Insulation
INSULATIONInsulation is used as a sound-deadener to reduce exterior road and powertrain noises from the interior of the vehicle. Mastic insulators are also used as insulation. For information on the location of the mastic insulators, refer to Sound Proofing / Insulation. Insulation is installed:
- under the roof.
- above and below the instrument panel.
- at the cowl side panels.
- over the front and rear floor pans.
- inside the A-, B-, C- and D-pillar sections.
- behind the rear quarter trim panel.
- on the wheelhouse
Other forms of insulation include:
- front tunnel stiffening pad.
- dash panel stiffener.
- rear wheelhouse mastic pads.
It has heat-bondable mastic deadeners for improved noise, vibration and harshness (NVH) characteristics.
It also has sound dampeners located inside the D-pillar and plug holes in the rear quarter inner.
