CORROSION PREVENTION AND SEALING

INTERNAL SEALING 77-4-29

Replacing seals
As paint oven temperatures used in a repair workshop are significantly lower than those that are used during 
manufacture of the vehicle, a different process is required to replace the seals in service. When replacing a seal, the 
following procedure must be followed.
 After a repair that involves replacement of a section containing expanded foam, the new section must be injected 
with an approved sound dampening foam. The sound dampening foam should be injected after paint refinishing and 
application of cavity wax.

Accessible cavities that must be injected with sound dampening foam are detailed in the following Figures. When 
injecting the foam, ensure the foam fills a complete cross section of the cavity.

Cavities symmetrically opposite to those shown must also be treated.
