What Causes the Loud Noise in Magotan?
3 Answers
When stepping on the accelerator, you may notice insufficient acceleration, lack of power, and a hysterical sound from the engine. Here are the detailed explanations: 1. Aging or loosening of engine mounts: Engine mounts are rubber blocks placed between the engine and the frame to reduce vibration and cushion the engine's operation, as well as to secure the engine. Once these mounts age or loosen, the engine will vibrate, and the faster the speed, the louder the vibration noise. Tighten or replace the engine mounts. 2. Improper use of engine oil quality: If the viscosity of the engine oil does not match the engine, it can easily lead to carbon buildup, causing the engine noise to increase. If the oil viscosity is too low, it will result in insufficient lubrication, wearing engine parts and creating abnormal noises. If the oil viscosity is too high, it will overload the engine, also producing noise. Use the oil grade specified in the vehicle manual and avoid mixing different brands of engine oil.
I've been driving a Magotan for several years, and the most common cause of increased noise is tire issues, especially after prolonged use when uneven wear occurs or driving on gravel roads, where the rolling sound of the wheels becomes particularly loud. Also, as the engine ages, if the oil hasn't been changed for too long or the oil passages are dirty and clogged, the engine will emit a buzzing roar. At high speeds, wind noise is also significant, and it feels like the window seals have aged and are letting in air. These noises can be distracting and make driving more fatiguing. I often test the sound sources on quiet stretches at night and have located the left front wheel as the noisiest spot. Regular checks on tire pressure and changing the engine oil can alleviate much of this. Another perspective is that in summer, higher temperatures cause parts to expand and increase friction, which can exacerbate the noise. Overlooking these small issues daily can accumulate into bigger problems.
As someone who enjoys tinkering with cars, I've found that the Magotan has numerous noise sources: the exhaust pipe may rust and loosen, causing increased roaring during acceleration; the suspension system's rubber bushings may age or the shock absorbers may fail, resulting in constant rattling over bumpy roads; worn brake discs can produce sharp, piercing squeals when braking. I use simple diagnostic tools like sound localization to identify noise points, starting with the chassis. Improvement methods include regularly replacing lubricating grease or installing soundproofing materials. Excessive carbon buildup inside the engine can also lead to incomplete combustion, increasing noise and affecting fuel efficiency. Long-term neglect leads to high maintenance costs and frustration, so I recommend starting with the easiest inspection points.
