Cylinder Head: Installation

WARNING: This page is about a different variant/trim than selected.

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

NOTE: Clean the cylinder head bolt holes in the cylinder block. Make sure all coolant, oil or other foreign material is removed.

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.
