Cylinder Head Cleaning

Cylinder Head Cleaning





1. NOTICE: Do not clean the cylinder heads with steel scrapers or blades, which can cause scratches or gouges that result in leak paths. Also, do not use rotary abrasive tools including: pads, disc, wire brushes, sand paper or emery cloth. These products can alter the surface finish of the head, adversely affecting the combustion chamber sealing.

NOTICE: Aluminum surfaces are soft and can be scratched easily. Never place the cylinder head gasket surface, unprotected, on a bench surface.

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

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

2. Apply silicone gasket remover, following the 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 gasket material remain.

4. NOTE: Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.

Apply metal surface prep, following the package directions, to remove any remaining traces of oil or coolant, and to prepare the surfaces to bond with the new gasket.
