MAINTENANCE AND REPAIR
ON–VEHICLE SERVICE
LUBRICATION
The hood hinges and the locking mechanisms require pe-
riodic lubrication for proper operation. Refer to Section 0B,
General Information for the specific types and intervals of
lubrication.
FASTENERS
Notice : Dissimilar metals in direct contact with each other
may corrode rapidly. Make sure to use the correct fasten-
ers to prevent premature corrosion.
Many aluminum components are used on current models.
Aluminum in contact with steel may corrode rapidly if it is
not protected by special finishes or isolators.
The fasteners used have a special finish which provides
adequate protection from corrosion. These special fasten-
ers differ in color in order to easily identify them from the
standard metric fasteners, which are medium blue.
When replacing fasteners, avoid substituting otherwise
similar fasteners in the same location.
ANTICORROSION MATERIALS
In order to provide rust resistance, anticorrosion materials
have been applied to the interior surfaces of most of the
metal panels. When you service these panels, properly re-
coat them with a service–type anticorrosion material if any
of the original material has been disturbed.
FRONT END SEALING
All locations where waterleaks may occur are sealed dur-
ing production with high quality, durable sealers. If it be-
comes necessary to reseal specific areas, use a high–
quality sealer of medium–bodied consistency which will
retain its flexible characteristics after curing and can be
painted, if necessary.
