Mastering four major maintenance projects.

Mastering four major maintenance projects.

The importance of car maintenance, car riders must be very clear. Unless they are louts, car maintenance is a very important thing for car owners. However, there is specialization in the art, and thinking and doing are two different things. Even a small number of riders only know that maintenance is to change the oil. As for the rest, they only know when the car has problems to be repaired.

Many drivers think that car maintenance is a very troublesome thing, but it is not. Today we will talk about four very simple and practical maintenance projects.

1. Oil filter element

The oil filter is like our water purifier, which prevents impurities in the oil from entering the engine, thus ensuring that the friction of the engine is aggravated by impurities and prolonging the life of the engine.

How often do you change the oil filter? The replacement time of the oil filter depends on the oil added. Generally speaking, mineral oil should be replaced after running for 3000 kilometers. If it cannot be replaced in time due to special reasons, it must be replaced when it is no longer than 4000 kilometers.

Similarly, the semi-synthetic engine oil should be replaced within 5,000-6,000 kilometers. In addition, mineral oil and semi-synthetic engine oil must be replaced after half a year, even if the mileage is not that much, because there is a shelf life. The mileage and time for changing to synthetic engine oil is slightly longer, 8000- 10000 km or 8 months.

2. Air filter element

As the name implies, it blocks impurities in the air, such as leaves, sand and any other fine particles, and provides pure air for the engine.

Generally speaking, the air filter element should be replaced every time a car undergoes major maintenance (every 65,438+0,000 kilometers). However, the condition of the air filter depends on the vehicle environment. For cities with better environment, it is not a problem to use 1 10,000 kilometers; If there is too much dust, it will have to be reduced to 8000 kilometers. If there is too much dust in the north, it is recommended to replace it every 5000 kilometers.

3. antifreeze

As one of the most important liquids in automobiles, antifreeze plays a role in cooling and radiating the engine and ensures the normal operation of the engine. If there is too little antifreeze or there is something wrong with the quality, the heat of the engine will not be discharged in time.

In the long run, the engine will be damaged. Most parking lots are recommended to be replaced every 2 years or 40,000 kilometers. In addition, we also need to ensure that the car has sufficient antifreeze; Because antifreeze will be consumed,

If it is found that the liquid level of antifreeze is close to or lower than the minimum scale, it is necessary to replenish antifreeze in time. Remember to add antifreeze of the same product. If the antifreeze is too small to be replaced in time, purified water can be added instead, but only for short-term emergency use; Then send it to repair in time.

4. Brake fluid

Brake oil is very important for parking without braking. Generally speaking, change the brake oil every 30,000-50,000 kilometers or 2 years. In the process of automobile use, brake oil can contact with moisture and impurities in the air through the vent hole of the oil storage pot, which will reduce the boiling point of brake oil over time.

After the boiling point is lowered, if the brake is used for a long time, the temperature of the brake oil will rise rapidly, and the brake oil will easily produce air resistance after boiling, which will lead to the decrease of braking force and even the failure of the brake, resulting in safety accidents.

Summary: After reading these four items, do you find that except for brake oil, the other three items have a feeling that they can be done by hand, and the knowledge of automobile maintenance has increased!
