Symptoms of water entering the air filter: The engine may experience poor acceleration, sluggishness, and insufficient fuel supply. If the situation is severe enough that water enters the cylinders, the engine may exhibit piston knocking during operation, thereby accelerating engine wear. If water is found in the air filter, do not start the engine. Promptly wipe off any rainwater on the engine and check the generator belt for cracks to avoid shortening the vehicle's lifespan. Steps to replace the air filter: 1. Loosen the filter lock and remove the fixing nut; 2. After removing the cover, the air filter element will be visible. If dirt is found inside or outside the filter housing, wipe it clean with a cloth first; 3. Then, you can replace the new filter element, but be careful not to touch the paper part of the filter with your hands, especially avoiding contamination by oil.
When the cabin air filter gets wet, you'll notice a musty or rotten odor in the car, especially when the AC is on—it feels like the dampness of staying in a basement for too long. The airflow becomes noticeably weaker, blowing out moist air that significantly reduces cooling efficiency. In summer, driving feels like being in a steamer. Sometimes, you might hear dripping sounds or spot water stains near the dashboard or AC vents. The high humidity can also cause fogging inside the windows or even mold growth on seats. Over time, bacteria and mold multiply, posing respiratory health risks like triggering coughs or allergies. It's recommended to promptly check if the AC drain hole is clogged or if there's an issue with the parking spot. Best to visit a repair shop immediately to replace the filter and clean the entire AC system, preventing minor issues from turning into major headaches.
