Insulation is used as a sound absorber to reduce road and driveline noise from entering the passenger compartment. Mastic insulators are also used as insulation. Insulation is installed:

• under the roof.
• above and below the instrument panel.
• on the hood side panels.
• above the front and rear floor panels.
• inside the center, center and D-pillar sections.
• on the cowl/quarter panel.
• behind the rear quarter trim panel.

Other forms of insulation include:

• front tunnel stiffener pad.
• instrument panel reinforcement.
• mastic pads on the rear wheel arch.
• mastic pads on the rear doors.

It has heat-bonded mastic dampers to improve NVH performance.

It also has dampers located inside the D-pillar and plug holes in the inner rear quarter.

Body Sealer Types and Applications

Seam Sealer

• thick, non-sagging adhesive/sealer used for cosmetic seams, truck body seams, and door skin and floor seams.
• can be used for water leaks and noise concerns.

Silicone Gasket and Sealer

• formed-in-place gasket and multi-purpose adhesive/sealer.
• room-temperature-vulcanizing silicone rubber.

Silicone Aerosol Lubricant

• makes door and window weatherstrip flexible and soft.
• makes door closing easier.
• slows weatherstrip squeaks.
• slows weatherstrip wear.
• helps maintain door glass alignment by reducing friction between the glass run and rubber weatherstrip.
• do not use before painting.

Trim and Weatherstrip Adhesive

• fast-drying, strong adhesive designed to bond weatherstrip to all body panels and surrounding metal.
