What to do if the sound insulation cotton under the chassis of the 10th-generation Civic falls off?
2 Answers
The sound insulation cotton under the chassis of the 10th-generation Civic can be reattached using glue or silicone sealant. The car chassis consists of four parts: the transmission system, the running gear, the steering system, and the braking system. Installing sound insulation under the car chassis provides comprehensive functions such as high adhesion, high wear resistance, impact resistance, rust prevention, corrosion resistance, and noise reduction. Additional information: Here are the specific functions of car chassis sound insulation: 1. Reduce road noise: Car chassis sound insulation mainly targets the road noise generated by the friction between the tires and the ground, which can significantly reduce the road noise caused by the friction between the tires and the ground, greatly enhancing the driving safety for the owner. 2. Absorb vibrations and block heat: Applying vibration-damping strips and sound insulation cotton under the car chassis will effectively absorb any vibrations and block heat.
I've been driving a tenth-generation Civic for several years. Last time, a large piece of the underbody sound insulation suddenly fell off, causing an immediate buzzing noise that made driving really annoying. This material mainly absorbs vibrations and prevents stone chips. After it fell off, not only did it affect driving comfort, but it could also lead to underbody rust. I pulled over to check and found that the installation adhesive had aged and cracked. Since nearby repair shops didn’t have matching parts, I temporarily fixed it with strong double-sided tape and continued driving. The next day, I went to the dealership for a proper fix. The mechanic said this generation of Civic’s underbody design tends to trap water stains, weakening the adhesive over time. They replaced it with an OEM sound insulation mat, costing a few hundred bucks to resolve. Usually, when washing the car, it’s important to regularly check the underbody corners—don’t wait until a major issue arises.
