103. NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means

to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. Use

a plastic scraping tool to remove all traces of the head gasket.

NOTE: Observe all warnings or cautions and follow all application directions contained on the packaging

of the silicone gasket remover and the metal surface prep.

NOTE: If there is no residual gasket material present, metal surface prep can be used to clean and

prepare the surfaces.

Clean the cylinder head-to-cylinder block mating surfaces of both the cylinder head and the cylinder block

in the following sequence.

1. Remove any large deposits of silicone or gasket material with a plastic scraper.

2. Apply silicone gasket remover, following package directions and allow to set for several minutes.

3. Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket

remover may be required if residual traces of silicone or gasket material remain.

4. Apply metal surface prep, following package directions, to remove any remaining traces of oil or

coolant and to prepare the surfaces to bond with the new gasket. Do not attempt to make the metal

shiny. Some staining of the metal surfaces is normal.

104. NOTE: LH shown, RH similar.

Support the cylinder heads on a bench with the head gasket side up. Check the cylinder head distortion

and the cylinder block distortion, paying particular attention to the oil pressure feed area. For additional

information, refer to
