Car maintenance has the following basic content:
1, regular replacement of oil: oil is the engine lubricant, the engine can play a lubrication, cleaning, cooling, sealing, wear reduction and other roles, but also the engine's ‘blood’.
2, regular replacement of three filters: three filters refers to the air filter, oil filter and petrol filter. Three filters can provide the effect of filtering impurities for the engine, the engine to play a protective role, but also to improve the efficiency of the engine.
3, power steering fluid: power steering fluid is commonly known as the direction of the oil, to regularly check whether there is a leak or obvious noise. Electronic power models are maintenance-free, so there is no need to replace the direction oil. The maintenance cycle of the direction oil is about 60,000 kilometres.
4, brake fluid: brake is quite important for driving safety, brake fluid has a strong water absorption, can automatically absorb moisture in the air.
5, coolant: coolant to ensure the normal work of the engine, to regularly check the coolant level is in the standard value, regularly check the coolant pot has no leakage, the average driving a year will need to replace the coolant.
6, battery: the battery is used to ensure that the engine can start normally, in the upper part of the battery observation window to check the ‘electric eye’ colour is green. The life of the battery is generally about two years, in the case of cold weather life may be shorter.

As cars are an important means of transport in our daily lives, their maintenance is crucial. Proper maintenance can not only extend the life of the car, but also improve performance and safety. The following is a detailed introduction to the correct method of car maintenance and related notes.
Regular oil and filter replacement
Motor oil is like the ‘blood’ of the car, playing the role of lubrication, cooling and cleaning the engine. It is generally recommended to change the oil every 5,000 to 10,000 kilometres, and replace the oil filter at the same time. It is also important to choose the right type of oil, according to the vehicle's operating environment, age and engine type to determine.

Tyre Maintenance
Tyres are the only parts of the car in contact with the ground, and their condition directly affects driving safety. Regularly check the tyre pressure and keep it within the range specified by the manufacturer. At the same time, pay attention to the wear and tear of the tyres, and replace them in time if the depth of the tread is less than 1.6 mm. In addition, every time you drive a certain mileage, you should change the position of the tyres to balance the tyre wear.

Braking system maintenance
The brake system is a matter of driving safety, so check the wear and tear of the brake pads and discs on a regular basis. Generally, brake pads need to be replaced when their thickness is less than 3mm. Also check the level and quality of brake fluid, which should be replaced every two years or 40,000 kilometres.

Air filter and air-conditioning filter
Air filters prevent impurities in the air from entering the engine and affecting performance. Generally, they should be replaced every 10,000 to 20,000 kilometres. The air conditioning filter affects the air quality inside the car and is recommended to be replaced every year or 10,000 kilometres.

V. Car cleaning
Regular cleaning of the car exterior and interior can not only maintain the beauty, but also prevent corrosion and odour. Body paint to avoid prolonged exposure to the sun, so as not to fade. Interior cleaning should pay attention to avoid the use of harsh chemical cleaners, so as not to damage the material.

VI. Precautions
1. Choose a regular car maintenance shop or 4S shop to ensure the use of genuine parts and professional service. 2.
2. Carry out maintenance in accordance with the manufacturer's maintenance cycle and projects, do not omit or delay.
3. Supervise the maintenance to prevent workers from cutting corners or operating improperly.
4. Keep the records and invoices of each maintenance for future enquiry and rights defence.

Car maintenance is something that every car owner should pay attention to, because proper maintenance can not only extend the life of the car, but also improve the performance and safety of the car, save repair costs and reduce breakdowns and accidents. So, what aspects of car maintenance should be noted? Below I will give you some common sense car maintenance and daily use of tips.

The common sense of car maintenance mainly includes the following aspects:
Regular inspection and replacement of fluid-like substances. Liquid-based substances are important for the operation of the car, including motor oil, transmission fluid, booster fluid, brake fluid, antifreeze and so on. These liquid substances have a certain service life and replacement cycle, if not replaced in time, it will lead to deterioration, pollution, oxidation and reduction of liquid substances, thus affecting the lubrication, cooling, braking, steering and other functions of the car. Therefore, vehicle owners should regularly check and replace the fluid-like substances according to the use of the vehicle and the manufacturer's recommendations to keep the fluid-like substances clean and sufficient. Generally speaking, engine oil and oil cartridge should be changed every 5,000 kilometres or 6 months, transmission fluid should be changed every 60,000 to 120,000 kilometres, booster fluid and brake fluid should be changed every 2 years or 40,000 kilometres, and antifreeze should be changed every 2 years or 40,000 kilometres.

Regularly check and replace cartridge substances. Filter elements are important parts of the car's filtration and purification, including air filters, air conditioning filters, petrol filters and so on. These filters have a certain filtration capacity and service life, if not replaced in time, will lead to filter blockage, breakage, failure, thus affecting the normal work of the car's air intake, air conditioning, fuel and other systems. Therefore, car owners should regularly check and replace the filter element according to the use of the vehicle and the manufacturer's recommendations to keep the filter element smooth and effective. Generally speaking, air and air conditioning filters should be replaced every 1 year or 10,000 km, and petrol filters should be replaced every 2 years or 50,000 km.
Regularly check and replace wearing parts such as spark plugs, brake pads and tyres. Wear parts are the parts that are most likely to wear out and be damaged during the use of the car, including spark plugs, brake pads, tyres and so on. These wearing parts have a certain service life and replacement cycle. If they are not replaced in time, it will lead to the decline in performance, failure and damage of the wearing parts, thus affecting the ignition, braking, driving and other functions of the car. Therefore, car owners should regularly check and replace the wearing parts according to the use of the vehicle and the manufacturer's recommendations to maintain the good condition and performance of the wearing parts. Generally speaking, the replacement cycle of spark plugs ranges from 30,000 to 120,000 km depending on the material, brake pads are usually replaced at around 30,000 km, and tyres are usually replaced at around 5 years or 80,000 km.
Regularly clean and maintain the paintwork, interior, air conditioning and other parts of the car. The paintwork, interior and air-conditioning parts of the car are an important reflection of the car's appearance and comfort, as well as its value and image. All these parts are affected by daily use and environmental factors, resulting in problems such as dirt, scratches, discolouration, mould and odour. Therefore, car owners should regularly clean and maintain the paintwork, interior, air-conditioning and other parts of the car according to the use of the vehicle and seasonal changes to keep the car clean and beautiful. Generally speaking, the paintwork of the car should be cleaned once a month, waxed once every six months and waxed once a year, the interior of the car should be cleaned once a month and once every six months, and the air conditioner of the car should be cleaned once a year.

Tips for car maintenance
In addition to the above common sense, car owners can also master some car maintenance tips to better protect and use their cars. Here are some tips for car maintenance:

For those who love cars, it is important to look at their cars and they take care of their maintenance. So what is the knowledge and maintenance intervals of the car in the maintenance process? Here we listen to Car e Total explain.

A day's maintenance content

(1) Signalling device check: turn on the ignition switch key (don't start the engine), check the lighting status of each alarm light and indicator light, start the engine to check whether each alarm light is closed normally, and whether the indicator light is bright still.

(2) Pass the appearance check: Before leaving the vehicle, check whether the vehicle and the lighting device are damaged, whether the vehicle is tilted, and whether there is oil leakage, etc.

Maintenance contents for one week

Tyre pressure check to adjust tyre pressure and clean up tyre debris. Don't forget to check the spare tyre.

Engine and various oilsCheck the fixed state of engine parts, check the surface of each engine joint for oil or water leaks; check and adjust belt tightness; check the fixing of pipes and wires in each part; check the oil replenishment; check and replenish the coolant; check and replenish the electrolyte; check and replenish the power steering fluid; clean the surface of the radiator; and add windscreen washer fluid.

Car maintenance is the key to ensure the normal operation of the car and extend the life of the vehicle, and car maintenance is not a complicated thing. You only need to understand the maintenance points of five oil, four filters and three water, you will be able to easily and correctly car maintenance. The following will introduce these points in detail, and give the corresponding replacement cycle, to help you better maintain your car.

Five oil maintenance points
1. Motor oil: Motor oil is an important lubricant to ensure the normal operation of the engine. According to different types of motor oil, the oil replacement cycle is different. Generally speaking, mineral oil needs to be changed when driving 5,000 kilometres or 6 months, semi-synthetic oil has a replacement cycle of 7,500 kilometres or 9 months, and fully synthetic oil has a replacement cycle of 10,000 kilometres or 12 months. Regular oil changes can effectively protect the engine and improve fuel economy.

2. Brake fluid: Brake fluid provides hydraulic pressure when the vehicle brakes to ensure the normal operation of the brake system. Brake fluid replacement intervals are generally 40,000 kilometres or 3 years. The quality and performance of brake fluid will deteriorate over time. If the brake fluid is not replaced for a long period of time, it may lead to brake failure, which will bring serious safety hazards.

3. Transmission fluid: Transmission fluid plays a lubricating role in the transmission to ensure the normal operation of the transmission. According to the use of the vehicle, the transmission fluid generally needs to be replaced once after 80,000 kilometres of driving. Timely replacement of transmission fluid can effectively protect the transmission and extend its service life.

Cars are made up of many parts that interact and rub against each other while driving, so lubricants are needed to help accomplish this. Maintenance is the process of replacing some of the lubrication, fastening, etc. that are worn out excessively or past their useful life so that the car can be kept in good working order. For example, there are a lot of fluids in a car that deteriorate in quality as the mileage rises and need to be changed regularly so that the breakdown rate can be reduced and the overall life of the car can be improved.

Oil and oil filters
It's safe to say that car maintenance is actually based on the life of the oil and oil filter. It is also the item we replace most frequently, according to the nature of the oil is different, mainly divided into mineral oil, full synthetic oil and semi-synthetic oil. The two types of oil have different maintenance intervals. Fully synthetic oils should be changed every year or 10,000 kilometres, semi-synthetic oils between 7,000 and 7,500 kilometres, and mineral oils at 5,000 kilometres. That's why some of our cars are serviced at 10,000 kilometres and some at 5,000 kilometres.

Air conditioning and air filters
These two filters are also consumable materials, equivalent to the filters in our air conditioners at home, and it is better to change them at two or three maintenance intervals. Some people do not replace it will not be very big damage, just the quality of air in the car and the air conditioning power consumption will be much higher, also not easy to cool. According to the specific environment of driving can be flexible to change, if the environment is very good three cycle change is also possible.

Spark plugs, transmission fluid, etc.
These are the core components of the car and play a very important role in driving. They are not easy to break down and will slowly deteriorate in quality as the mileage grows. Therefore, if they have not been replaced, it will take many times to start the car, which is actually a reminder that we need to replace them. Follow the instructions to carry out maintenance and replacement of these large parts can be, of course, the front of a cycle of maintenance will not be too big a problem.

Vehicle maintenance and repair
Vehicles are divided into daily maintenance and regular maintenance, the above mentioned are regular maintenance, daily maintenance is also very important. For example, we drive in time to check the state of the tyres, so that the engine compartment to keep clean, timely clean debris, are daily maintenance work. Maintaining proper tyre pressure can make travelling more comfortable, and replacing damaged tyres can also make travelling safer.

Precautions
Car maintenance is recommended to be carried out in a qualified 4S shop, or in a maintenance workshop you are familiar with. It is not recommended to complete in the unfamiliar shop, especially the oil maintenance, if the replacement of poor quality oil, will cause serious impact on the engine. Although it is cheaper, it is not worth it.

1. Check the oil level: Check the oil in your car regularly to ensure that the oil level is within the normal range. If the oil level is too low, you need to add or replace the oil in time.

2. Tyre pressure: Keeping tyre pressure within the standard range can improve fuel efficiency, reduce tyre wear and improve driving safety.

3. Brake system: Regularly check brake pads, brake discs and other components to ensure that the brake system is working properly.

4. Coolant: Check the coolant level and keep it within the normal range to prevent the engine from overheating.

5. Battery: Check the battery level and battery terminals regularly to keep the battery in good charging condition.

6. air filter: replace the air filter regularly to keep the engine air intake smooth.

7. Fuel filter: replace the fuel filter regularly to ensure the fuel system is clean.

8. Spark Plugs: Check the spark plugs regularly to keep the ignition system working properly.

9. drive belt: check the wear and tear of the drive belt and replace it in time if there is any abnormality.

10. Lubrication system: Check the fluid of the lubrication system, such as transmission fluid and steering booster fluid, regularly to keep the fluid within the normal range.

11. Vehicle Cleaning: Wash the vehicle regularly to keep its appearance tidy and prevent rust and corrosion.

12. Periodic Inspection: Regularly carry out comprehensive inspection and maintenance of the vehicle in accordance with the recommendations of the vehicle manufacturer.

As an important tool for our daily travelling, a car in good condition is not only a matter of driving safety, but also prolongs its service life. Here are some important notes for daily maintenance of the car, hope it can help you.

First, the appearance of clean

Regular cleaning of the vehicle is to maintain the appearance of the car neat and prevent corrosion of the key. In cleaning, should choose the appropriate cleaning agent, avoid the use of strong acid and alkali substances, so as not to damage the car paint. Also, pay attention to cleaning the wheels and hubs to prevent the accumulation of brake dust and road debris. For stains that are difficult to clean, do not forcefully wipe, so as not to scratch the surface of the car paint.

Second, tyre maintenance

Tyres are the only parts of the car that come into contact with the ground, and their condition directly affects driving safety and performance. Regularly check the air pressure of tyres to ensure that it meets the values recommended by the vehicle manufacturer. Insufficient air pressure will increase fuel consumption and tyre wear, while high air pressure will affect comfort and grip. In addition, check the depth of the tyre tread and replace the tyres when the tread wears to the limit mark. At the same time, pay attention to the balance and positioning of tyres to avoid run-out and abnormal wear.

Engine maintenance

The engine is the core component of the car, and regular replacement of oil and filters is the basis for keeping the engine running well. Follow the recommendations in the vehicle manual to choose the right oil type and replacement cycle. Also, check the engine cooling system to ensure that the coolant level and quality are normal. In addition, pay attention to the engine's belt and wiring harness, if aging, cracking or loose, should be replaced or adjusted in time.

Fourth, brake system check

Braking system is the key to ensure driving safety. Regularly check the wear and tear of brake pads and discs, and replace them in time when they are worn to the limit. At the same time, check the level and quality of brake fluid. Brake fluid is absorbent and long-term use will reduce braking performance, so it should be replaced according to the specified cycle. In addition, test the stroke and strength of the brake pedal, if there is any abnormality, troubleshooting should be carried out in time.

V. Electrical System Maintenance

The electrical system of the car includes the battery, generator, starter motor and other components. Regularly check the battery charge and the cleanliness of the electrodes to ensure that the battery is firmly connected. At the same time, pay attention to the working condition of the generator, if there is abnormal charging or insufficient power generation, it should be repaired in time. In addition, check the working condition of electrical equipment such as lights, windscreen wipers and horn to ensure their normal operation.

VI. Interior Cleaning and Maintenance

Keeping the interior of the car clean not only provides a comfortable driving environment, but also extends the service life of interior components. Clean the seats, carpets and dashboard regularly to avoid the accumulation of stains and dust. For leather seats, they should be cared for with specialised maintenance agents to prevent drying and aging. At the same time, pay attention to the ventilation of the car to prevent humidity and odour.

VII. Regular Maintenance and Inspection

In accordance with the maintenance cycle and items specified by the vehicle manufacturer, send the car to a professional repair shop for regular maintenance and inspection. Professional technicians are able to carry out comprehensive testing and maintenance of the vehicle, timely detection of potential problems and deal with them.

In short, the daily maintenance of the car is an important and meticulous work, we need to pay attention to all aspects of the details. Only by doing a good job of routine maintenance can we ensure that the car is always in good running condition, providing safety and convenience for our travelling.
