- Remove and discard the 8 RH exhaust manifold studs.
- NOTICE: Do not use metal scrapers, wire brushes, power
abrasive discs or other abrasive means to clean the sealing surfaces. These
may cause scratches and gouges resulting in leak paths. Use a plastic
scraper to clean the sealing surfaces.
Clean the exhaust manifold mating surface of the cylinder head with metal surface prep. Follow the directions on the packaging.
- Remove the LH cylinder block drain plug.
- Allow coolant to drain from the cylinder block.

- NOTE: If the components are to be reinstalled, they must be
installed in the same positions. Mark the components for installation into
their original locations.
Remove the valve tappets from the cylinder head.
- Inspect the valve tappets. For additional information, refer to Section 303-00.
- Remove and discard the M6 bolt.
- NOTICE: Place clean, lint-free 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.
NOTICE: 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 torque-to-yield design and cannot be reused.
Remove and discard the 8 bolts from the cylinder head.- Remove the cylinder head.
- Discard the cylinder head gasket.
- 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 heads and the cylinder block in the following sequence.- Remove any large deposits of silicone or gasket material with a plastic scraper.
- Apply silicone gasket remover, following package directions, and allow to set for several minutes.
- 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.
- 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.
- 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 Section 303-00.

NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, may cause engine failure.
NOTICE: Whenever turbocharger air intake system components are removed, always cover open ports to protect from debris. It is important that no foreign material enter the system. The turbocharger compressor vanes are susceptible to damage from even small particles. All components should be inspected and cleaned, if necessary, prior to installation or reassembly.
