The owner's family car knowledge】There are many benefits of regular car maintenance. Not only can the service life of the car be prolonged, but it is also beneficial to the health of the human body. Especially when the season changes, maintenance is even more important to the operation of the car. In this article, let’s take a closer look at a few items that require regular maintenance.

1. Wiper blade

The life span of the wiper blade varies according to its own quality and use environment. Usually, the life span ranges from 2 to 4 years. Of course, the details still depend on the use of the wiper. If the surface is deformed under pressure or scratched by a hard object, it needs to be replaced in time. In addition, the car owner had better spray a little liquid glass with good lubricity before using the wiper to avoid "dry scraping" of the wiper blade. When purchasing a wiper blade, the car owner can touch the surface of the rubber wiper blade with his fingers. If the blade is found to be aged, hardened, cracked, and the rubber blade is not elastic, it can be judged as a fake product.

2. Engine lubricating oil

Under normal circumstances, the manufacturers of naturally aspirated engine models sold in China will require users to change the lubricating oil when driving 5000 km-15,000 kilometers, while the supercharged engine models require replacement when driving 5000 kilometers. If the car does not drive too much Or it has been stopped, it is best to change the oil every six months. Of course, if your environment and oil quality are good, you can appropriately extend the oil change interval and time.

3. Oil filter element

The function of the oil filter is to filter out debris, colloids and moisture in the oil, so it must be replaced with the oil. If it is not replaced, the oil will not be filtered, which will cause the internal parts of the engine to wear out due to the impurities in the oil.

4. Air filter element

If the filter element is severely blocked, the air intake resistance will increase and the engine power will decrease. At the same time, due to the increase in air resistance, the amount of gasoline sucked in will also increase, resulting in an excessively rich mixture ratio, which will worsen the engine's operating state, increase fuel consumption, and easily produce carbon deposits. Usually, you should get into the habit of checking the air filter element frequently.

5. Brake fluid

Brake fluid is a liquid medium that transmits brake pressure in a hydraulic brake system of an automobile, and is used in vehicles that use a hydraulic brake system. Because the brake hydraulic system must allow the brake fluid to communicate with the atmosphere in order to operate normally, and long-term operation will cause the brake fluid to absorb water and turn into bubbles at high temperatures, resulting in a decrease in brake performance. Therefore, for safety, the car should mainly check the brake fluid regularly and replace it on time.

Experts recommend replacing it every two years or when driving 50,000 kilometers. It should be noted that different types and brands of brake fluids should not be mixed, otherwise the braking efficiency will be reduced.

6. Brake pads

According to different personal driving habits, the service life of the brake pads is also different. However, it is best for car owners to check the brake pads of the vehicle at about 20,000 kilometers and replace the brake pads at about 30,000 kilometers. Usually, car owners can check the brake pads by touching the tire wall with their hands after parking. If the temperature of a tire wall is particularly high, it is likely that there is a problem with the brake pads. The owner should go to the 4s shop to check the brake pads immediately. Check.

7. Antifreeze

The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block or cover when the vehicle is stopped in cold winter. But we have to correct a misunderstanding, antifreeze is not only used in winter, it should be used throughout the year.

If the antifreeze fluid is not changed for a long time, its anti-corrosion, anti-rust and anti-scaling functions will be reduced, which will cause the cooling system to malfunction or even rust. Under normal circumstances, the antifreeze is generally replaced every 1.5 to 2 years.
