Unscrew the bolts securing the valve lever shaft. Remove the shaft together with the valve levers (do not disassemble this subassembly).
Remove the pushrods and save them with the appropriate mounting marks. The pushrods must be mounted together with the pushrods and levers with which they previously interacted.
Loosen the mounting bolts and remove the cylinder head. If the cylinder head is strongly "stuck" to the gasket, detach it using light blows from a plastic hammer. Under no circumstances should any tools be inserted between the cylinder head and the engine body. If there is water or oil in the cylinders, remove it.
The cylinder head is installed in the reverse order. When performing this operation, the section on engine assembly 1.1 may be helpful.
Fill and bleed the engine cooling system (see section 2.8 "Cooling system").
