Open the hood, remove the air filter cover, and directly replace it with a new air filter. More information about air filters is as follows: Location of the car air filter: The air filter, fully named as air filter element, is located on the side of the engine under the hood. Some air filters are cylindrical in shape, also known as air filter cartridges. Function of the car air filter: It is used to filter the air entering the engine, removing dust particles from the air, providing clean air for the engine combustion chamber, with the main purpose of protecting the engine. Replacement interval: Generally, a car air filter should be replaced every 15,000 kilometers. For vehicles frequently operating in harsh environments, it should be replaced no more than every 10,000 kilometers.
I always find it quite simple to change the car's air filter. It's located inside the black box in the engine compartment. Make sure the car is parked and turned off, and the engine has cooled down before operating. First, open the hood and locate the box connected to the intake pipe, usually secured by a few screws or clips—use a screwdriver to loosen them. Remove the old filter and check it; it's definitely covered in dust, affecting the airflow. Before discarding it, wipe the inside of the box clean to avoid residual dust. After taking out the new filter, pay attention to the directional arrow to avoid installing it backward, then reassemble and tighten the screws. Generally, it should be replaced every 10,000 kilometers or every six months, but more frequently in dusty areas. Doing it yourself is cost-effective—buying a matching filter costs just a few dollars, and it can improve engine efficiency and reduce fuel consumption. Remember to start the car after replacement and listen for any unusual noises to confirm everything is fine. DIY is fun and helps maintain the car well.
I've been driving for years, and changing the air filter is part of routine maintenance—it doesn't take long to get done. The steps are: park the car and turn off the engine, wait for it to cool, then open the hood and locate the filter housing—it's the part connected to the thick intake pipe. Release the clips or unscrew the bolts to remove the old filter, which will clearly look dirty and clogged compared to the new one. Wipe the inside of the housing with a cloth, and when installing the new filter, make sure the orientation is correct. It's best to replace it every 15,000 kilometers; delaying the replacement can cause poor engine airflow, increased fuel consumption, and sluggish acceleration. Doing it yourself saves money—the filter costs around 20 yuan, while dealerships charge over 100. Choose a reputable brand to avoid leaks. The key point is that it affects engine lifespan and cleanliness, so regular maintenance keeps things worry-free, and driving feels smoother and more stable.
I just learned how to change the air filter and found it quite easy to get started. Park the car, turn off the engine, and let it cool down. Open the hood and locate the plastic box. Remove the cover, take out the old filter and discard it. Wipe the box clean and place the new filter in the correct position, making sure not to install it backwards. Tighten the cover and start the car to confirm everything is working properly. Just change it every 20,000 kilometers—doing it yourself saves time, hassle, and is quick to get done.
