How to Solve Excessive Car Noise?
2 Answers
Solutions for excessive car noise are as follows: 1. Loose belt tension. When the engine belt tension is insufficient, the engine will produce a sharp squealing noise during operation, severely affecting the driver's experience. Solution: Adjust the tension of the engine belt. 2. Incorrect engine oil condition. Solution: Replace the engine oil. 3. Leakage in the intake or exhaust pipe. When there is a leak in the intake or exhaust pipe, starting the engine will cause gas to escape from the leak during intake and exhaust, creating vibrations and noise. Solution: Inspect the intake and exhaust pipes and replace them if necessary. 4. Poor fuel quality. When using low-quality fuel, combustion inside the engine deteriorates, causing severe vibrations and noise. Solution: Replace with higher-quality fuel with a higher octane rating. 5. Abnormal engine noise. Loose screws on the engine underguard can prevent the engine from being securely fixed, leading to severe shaking and noise during operation. Solution: Tighten or adjust the screws on the engine underguard.
When the car noise is loud, I recommend first identifying the source of the noise before taking targeted measures. Engine noise is the most common issue; for example, loose engine mounts or old engine oil can amplify the machine sound. Check if the oil needs changing or switch to a high-quality synthetic oil. Exhaust pipe damage is also frequent, with rusted joints or holes causing a rumbling noise; you can tighten the bolts yourself or visit a professional shop for welding. Tire noise becomes noticeable at high speeds, where uneven tread wear or mismatched tire pressure can make road noise harsh; opt for quiet tires like the Michelin Primacy series or regularly adjust the tire pressure to the standard value. Wind noise is often caused by aging window seals, leading to annoying whistling sounds while driving; purchasing new seals and applying them can solve the issue in just a few minutes. Also, pay attention to loose body parts like door locks, which can produce squeaky sounds—simply apply lubricant or tighten them. Don’t overlook these small issues, as excessive noise not only affects driving comfort but may also accelerate fatigue and lead to accidents. It’s advisable to inspect key points monthly or get a comprehensive diagnosis at a repair shop once in a while.
