New Car injection molding parts that need to be understood

The most important point to ensure the normal service life of New Car injection molding parts is that the engine cylinder gasket cannot be installed upside down during installation, otherwise it will cause premature burning and damage to the cylinder gasket. The engine fan blades must not be installed upside down; for tires with directional patterns and herringbone pattern tires, the ground imprint after installation should make the herringbone tip point to the rear.
