Why is the Outlander engine noisy?
2 Answers
The reasons for the loud engine noise in the Outlander are as follows: Engine produces a "popping" sound: The unpleasant engine noise is most likely caused by the engine being either overheated or too cold, and there is also a high probability of insufficient oil. Engine overheating leading to loss of power: If the engine operates for an extended period, causing the surface to overheat, the cooling system may fail. The first step in this situation is to check the cooling system. If there is an issue with the cooling system, it could lead to exhaust blockage, as the vacuum tube might be broken. At this point, steam or hot air may escape from the engine, producing a "hissing" sound.
I've been driving the Outlander for several years and think the loud engine noise might be related to daily usage. The Outlander itself is an SUV, so its engine naturally makes slightly more noise than sedans. However, if there's abnormal roaring or humming, you should pay attention. Common causes include aged or unsuitable engine oil leading to insufficient lubrication and increased internal friction. In such cases, I usually first check the dipstick to see the oil level and whether it's dirty. Also, a loose or worn-out belt can produce a screeching noise, especially during acceleration—I replaced the belt myself, and the problem was mostly resolved. Additionally, a clogged intake system can make the engine work harder and sound louder. I recommend regularly cleaning the air filter. If you're not familiar with these checks, at least inspect the engine oil and visit a repair shop if necessary to prevent minor issues from escalating into damaged components.
