The engine needs to suck in a lot of air during the working process. If the air is not filtered, the dust suspended in the air is sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder will cause serious "cylinder pull" phenomenon, which is especially serious in a dry and sandy working environment.

The way to change the car air filter is:
1. Open the inside of the glove box and you can see the support of the filter element. Pay attention to the yellow line on the left. If the support is blocked, remove it first;
2. There is a buckle at both ends of the filter element bracket, first pull the jam away, and the bracket can be pulled out with both hands. The left part of the filter element bracket is blocked by the special box, you have to move it to the right to pull out the support;
3. After taking it out, pay attention to the front and back. The method of putting it back is the same, but be careful not to insert it hard, the bracket is easy to deform. After changing the air conditioner filter element, change the air filter and open the engine compartment. This big box is the air filter, which is fixed by four screws;
4. Use a cross screwdriver to loosen and pull up to come out. Seeing that the air filter is white, it will turn black after a long time. If you do not replace the service station to help blow once during maintenance, the effect of the blown filter will be affected, and it is better to replace it with a new one;
5. After the filter element is taken out, pay attention to the front and back. It is recommended to replace the old with the new after comparing the front and the back. The new one is put back, usually there is a positioning, if it is put back upside down, there will be unevenness. After laying down, close the cover. When tightening, tighten it crosswise, first tighten it almost and then change to the opposite corner.
