What are the regular maintenance of the car and what is the content?

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 of 1500 to 2000 kilometers, it is carried out by the maintenance worker and 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. To fill grease to the moving nodes according to the regulations There are generally grease nozzles in these specified parts, which is convenient for filling grease with a grease gun. 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. The secondary maintenance is centered on inspection and adjustment, in addition to the implementation of the primary maintenance work, it is also necessary to replace the three filters, namely: oil filter, fuel filter and air filter, check and adjust the engine, braking system and electrical equipment, tire rotation, etc.

This part of the work is more professional and is generally carried out by professional maintenance workers. Secondary maintenance is a more comprehensive inspection, through which it exposes and solves the existing faults to ensure that the components of the car and the performance of the whole vehicle are in a normal state, which plays a very important role in the maintenance of the car. However, the most common problem is that the repairman often only replaces the three filters, changes the oil, and makes a perfunctory inspection, which is far from the requirements of secondary maintenance.

In addition to checking with a comprehensive engine inspector, some auto repair shops still have certain difficulties, and it is necessary for car owners to supervise the repair shops to fully complete the specified operations.

Minor maintenance generally refers to the routine maintenance items done at the time or mileage specified by the manufacturer to ensure the performance of the vehicle after the car has traveled a certain distance. This mainly includes changing the oil and the oil filter. Intervals for small maintenance:

The duration of minor maintenance depends on the oil used and the effective time or mileage of the oil filter. The expiration date of mineral engine oil, semi-synthetic engine oil and fully synthetic engine oil is also different for different brand levels, please refer to the manufacturer's recommendation. The oil filter element is generally divided into two types: conventional and long-lasting, and the conventional oil filter element is replaced with the oil, and the long-term oil filter element lasts longer.

Supplies in minor maintenance: Engine oil is the lubricating oil that runs the engine. 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. The oil filter is the part that filters the oil.

Secondary maintenance is also known as secondary maintenance, which is customarily referred to as secondary maintenance. In addition to performing first-level maintenance work, it is necessary to replace oil filters, fuel filters, and air filters, inspect and adjust engines, brake systems, and electrical equipment, and perform tire rotation. This part of the work is more professional and is generally carried out by professional maintenance workers.

In addition to the implementation of the first level of maintenance of the operation content, the second guarantee also added the following items: use the electronic fault diagnostic instrument to check the fault system, if a part of the fault should be reported to the owner, timely repair. The use of an integrated engine tester to comprehensively test the characteristics of the engine is gradually being promoted, so as to determine the items that need to be overhauled and adjusted.

Check the cylinder pressure, and when possible, a non-disassembly cleaner should be used to clean the oil circuit of the engine to remove carbon deposits, grease and gumming. Clean the carburetor and fuel pump and, if necessary, adjust it on the test bench.

<> "Daily maintenance items mainly include the replacement of engine oil and oil filters, the maintenance and replacement of air filters, gasoline filters and pollen filters, and the inspection items and maintenance of spark plugs, transmission oil and other related systems.

1.Oil and oil filter changes are mainly for the maintenance of the lubrication system. The main function of the lubrication system is to effectively lubricate the various parts of the automobile engine and prevent excessive wear.

The function of the oil filter is to remove all kinds of impurities in the oil and ensure the normal lubrication system. When changing the oil, the oil filter should be changed along with the oil. Under normal circumstances, the car needs to be serviced every 5000 km.

2.The function of the air body filter element is to filter the empty cherry limbs before the gas enters the cylinder to remove impurities, dust, sand and other foreign substances entrained in it. The cleaning and maintenance of air air filter elements depends on the environment in which they are used.

When driving to 20,000-25,000 kilometers, the gasoline filter element is generally replaced.

3.Spark plugs are consumables and are replaced every 20,000 km. In addition, brake fluid, transmission fluid, battery, throttle, fuel injector, brake pads and other components are all inspection items during daily maintenance, and maintenance is carried out according to the use of the product.

Routine Maintenance Intervals:

1.10,000 kilometers of small maintenance is machine filter and three filters: machine filter, air filter and steam filter.

20,000 km minor maintenance is the intermediary, and major maintenance is carried out every 40,000 km. 20,000 km maintenance and replacement of oil, filter, air filter and air filter, as well as some routine inspections: Air air filter:

Proper installation of an air filter can reduce wear and tear on parts such as cylinders, pistons, and piston rings. (Generally, it is cleaned every 5,000 kilometers, and the air filter must be replaced every 10,000 kilometers).

2.Oil filter: Proper installation of the oil filter prevents impurities from mixing into the oil during the use of the internal combustion engine, preventing wear of moving parts and blockage of the oil circuit.

Tuyue Tube reminds you that when you change the lubricating oil, you must change the oil filter at the same time, otherwise the quality of the lubricating oil will be affected. The interval between changing the oil and the oil filter is generally 5000 km.

3.Fuel Filter: Proper installation of a fuel filter can prevent cylinder wear and tear caused by impurities and moisture contamination during storage, transportation, and refueling. In order to ensure the good operation of the engine, the replacement interval of the fuel filter is generally 20,000 km or 1 year.

Note: The "three filters" maintenance must be carried out by professional maintenance personnel, because it involves some professional maintenance tools, and it is very difficult for car owners to do it themselves.

<> "What are the common sense of regular car maintenance?

Nine things to know about car maintenance.

1. Three major filter elements.

The three major filter elements of the car are equivalent to the lungs of the human body, filtering the pure body, and it is clear that the three major filter elements of the car are: oil filter, air filter, and air conditioning filter. To change the oil, you need to change the oil filter, and if there is a peculiar smell, you need to check the air conditioner filter.

2. Engine oil. The lubrication and speed of the engine after the car has been used for a long time, the rotation of the gears, and the oil have a great impact on this aspect, and the oil is equivalent to the lubricant of the engine has a great impact on the service life of the car. The car should change the oil every 5000 km to 7000 km, change the oil to confirm whether the height of the oil is between "L" and "H", after adding the oil, make sure that the oil gauge light must be displayed between the F and L lines.

3. Coolant.

The thermometer of the car is recommended to be replaced once every 40,000 kilometers, and the heat engine state should not be opened, and the liquid level of the radiator should be between full and low, and mineral water and tap water should not be added.

4. Brake fluid (i.e. brake fluid).

Brake fluid is equivalent to the life insurance of the car's safety system, it is recommended to replace it once in 40,000 kilometers, the brake agent needs to be between high and low, toxic corrosion** Note that the same type of brake fluid and clutch oil is an oil.

5. Transmission oil.

The automatic transmission should be changed at 40,000 kilometers, according to statistical analysis, 90% of the automatic transmission is not regularly replaced, so there is a failure, if there is time, it is recommended to check once every 6 months.

6. Storage and panicle battery.

The service life is 2-3 years, and the battery light needs to be checked regularly for damage.

7. Brake pads.

Replace once every 50,000 kilometers, and the carbon deposits should be removed regularly.

8. a spark plug.

The material of the spark plug is different and the service life replacement time is different, the copper-nickel spark plug should be replaced at 3 50,000 kilometers, the platinum spark plug should be replaced at 6 8 kilometers, and the iridium spark plug should be replaced at 10 kilometers.

9. Tires. Generally, it is replaced within 30,000 to 50,000 kilometers, and the tire pressure needs to be checked once a month to check whether there are foreign objects stuck and whether there are bubbling bubbles.

<> What is the significance of regular car maintenance?

The significance of regular maintenance of cars is to discover the potential safety hazards of the car in time and ensure the normal driving safety of the car.

There are a large number of parts and components working at the same time during the operation of the car, and after a long period of use, these parts will be subject to wear, aging or corrosion, resulting in the performance of these parts of the cautious parts.

Regular maintenance of the car can adjust and replace parts to maintain the performance of parts, so that passengers can have a simpler and safer driving experience.

<> What is the significance of regular car maintenance?

The significance of regular car maintenance is similar to human metabolism, which is to maintain the normal operation and function of the car.

For example, engine oil, it is like human blood before it is consumed, and it will accumulate filth over time, affecting the normal operation of the engine, and then it is necessary to change the new engine oil to keep the engine running.

The same is true for other accessories, and the leather plays a different role in the normal operation of the car.

There are many types of items that are regularly maintained, and the items that are maintained by each car manufacturer are generally the same. There are many items in the regular maintenance of the project is not easy to damage in the normal driving state, so only need to be checked, today, easy to repair the car network for you to explain such as: tire slip situation, brake effect and pedal clearance, hand brake effect, clutch clearance and clutch oil volume, steering wheel clearance, air conditioning system, instrument function, seat belt and warning system, power windows, sunroof, mirrors, lights, wipers, horns, antennas, ** control lock, battery fluid, air conditioning compressor belt, Distributor cover and distributor head, high-voltage line, ignition timing, idle speed and exhaust gas, power steering system, gasoline pipe, transmission shaft dust jacket, exhaust pipe silencer, suspension fixing nut (chassis inspection), tires and wheel discs, wheel bearings, front brake liner pump oil pipe, deceleration secondary air suction system, active crankcase ventilation system, evaporative exhaust gas control system, intake air temperature control system, coal contact converter and oxygen sensor, etc., if the above equipment is damaged (abnormal) after inspection, It will only be replaced or adjusted by the maintenance plant.

When the new car has traveled 1,000 kilometers, the engine oil, oil filter and transmission oil need to be replaced, because all the parts of the new car are completely new combinations, so they cannot be completely sealed smoothly when they come into contact with each other, for example, the friction between the piston and the piston rings, the gears in the gearbox, etc., will produce small residues after friction, and these residues will flow into the oil and transmission oil that lubricate the parts.

Spark plugs are replaced about once every 20,000 kilometers, and some car manufacturers replace them once every 30,000 kilometers.

Some items only need to be lubricated when they are reached, such as: door buckles, throttles and pile heads; The oil pipe of the rear brake pad pump is cleaned in 10,000 kilometers, and then cleaned again every 10,000 kilometers; In addition, the valve lash is adjusted every 20,000 km. And some oils and parts need to be replaced as soon as the mileage (or time) is up, such as:

Engine oil needs to be changed at the first 1,000 km and every 5,000 km. The oil filter is replaced every 1,000 km and then every 10,000 km. After the transmission oil is changed every 1,000 km, it is changed again every 20,000 km; The coolant of the water tank should be checked at every scheduled service, but it needs to be replaced every 20,000 km; The air filter is replaced every 20,000 km (every 5,000 km, the maintenance plant will clean it for you); The gasoline filter is changed every 20,000 km; The spark plug will be inspected every 10,000 kilometers and replaced every 30,000 kilometers. brake fluid is changed every 40,000 km; The generator belt and power steering pump belt are replaced every 50,000 kilometers; The timing belt is replaced every 70,000 km.

At each scheduled service, the workshop will check that your car's water tank coolant is adequate or leaking. The coolant of the water tank can be distilled water or ordinary water.
