Will Replacing Soundproofing Cotton Damage the Car?

[AliceDella]

Replacing soundproofing cotton will not damage the car. Methods for car soundproofing include: 1. Applying sound-absorbing foam material under the engine hood; 2. Installing soundproofing cotton material in the trunk, at the bottom of the trunk, and on the wheel arches on both sides of the trunk; 3. Installing sealing strips inside the doors; 4. Installing professional damping plates in areas prone to noise; 5. Installing sound-deadening pads and moisture-proof soundproofing cotton on the central chassis and rear trunk chassis of the cabin; 6. Adding soundproofing cotton throughout the car body; 7. Replacing tires with better noise reduction performance. The causes of car noise are: 1. Carbon buildup in the engine; 2. Damaged shock absorbers; 3. Large gaps in the cab or vehicle body; 4. Aging tires; 5. Internal damage to the valve guides; 6. Cooling system failure; 7. Poor-quality engine oil; 8. Engine misfire; 9. Carbon buildup on spark plugs.
