7 routine maintenance items for cars

Regarding the maintenance items and cycle of the car, I believe that most car owners do not know very well, and it is estimated that everyone will be handled by the 4S shop.

In fact, when driving, car owners and friends should pay more attention to the warning signs on the dashboard, and also pay attention to the maintenance items and maintenance cycles of the car, such as oil, machine filter, air filter, air filter, spark plug, etc. Take care of our car carefully so that it can work better for us and increase its service life.

Let's talk about what maintenance items should be done in each maintenance cycle and some precautions.

Note: Since the maintenance items or maintenance time of each model are different, the maintenance time recommended by the manufacturer or 4S shop shall prevail.

1. Oil and oil filter

Maintenance cycle: every 5000 kilometers or so

Under normal circumstances, the first guarantee is carried out at 5000 kilometers or 6 months (whichever comes first), and then the vehicle is maintained every 5000 kilometers or 6 months. Of course, the maintenance time or mileage of models of different brands are not the same. You can refer to the maintenance time recommended by the manufacturer or 4S shop.

2. Air filter

Maintenance cycle: every 20,000 kilometers

The air filter plays a role in filtering out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder. However, after a period of use of the air filter, dust will stick to the filter element, so corresponding maintenance and replacement must be carried out, otherwise the filtering capacity will be reduced, the air circulation will also be hindered, and the engine will not work normally. Therefore, regular maintenance of the air filter is also crucial.

3. Air conditioning filter

Maintenance cycle: every 20,000 kilometers

The air conditioning filter plays a vital role in the air filtration in the car. It can filter out pollen, soot, benzene, methanol, PM2.5, tiny organisms and other inhalable tiny particles, keep the air in the car clean, and give it to the car. Passengers provide a good air environment.

Precautions:

Ordinary air-conditioning filters can only inhibit the entry of dust and particles, while the activated carbon series air-conditioning filters can use the physical properties of activated carbon itself to absorb other tiny organisms and more harmful substances in the air, so it is recommended to use Air-conditioning filter of the activated carbon series.

4. Spark plug

Maintenance cycle: every 30,000 kilometers

Long-term use of the flower plug will cause carbon deposits, which will cause insufficient engine combustion and difficulty in starting. Therefore, the vehicle needs to replace the spark plug regularly to maintain the best running state of the engine.

Precautions:

There are many spark plug brands on the market, and there are many different brands. It is recommended to use platinum or iridium spark plugs. Its characteristic is to make the engine start faster and save a certain amount of fuel consumption.

5. Brake fluid

Maintenance cycle: every 30,000 kilometers

Brake fluid, also known as brake fluid, is an indispensable part of the braking system. Frequent braking during driving generates a lot of frictional heat, which increases the temperature of the braking system. If a brake fluid with a low boiling point and easy to evaporate is used, the brake fluid will evaporate at high temperatures, and the pipes of the local brake system are filled with steam. , Resulting in air lock, causing brake failure.

Precautions:

Try to buy at qualified large-scale sales places to prevent counterfeit and inferior products; it is best to use professional equipment to replace them, so that they can be more thorough without residual impurities and avoid air resistance.

6. Gasoline filter

Maintenance cycle: every 60,000 kilometers

The function of the gasoline filter is to filter out the iron oxide, dust and other solid impurities or moisture contained in the gasoline to ensure that the clean gasoline enters the engine for full combustion. If the gasoline filter is too dirty or clogged, it will cause insufficient engine power and difficulty in starting. At this time, the oil filter should be replaced in time to extend the service life of the engine.

Precautions:

The gasoline filter is an important component of the electronic fuel injection system. Only the original matching or higher quality gasoline filter can provide the clean fuel required by the electronic fuel injection system, so as to optimize the engine performance, so everyone chooses the gasoline filter Pay attention to this when cleaning the instrument.

7. Transmission oil

Maintenance cycle: every 60,000 kilometers

Gearbox oil is an oil product that keeps the gearshift system clean. It can ensure the normal operation of the gearbox and extend the life of the transmission device. It can also provide effective lubrication at low temperatures and reduce oil loss.

Precautions:

When changing the oil, it is necessary to replace the automatic gearbox oil specified by the manufacturer. This is because different automatic gearboxes have different internal structures, friction parts and sealing parts. The original oil is based on the structure and material of the gearbox. The formulated oils of other brands may not be suitable even if they are of good quality.

In addition, many current models use electronic power assistance, so there is no need to change the steering power oil. If it is mechanically assisted, it will be carried out at 60,000 kilometers.
