, and eliminate these hidden faults, saving high maintenance costs in the future.
