Disassembly

Note. During engine repair procedures, cleanliness is extremely important. Any foreign material, including material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.

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

Note. If the components are to be reinstalled, they must be installed in the same positions. Mark the components removed for locations.
