The method for replacing the cabin air filter in a Cadillac ATSL mainly consists of the following steps: 1. Open the glove box. 2. Remove the central fixing screw on the upper wall of the glove box. 3. Pull out the upper box of the glove box. 4. At this point, the plastic cover of the cabin air filter becomes visible. 5. Unclip the four fasteners of the plastic cover to remove it. 6. After removing the cover, the cabin air filter can be seen. 7. Replace the filter and reinstall everything in reverse order. Below are the functions of the cabin air filter: 1. Ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. 2. Absorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and long-lasting moisture absorption. 3. Separates solid impurities such as dust, pollen, and abrasive particles from the air. 4. Maintains clean cabin air to prevent bacterial growth, creating a healthy environment; effectively separates solid impurities like dust, pollen, and abrasive particles from the air; efficiently blocks pollen to ensure passengers do not experience allergic reactions that could affect driving safety. 5. Prevents car windows from fogging up, ensuring clear visibility for safe driving; provides fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety; effectively sterilizes and deodorizes.
I've changed the ATS-L cabin air filter several times myself and find it super easy. Just get a new filter online for around 20-30 yuan. First, open the glove compartment on the passenger side—clear out any items inside and don't forget to lock the car key. Then locate the clips on either side or at the bottom of the glove box; a gentle press will release it. Behind it, you'll see the filter housing cover, usually a plastic piece—push or slide it open. The old filter might be dirty, so just pull it out and toss it. When installing the new one, pay attention to the arrow direction; align it with the airflow arrow (usually facing the rear of the car). Snap the cover back on and reattach the glove box. The whole process takes about 10 minutes max, no tools needed. Replace it every spring and fall for fresh cabin air and savings. I recommend doing this on a sunny afternoon to avoid dust getting inside.
I'm quite familiar with replacing the ATS-L's cabin air filter. The key to this task lies in being meticulous to avoid damaging anything. Start by removing the glove box—most models have clips or screws securing it, which can be gently released to take it down. Then locate the filter cover behind it, open it up, and remove the old filter. When installing the new filter, pay close attention to the airflow arrow direction; getting it wrong will affect the AC performance. I always double-check the arrow during DIY to ensure it's facing the right way. Opting for a dust-resistant filter material can extend its lifespan by a few months. Replace it every 6 months or 10,000 km to prevent odors and protect the AC system. Cost-wise, DIY is much cheaper, as dealership labor fees aren't worth it. Keep the car well-ventilated during maintenance to minimize dust. Safety first—always operate with the engine off. A few practices, and you'll master it effortlessly.
