What should I do if the Nissan Teana engine is too noisy?

Reasons for excessive engine noise in Nissan Teana: 1. Excessive carbon buildup in the engine. 2. Improper use of engine oil or dirty engine oil. 3. Loose screws on the engine underguard. Tighten or adjust the screws on the engine underguard. 4. Aging engine mount pads. The mount pads support the engine and can only be replaced when aged. 5. Loose plastic parts in the engine compartment, such as the engine cover or intake pipe, which can be tightened. 6. Abnormal noise from the engine belt, including the power steering belt and alternator belt. Aging, overly loose, or overly tight belts can cause noise and should be replaced or adjusted. 7. Engine knocking. This can be caused by excessive carbon buildup inside the engine or the use of substandard fuel, requiring carbon cleaning and fuel replacement.
Speaking of the Nissan Teana's engine noise issue, I've personally dealt with many cases. First and foremost, checking the engine oil is crucial. If the oil level is low or deteriorated, increased engine friction can cause a buzzing sound. Quickly check the dipstick to see if it's low or dirty, and change the oil promptly if needed. Next, listen to the source of the noise. If it's a squealing sound, it might be due to loose or worn belts. The Teana's belt system often develops issues after over 100,000 kilometers, requiring a new belt and proper tension adjustment. Also, inspect the engine mounts. When the rubber deteriorates, vibrations transfer to the body, increasing noise. Check for cracks in the mounts. Exhaust system gasket leaks can also add to the noise. If you can't resolve it yourself, I recommend a comprehensive diagnosis at a Nissan dealership. Don't ignore the issue—excessive noise indicates potential wear and tear. Safety comes first.
