Hello everyone, this is a column focusing on car repair and maintenance. There are car mysteries you don’t know, and it will teach you how to avoid the big pits on the road of car ownership. I believe that not only you but also many people have a certain sense of obscurity about the car aftermarket, which will help you uncover the unknown stories of car repair and maintenance.
Many people will encounter a multiple choice question when maintaining a car, that is, whether it is necessary to replace the filter element above when maintaining the car. A lot of people around here have different opinions, which makes it difficult for car owners. In this issue, the editor will take you to know when the filter element on the car should be replaced!
There are the following common filter elements in automobiles, which are oil filter, gasoline filter, gearbox oil filter, air filter and air conditioning filter.
Oil filter element
The oil filter element is used to filter engine oil, which is of great significance. Under the long-term operation of the engine, the iron filings will be worn between the various parts, and the oil itself will gradually produce glue, so the oil filter element has appeared to help recover these dirt and maintain a certain degree of cleanliness inside the engine.
This kind of external filter element is relatively common, and most models are in use.
It is absolutely wrong to say that the oil filter element does not need to be changed every time it is maintained. The oil has been replaced, and if the oil filter element is old, the impurities collected inside the filter element will re-enter the engine with the new oil, then the new oil will be replaced for nothing.
Although the service life of the oil filter element is very long, which has far exceeded the service life of the oil, it does not mean that the oil filter element can be used many times.
The editor suggests that the oil filter element must be changed every time the oil is changed.
Oil filter element of second gearbox
Take the gearbox of Zaifu as an example, the gearbox oil filter element and the oil pan are integrated together. Although there is a magnet to assist the adsorption of sludge, it still can not stop the filter element from getting dirty.
Clear mud can be seen everywhere on the iron absorber, and you can imagine how much mud there is inside the filter element.
The automatic gearbox is a very sophisticated assembly and is very sensitive to sludge and impurities. If the new oil is changed, the filter element is not changed, and the sludge accumulates more and more, which is very likely to damage the gearbox.
The editor suggests: every time you change the transmission oil, you need to change the filter element.
Three gasoline filter elements
Gasoline filter element is used to filter impurities in gasoline, there are built-in and external two types. The service life of the built-in gasoline filter element is very long, basically about 100000 kilometers. The external one is relatively short, usually about 10, 000 to 20, 000 kilometers.
Gasoline filter element has a great impact on the engine, the accumulation of impurities will block the oil road, will cause the engine power decline, jitter and even flameout.
Editor’s suggestion: the replacement cycle set by each manufacturer is different, please strictly refer to the maintenance manual and replace it regularly.
Four air filter element
The function of the air filter element is to filter the air into the engine, the dirty filter element will affect the air intake efficiency, resulting in insufficient air intake, and the power will decline when the engine is running at high speed.
The editor suggests that there is no absolute replacement cycle for the air filter element, and the air quality has a great influence on the filter element. If you often drive in the suburbs, you can change the air filter element every two times. If the air quality is not good, it is recommended to change the air filter element every time the oil is changed. Of course, if the air quality is very poor, it should be checked regularly.
Five air conditioner filter element
The air filter element filters the air in the car, so the cleanliness of the air filter element has the most direct effect on the health of the passengers.
Editor suggested: every quarter to check the air conditioning filter element, as long as there is an obvious color change, the existence of visible down and dust, it is necessary to replace.
Many people care more about cars, use all-synthetic oil and drive carefully, but they are often ignored in air-conditioning filters. If the car breaks down, it can be repaired, but there are some diseases that can’t be cured if you get sick in life. The attribute of a car is to serve people, not important people to serve the car.
On the whole, it seems that the existence of each filter element is of great significance and can never be replaced. And individual filter elements have strict replacement cycle restrictions. Now, as the owner of a car, do you know more about how to raise a car?
