Replacing an engine air filter involves the following steps: 1. Open the engine hood and locate the air filter, which is generally positioned on the left side of the engine compartment, above the left front wheel. You will see a square black plastic box where the filter element is installed. 2. Remove the air filter element and check for excessive dust. Gently tap the end surface of the filter or use compressed air to clean the dust from the inside out. Do not rinse it with tap water. If the air filter is severely clogged, replace it with a new one. 3. After handling the air filter element, thoroughly clean the air filter box, as a large amount of dust often accumulates underneath, which can reduce engine performance. 4. When installing the new air filter, pay attention to a protruding plastic tab on the lower right side of the filter. This tab is designed to prevent incorrect installation. Ensure the plastic tab is securely inserted into the slot of the filter housing for proper installation.
Replacing the engine air filter is actually quite simple. I enjoy doing it myself—it saves money and keeps the car running smoothly. First, make sure the engine is cold to avoid burns. Then, pop the hood and locate the air filter housing, usually a square plastic box near the engine. Loosen the screws or clips, open the cover gently, and watch out for dust. Remove the old filter and clean any debris inside the housing with a vacuum or damp cloth. When installing the new filter, check the direction (usually marked with an airflow arrow) to avoid putting it in backward. Finally, secure the cover and tighten the screws. The whole process takes about 10 minutes. For optimal fuel efficiency and engine longevity, replace it every 12,000 miles.
I've been changing air filters for over 20 years, it's second nature to me. After parking and letting the engine cool, I check the filter location - usually in a visible spot under the hood. Just use a Phillips screwdriver to loosen the cover, but don't over-tighten to avoid cracking the plastic. Take out the old filter for inspection - replace immediately if heavily clogged. Clean the housing before inserting the new one, make sure the arrow direction matches, then snap the cover back. It's not expensive - a quality filter costs less than 50 yuan. Changing it annually greatly benefits the engine - smoother acceleration and reduced noise. This simple, time-saving procedure is a smart maintenance trick for your beloved car.
