Sound Proofing / Insulation: Description and Operation

Sound Deadeners and Insulators

WARNING: Before beginning any service procedure, refer to Safety Warnings. Failure to follow this instruction may result in serious personal injury.

NOTICE:
- Mastic is made of a combustible material and should be removed prior to carrying out welding procedures to the area. Heat zones from welding near the mastic can cause the mastic material to burn.
- Corrosion protection must be restored to the area after the mastic material is applied. Corrosion protection products may be wax based and loss of adhesion may occur.

NOTE:
- To restore the vehicle to design intent, missing or damaged sound deadeners and insulators should be installed with the correct service replacement component.
- The following illustrations serve as a reference to indicate mastic patch (butyl pad) and Noise, Vibration and Harshness (NVH) foam locations. Additional insulators and sound deadeners are used beyond those indicated in the illustrations.
