What to Do When the Sound Insulation Cotton Under the Civic Chassis Falls Off?
2 Answers
Solutions for the sound insulation cotton under the Civic chassis falling off: 1. Use glue or silicone to stick it back. 2. Take it to a repair shop for treatment. Additional information: Installing sound insulation under the car chassis has the following benefits: 1. Reduces road noise: The sound insulation under the car chassis mainly targets the road noise generated by the friction between the tires and the ground, significantly reducing the noise and greatly improving driving safety for the owner. 2. Absorbs vibrations and blocks heat: Applying vibration-damping strips and sound insulation cotton under the chassis effectively absorbs any vibrations and blocks heat. 3. Isolates low-frequency noise and reduces heat conduction: The construction under the chassis focuses on solving noise from the engine and road, not only efficiently isolating low-frequency noise but also greatly reducing the conduction of heat from the engine and exhaust pipe into the cabin.
I've been repairing cars for several years, and my own Civic has also experienced sound insulation cotton detachment issues, usually caused by chassis vibration or adhesive aging. You can handle it yourself first: find a safe environment to jack up the car or park it on level ground, and wear gloves to protect your hands. Use an alcohol cleaner to thoroughly wipe the area where the cotton fell off the chassis, ensuring there is no grease. Then go to an auto parts store to buy specialized sound insulation cotton and automotive adhesive—don't use regular glue as it won't stick. After cleaning, wait for the surface to dry completely, evenly apply the adhesive to the new cotton, and gently press it into place for a few minutes. The whole process takes about 30 minutes. While you're at it, check if the surrounding sound insulation materials are loose and reinforce them in time. After completion, test drive to see if the noise decreases—that means success. Regularly inspect during maintenance to prevent issues. DIY saves a few hundred dollars and hones your skills, but be careful not to scratch the car paint or injure yourself.
