NOTE: The engine comes equipped with either a roller primary timing chain or an inverted tooth primary timing chain. The roller timing chain engine comes equipped with either a composite RH timing chain guide requiring the timing chain to ride on the outer side of the guide or a stamped steel RH timing chain guide requiring the timing chain to ride on the inner side of the guide. All roller timing chain engine replacement RH timing chain guides will be the stamped steel design.

NOTE: Place clean shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages or the oil pan, may cause engine failure.
NOTE: Aluminum surfaces are soft and may be scratched easily. Never place the cylinder head gasket surface, unprotected, on a bench surface.
NOTE: The cylinder head bolts must be discarded and new bolts must be installed. They are a tighten-to-yield design and cannot be reused.

31. Remove and discard the 8 bolts from the cylinder head.
    • Remove the cylinder head.
    • Discard the cylinder head gasket.
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: 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.
32. Clean the cylinder head-to-cylinder block mating surfaces of both the cylinder heads 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.
33. Support the cylinder head on a bench with the head gasket side up. Check the cylinder head distortion and the cylinder block distortion. For additional information, refer to ENGINE SYSTEM - GENERAL INFORMATION article.
