Household cars are maintained once a year for thousands of kilometers?

The first warranty is three months or 5,000 kilometers, and the next 5,000 kilometers is a maintenance.

The mileage of major maintenance is generally 80,000 kilometers.

Major maintenance needs to carry out a comprehensive inspection of the vehicle, check whether the chassis parts are aging and loose, the most common is the transverse tie rod, boom, plane bearing and buffer rubber, such as aging should be replaced, can reduce the abnormal noise of the chassis and increase the safety of driving.

The maintenance and replacement of transmission oil is the first to bear the brunt, because 80,000 kilometers have reached the transmission oil replacement cycle, and the replacement of transmission oil can change gears more smoothly, and the new transmission oil can also fully lubricate the gearshift mechanical structure in the gearbox, which can prolong the service life of the gearbox.

Engine oil and filter, spark plug, transmission oil filter, brake fluid, glass washing fluid, air, air conditioning filter, and antifreeze should be replaced and filled according to normal; Adjust the air pressure of the tires and check the wear and alignment of the four wheels, charge the spare tire to the specified air pressure, and test the battery for battery loss.

Items for minor 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 prolong the service life;

2. Oil filter, oil filter is a component that filters 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, impurities in the inhaled air, oil oxides, etc., are the objects of oil filter filtration;

3. The content of the major maintenance is to replace the engine oil and the regular maintenance of the oil filter, air filter, gasoline filter, etc. In addition to changing the oil and oil filter, there are the following two items in the car maintenance;

4. Air filter, the engine should suck in a large amount of air during the working process, if the air is not filtered, the dust will accelerate the wear of the piston group and the cylinder, the gasoline filter, the role of the gasoline filter is to provide clean fuel for the engine, filter out the moisture and impurities of the gasoline. This optimizes engine performance and provides the best possible protection for the engine.

Generally speaking, the regular items of the third maintenance of the car are to replace the oil, oil filter, air filter, air conditioning filter, spark plug, etc., some brand manufacturers will add some additional maintenance items, the reason for this factor depends on the service life of auto parts, the service life of some accessories is short, and it is easy to get dirty, so it should be replaced frequently, and some accessories have a longer service life.

Among them, replacing the engine oil and oil filter element is a necessary item, because the shelf life of the engine oil in the harsh environment of high temperature and high pressure will be greatly shortened, and 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. Both the oil and the oil filter are changed at the same time.

Possible maintenance is:

1. Clean or replace the air filter, generally clean it every 5,000 kilometers, and replace the air filter after 10,000 kilometers. It can reduce the wear of cylinders, pistons and piston rings and other parts to clean or replace the oil filter, when the lubricating oil must be changed at the same time, otherwise the quality of the lubricating oil will be affected. Generally, it is replaced once every 5000 km.

It can avoid impurities from mixing into the engine oil during the use of the internal combustion engine, and prevent the wear of moving parts and the blockage of the oil circuit.

2. Clean or replace the fuel filter, in order to ensure that the engine runs well, the replacement cycle of the fuel filter is generally 20,000 kilometers or 1 year. It can prevent cylinder wear caused by impurities and moisture mixed in the process of gasoline storage, transportation and filling. These are all theoretical.

It usually depends. These three replacements are commonly known as "three filters", which are high and expensive in terms of working hours. 20,000 kilometers should not be too high in man-hours, you can consider it.

As the saying goes"Three points of cultivation and seven points of nourishment"It is very important to maintain the car, and the maintenance of the car should pay attention to the following six systems for special maintenance:

1. In-depth maintenance of lubrication system.

The main function of the lubrication system is to effectively lubricate the various parts of the automobile engine to prevent excessive wear. Under normal circumstances, the car needs to be cleaned and maintained every 5000km-10000km, and it needs to be cleaned and maintained once when the engine noise is too loud, the acceleration is weak, and the water temperature is too high. Clean the sludge and other accumulations inside the engine to avoid oxidation thickening of the oil at high temperature, reduce the wear of engine parts, prolong the life of the engine, and improve the engine power.

2. Cleaning and maintenance of the fuel system (i.e., cleaning the nozzle and valve carbon deposit).

Under normal circumstances, the car needs to be cleaned and maintained once every 10,000km-15,000km, or when you find that the engine is shaking, sluggish and poor acceleration, black smoke, weak and fuel-efficient. Remove gum and carbon deposits from the inside of the system to prevent harmful corrosion, avoid and stop leaks in seals and tanks, and replace old coolant completely.

3. Cleaning and maintenance of cooling system.

Under normal circumstances, the car should be cleaned and maintained once during the change of seasons in winter and summer, and once every 6 months to 8 months during normal driving, or once when the water temperature is too high, leaking, and boiling. Remove traces and limescale that cause engine overheating, prevent harmful corrosion, avoid and stop leaks in seals and water tanks, and replace old coolant completely.

Fourth, the cleaning and maintenance of the gearbox (automatic transmission gearbox).

Under normal circumstances, the car is cleaned and maintained every 20,000km-25,000km, or when the gearbox is slippery, the water temperature is high, the gear shift is slow, and the system leaks. Removes harmful sludge and varnish deposits, restores the elasticity of gaskets and O-rings, smooths transmission shifts, improves power delivery, and completely replaces old automatic transmission fluids.

5. Cleaning and maintenance of power steering system.

The car needs to be cleaned and maintained every 40,000km-45,000km, or in case of steering difficulty system leakage, after replacing the power steering accessories, it must also be cleaned and maintained. Remove harmful sludge and paint film from the system, remove steering difficulties at low temperatures, stop and prevent leakage of power steering fluid, remove steering noise, and completely replace old brake steering fluid.

6. Cleaning and maintenance of the braking system.

The car is cleaned and maintained every 50,000km, or when ABS reacts too early and too slowly, it is cleaned and maintained. Remove the harmful sludge paint film in the system, remove the danger of work failure at ultra-high temperature or ultra-low temperature, effectively prevent the brake fluid from deteriorating and expiration, and completely replace the old brake fluid.

Maintenance every 5000 km or half a year, and oil change every 5000 km. Replace the air and oil filters every 10,000 km. 20,000 km to change fuel filters and spark plugs.

1.The content of minor maintenance: Minor maintenance generally refers to the routine maintenance items carried out within the time or mileage specified by the manufacturer in order to ensure the performance of the vehicle after the vehicle has traveled a certain distance.

Different brands of mineral oil, semi-synthetic oil, and synthetic oil have different shelf lives. Refer to the manufacturer's recommendations. Oil filters are generally divided into conventional and long-life oil filters.

The traditional oil filter is replaced with oil, and the long-life oil filter lasts longer. 3.Small maintenance supplies:

1。Engine oil is the lubricant that runs the engine. It lubricates, cleans, cools, seals, and reduces wear and tear on the engine.

This is of great significance to reduce the wear and tear of engine parts and extend the service life. 2.The oil filter cartridge machine is a component used to filter engine oil.

Engine oil contains a certain amount of colloids, impurities, moisture and additives; During the working process of the engine, the metal chips generated by the friction of various parts, the impurities in the inhaled air body, the oil oxides, etc. They are all the objects of oil filter filtration. If the oil is not filtered, it will directly enter the oil circuit, which will adversely affect the performance and life of the engine.

The regular maintenance is about 5,000 kilometers, and if you use fully synthetic engine oil, it can also reach about 10,000 kilometers to change.

Family cars are generally maintained once every 5,000 to 8,000 kilometers.

After buying a car, no matter how much you use, the maintenance is always old, and the most frequent is the third filtration of the engine oil, but it does not mean that these are the only ones that need to be maintained. When a certain number of kilometers or hours have been driven, other oil on the car also needs to be replaced, and there is major maintenance. So how many kilometers is this major maintenance, and what are the projects?

The average family car needs a major maintenance for three years or 60,000 kilometers. Whichever one comes first, repair it as soon as possible. However, when it comes to one of them, there is no need to repair it immediately, and it can be postponed for a period of time according to the actual situation of the car.

For example, it took 3 years to run 20,000 kilometers. Do you still need major maintenance? There was no problem with this situation in the first half of the year, but it was better to maintain it on time.

If it reaches 60,000 kilometers, even if it does not take three years, it should be maintained immediately, because kilometers are a very important reference index. What are the main maintenance items? Maintenance does not refer to the failure of certain projects, but there are many parts that need to be replaced, as well as various fluids of the whole vehicle.

Except for the engine oil, all the other engine oil in the car can be changed together in three years or 60,000 kilometers, because sometimes some engine oil is replaced after using up to half of it, which is very wasteful. Clean carbon deposits, replace spark plugs, replace timing belts, replace batteries, etc. It is also a maintenance item for the car.

Some parts that need to be replaced will also be replaced. Among the many parts, the battery is also one of the more important ones. Half of the battery's lifespan is about three years.

If you don't have good habits, it's likely that the battery will be scrapped soon.

When driving 60,000 kilometers, the carbon deposits should be cleaned up twice. Generally, it should be cleaned once after driving 30,000 kilometers. However, if the carbon deposits are not cleaned for 30,000 kilometers, it is best to choose to dismantle and wash them directly, because the carbon deposits at this time can not be cleaned without dismantling and washing.

The service life of spark plugs is generally about 40,000 kilometers, but many car owners continue to use them when they think that there is no need to replace them. At 60,000 km, it must be replaced in time, otherwise fuel consumption will increase and power will decrease. Platinum spark plugs do not need to be replaced yet.

Replacement takes 8-100,000 km. At the same time, inspect all parts of the vehicle, such as brake pads, brake discs, wiper blades, oil seals, and rubber hoses, etc. There is no definite number of kilometers for these parts, so as long as they are worn to a certain extent, they must be replaced once no matter how many kilometers they have traveled.

Major repairs refer to the repair of all problems with the whole vehicle. All kinds of oil in the car must be replaced, because the oil also has a shelf life. If the oil is used again after it has expired, it will exacerbate the wear and tear of the last part of the vehicle.

Some parts can be replaced according to the actual level of wear, and things that are determined by slip time or kilometers are best done together. When it comes to the time or kilometers of vehicle maintenance, it must be done in a timely manner. After the vehicle is repaired, it can not only improve the performance of the vehicle, but also ensure the service life of some parts.

Millions of car purchase subsidies.

Private cars are 40,000 kilometers to do a major maintenance.

However, this time is not fixed, and some models may be 60,000 kilometers for a major maintenance.

Specifically, it should be carried out at the time specified in the maintenance manual (vehicle instruction manual). All of them are described in detail.

Major maintenance is based on minor maintenance. The usual minor maintenance only needs to change the oil and filter, and the major maintenance needs to do more items.

In addition to the oil and filter, major maintenance – generally the following items need to be done:

1. Replace the air filter, air conditioning filter, and fuel filter. 2. Transmission oil. 3. Brake fluid. 4. Antifreeze coolant. 5. a spark plug.

The above basically needs to be replaced.

In addition, tires and brake pads should be checked and replaced in time if they are found to be severely worn. The replacement time of these two parts is relatively different due to the influence of various objective factors. However, it is generally about 40,000 to 60,000 kilometers to replace.

And then there is the timing belt. The timing belt is also a very important part, and it is also a part that many people are prone to hunger. Check to see if the timing belt is aging, and if the void god finds an abnormality, it should also be replaced in time.
