How to check air filter on car？A comprehensive guide

The car air filter is a very important component in the car engine system. It is responsible for filtering impurities in the air entering the engine to protect the engine from wear and tear. Regular inspection and replacement of the air filter is essential to maintain engine performance and extend its service life.

1.Understand the location of the air filter

First, you need to know where the air filter is located in your car. Most modern cars have their air filters located in the engine compartment, near the side of the engine. Some models may have their air filters located on the side or bottom of the engine compartment. You can refer to your vehicle’s owner’s manual for the exact location.

2.Prepare tools

Before you begin your inspection, make sure you have the following tools:

Flashlight: for illuminating hard-to-see areas.

Screwdriver or wrench: for removing the air filter cover.

Clean cloth or compressed air: for cleaning the filter.

3.Check the air filter

Once you open the lid, you will see the air filter. The air filter is usually a pleated filter made of paper or cotton material. Take out the air filter and check its surface for obvious dust, dirt or debris. If the filter element looks very dirty, black or clogged, it means that it has failed and needs to be replaced.

Mild pollution:

If there is a small amount of dust or debris on the filter, you can gently tap the filter to shake off the dirt on the surface, or use an air pump to blow the dust out.

Severe pollution:

If the air filter is severely clogged, it is recommended to replace it directly with a new filter. In general, the replacement cycle of the air filter is every 10,000 to 15,000 kilometers, but it depends on the vehicle usage environment and driving habits.

4.Reinstall the air filter

After checking, if the air filter does not need to be replaced, you can put it back in place. Make sure the air filter is aligned correctly, then replace the cover of the air filter box and secure it.

5.Check the tightness

The last step is to check the tightness of the air filter box and make sure the cover is completely closed without any loose parts. If the air filter box is not completely sealed, it will affect the performance of the engine.

Conclusion

Regular inspection and replacement of the air filter is essential to maintain optimal engine performance. If the air filter is too dirty or clogged, it will not only increase the load on the engine, but may also cause reduced fuel efficiency and even damage certain engine components. Usually, you can check and replace the air filter yourself, but if you are unsure of the steps, it is recommended to ask a professional to handle it.
