Floor Pan Insulators Description

Floor pan insulators have been designed for the higher floor pan temperatures. Higher temperatures result from the use of the catalytic converter in the exhaust system. If you remove or disturb any insulators when servicing the vehicle in the field, reinstall the insulators in the original sequence and location. Use the material specified for that particular location on the floor pan if you replace an insulator.

• Floor pan insulator (cerra blanket thermal)

  Consists of 10 mm (3/8 in) thick aluminum silica (type 1).

• Floor pan insulator (amberlite)

  Consists of 10 mm (3/8 in) thick resinated fibers (type 2).

• Floor pan insulator sheet (phenolic bonded fiberglass) 305 x 457 mm (12 x 18 in) cut to size (type 3)

Types 1 and 2 have the following characteristics:

• Rolled stock
• Ordered by linear foot
• Cut to fit

When servicing or replacing interior insulators, observe the following instructions:

• Install the insulators in the original position and sequence. Place the pieces close together in order to avoid gapping or overlapping.
• Use the original part for the following reasons:
  • In order to determine the amount of replacement material required
  • As a template for cutting and fitting the new piece to the floor pan
• When installing the insulator, do not enlarge the cutouts or holes. The cutouts or holes are used for the attachment of the interior components such as seats or seat belts.
• Route the cross body harnesses for the following interior components over the floor pan insulators and into the original location:
  • The power seats
  • The lap belt warning light and alarm
  • The rear speakers

    Clip the cross body harnesses into place.

• Do not apply the spray-on deadeners and trim adhesive to the top of the floor pan at the area located directly over the catalytic converter or muffler(s).
