What is necessary and what is not necessary for car maintenance?

There is no doubt that the oil must be changed. Because the engine oil is called the "blood" of the engine, and the engine is the main concern and fatal point of the vehicle, if there is anything wrong with the engine, it will seriously affect the use of the vehicle. Engine oil mainly has the functions of lubrication, shock absorption and buffering, cooling and reducing engine wear. So one of the above functions is very serious.

Incidentally, it is a question that many car owners and friends often care about, whether their vehicles are suitable for all of synthetic engine oil or half of synthetic engine oil. For the choice of fully synthetic and semi-synthetic engine oil, you can add all synthetic engine oil according to your car habits, such as taking bad roads often or not driving often. If you drive frequently but the road conditions are good, you can add semi-synthesis, but of course it is not absolute. If you are diligent in maintenance, you can also add semi-synthesis. In synthetic engine oil, the replacement cycle is longer and the performance is better, depending on the owner's wishes. Mineral engine oil is not recommended!

Bian Xiaoshen knew that Bian Xiao's car had just been maintained, but the oil was not changed in time, which led to the quick drying of the oil during maintenance. If you pull the engine into the cylinder, it will make you want to cry, so you will not maintain the vehicle in time, and you must change the oil for maintenance according to the specified time.

2. Oil filter element

It is also necessary to replace the oil filter. Many car owners may find that when maintaining, especially when changing the oil, a round object should be replaced under the car, which is the machine filter. The filter element of the oil filter is used for filtering the oil, filtering out impurities such as dust, carbon deposit and metal particles in the oil, and protecting the engine. This is also one that must be replaced, and it is also a very important one.

3. Gasoline filter element

The gasoline filter will not be replaced frequently, of course, mainly according to the replacement cycle in different vehicle manuals, because the mileage or time for changing the oil filter in different vehicles is different. Of course, the mileage can also reach the manual or the time can be advanced or postponed, and there is no problem with ordinary vehicles. The gasoline filter element is mainly used to keep the engine (including the oil lubrication system and combustion chamber) clean and prevent the engine from being worn by cylinder pulling or dust.

4. Air conditioning filter element

If many car owners have no choice, they can only go to 4S shops or auto repair shops to carry out the above three kinds of minor maintenance, and the air conditioning filter can be replaced by themselves. As long as they pay attention for the first time, it is not difficult to replace it. Car owners friends buy one online and make it themselves, which can save a little labor cost. Of course, you can also buy it online, and ask the staff to help you replace it when doing maintenance. Especially the smell in the car. If it comes from the air inlet, it is recommended to replace it in time.

5, antifreeze

For most car owners, even if the car is scrapped or replaced, antifreeze may not need to be replaced, but special circumstances cannot be ruled out and attention should be paid to observation. Because there is something wrong with antifreeze, whether it is below the lowest line or above the highest line, it is generally observed. Its main functions are freezing prevention in winter, boiling prevention in summer, scale prevention and corrosion prevention.

6. Brake fluid

Open the engine cover and find a circle on the bracket, that is, add brake oil. Due to the water absorption characteristics of brake oil, after a period of use, oil and water are separated, and the boiling point is different, which reduces the performance and affects the braking effect. It is recommended to change the brake fluid every 40,000 kilometers. Of course, according to the situation of each car, the replacement cycle can also be shortened accordingly.

7. Steering power oil

Steering auxiliary oil is liquid oil used for automobile steering pump. We can easily turn the steering wheel by hydraulic action. Similar to automatic transmission oil, brake fluid and damping fluid. It is recommended to replace it during major maintenance.

8. Gasoline filter

Replace the gasoline filter according to the mileage in the vehicle manual. If there are many one-time maintenance items, they can be replaced later. In fact, many 4S shops or auto repair shops are conservative about the mileage of replacing gasoline filters, but it is also good to replace them carefully. So there is no need to replace it according to their requirements. To tell the truth, although the quality of gasoline is not good now, it is not that bad, especially for cars with high standard oil, there are not many impurities.

9.spark plug

The function of spark plug is self-evident. If there is no spark plug, it is like a car in a vegetative state. Once working for a long time, the engine will run unsteadily and the car will shake. In severe cases, the cylinder will be deformed and the engine will be more fuel efficient. So the function of spark plug is very important. Spark plugs can be replaced about 60 thousand kilometers. If the spark plug is often broken, it is recommended to sell the car in advance. Forget it.

10, transmission oil

There is no need to change the transmission oil in a hurry. Automatic transmission vehicles can be replaced in 80,000 kilometers, and manual transmission vehicles can be replaced in about 6.5438+0.2 million kilometers. Transmission oil mainly ensures the correct operation of the transmission and can prolong the life of the transmission. After changing the gearbox oil, the shift will feel smooth, preventing the gearbox from shaking, abnormal sound and gear jumping. In case of abnormal gear shifting, vibration and gear jumping, check the gearbox oil in time.

1 1, brake pads

There is no unified concept for the replacement of brake pads, especially for car owners who like to drive on the brakes or often use the brakes, they should always observe the brake pads. Especially when braking or braking, if you feel that the brakes are not strong, you should observe the problems of the brake pads in time. For vehicles, the importance of braking is not detailed.

12, battery

The battery replacement cycle is about 40,000 kilometers. If you don't drive for a long time and feel weak when you start the vehicle again, the battery may be broken. It is recommended not to turn on the headlights or play music or DVD in the car for a long time after the car is turned off. This will drain the battery. When you want to fire, you will find that there is not enough power to ignite. This is embarrassing.

13, tire replacement

Many car owners and friends, like Bian Xiao, don't know when to change tires. In fact, there are several common requirements for tire replacement: tire noise reduction replacement, wear replacement, and demand replacement. Of course, except for wear and tear replacement, the rest are based on the personal situation of the owner, and there is nothing wrong with it. Therefore, we focus on wear and tear replacement. There is a saying that it is recommended to replace the vehicle after reaching 6 years or more than 60,000 kilometers. However, it is not recommended to replace tires that are not frequently driven or have no worn tires. Tires have a long life, but they are not so fragile, so there is no problem in delaying replacement.

So the above are some common items in vehicle maintenance. From 1 to 13, the first few items are more important according to the importance of maintenance. Such as gasoline, mechanical filters, air filters, etc. , the rest can be replaced or maintained according to vehicle usage and vehicle performance. Vehicle maintenance is not necessary, but attention should be paid.
