What are the solutions for the buzzing sound in Lavida's engine?

[VanMatthew]

Solutions for the buzzing sound in Lavida's engine are as follows: 1. The buzzing sound when accelerating may be due to a difference in quality between the new engine oil and the previously used one. Check the quality of the engine oil and replace it if necessary. 2. Another possible cause could be loose screws on the exhaust pipe or engine, or contact with the underbody shield. Tighten the screws properly. 3. If the buzzing sound occurs when accelerating and disappears when releasing the accelerator, identify the source of the sound. If it's on the right side of the engine, the issue might be with the generator's belt, the throttle valve, or the engine or other mounting brackets. If needed, take the car to a 4S shop for inspection and repair.

I've been driving my Lavida for a while and have encountered several instances of engine humming. Most of the time, it's due to issues with the engine mounts. When those rubber pads age, they amplify vibration noises, especially noticeable during acceleration. Another common cause is loose or worn belts, particularly noticeable during cold starts. The last time I encountered this, it was caused by a faulty tensioner pulley. If there's dirt on the fan or damaged blades, it can also produce a humming sound when rotating. Regularly cleaning the fan cover can help reduce noise. Additionally, a clogged air filter can restrict airflow, causing the engine to make similar sounds. Solutions include checking the mounts and replacing them promptly, inspecting the belt system for tightening or replacement, cleaning the fan blades, and replacing the air filter. If not addressed in time, accumulated vibrations can damage more components, potentially doubling repair costs. I recommend visiting a professional repair shop for a diagnosis first, avoiding DIY fixes to prevent accidents. In short, such issues should not be ignored as they relate to driving safety and comfort.

Solutions for Lavida Engine Humming Noise I often ponder over this issue. Start with simple checks like inspecting the engine mounts for integrity—replace them if the rubber is severely worn. Next, examine whether the belt is loose or cracked, then adjust the tension or replace the entire set. Clean any dirt from the fan blades, as foreign objects might be stuck inside. A clogged air filter can also cause humming; replacing it resolves intake issues. Sometimes, cooling system abnormalities produce humming noises, so check the pump and radiator connections. My personal habit is to stop and self-inspect upon detecting unusual sounds to avoid road hazards. If mounts and belts are fine but the problem persists, promptly visit a repair shop for professional diagnostics on the chassis or exhaust system using specialized tools. Remember, ignoring humming noises may lead to greater losses—don’t skimp on minor costs and risk major damage. Paying extra attention to these points during maintenance can prevent future issues.
