REPAIRING MATERIAL
Foam RepairINFOID:0000000006248486
During factory body assembly, foam insulators are installed in certain body panels and locations around the
vehicle. Use the following procedure(s) to r eplace any factory-installed foam insulators.
URETHANE FOAM APPLICATIONS
Use commercially available Urethane foam for sealant (foam material) repair of material used on vehicle.
Read instructions on product for fill procedures.
Example of foaming agent filling operation procedure
1. Fill procedures after installation of service part.
a. Eliminate foam material remaining on vehicle side.
b. Clean area after eliminating form insulator and foam material.
c. Install service part.
d. Insert nozzle into hole near fill area and fill foam ma terial or fill enough to close gap with the service part.
2. Fill procedures before installation of service part.
a. Eliminate foam material remaining on vehicle side.
b. Clean area after eliminating foam insulator and foam material.
c. Fill foam material on wheelhouse outer side.
