For 1990-2009 cars only

This vehicle has a utilized body with a frame assembly supporting the engine and the transaxle. The fender panels and the radiator support are also integral parts of the body.

Lubrication

The hood hinges and the locking mechanisms require periodic lubrication for proper operation. Refer to Fluid and Lubricant Recommendations in Maintenance and Lubrication.

Fasteners

Notice: Refer to Fastener Notice in the Preface section.

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 fasteners 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.

Anti-corrosion Materials

In order to provide rust resistance, anti-corrosion materials have been applied to the interior surfaces of most of the metal panels. When you service these panels, properly 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 during production with high quality, durable sealers. If it becomes 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.
