10. Remove the cylinder head cover (see subsection 3.2.1.4).
11. Turn away bolts and remove directing from a head of cylinders.
Chain sprockets
12. Remove the chain and camshaft sprockets (see subsection 3.2.1.7). If the chain will not be removed, then unscrew the sprocket bolts from both camshafts (see clause 9 of subsection 3.2.1.7), put identification marks on the gears so that they can be installed in their original place during assembly.
Status check
See subsection 3.2.1.7.
Installation
Chain tensioner
1. Make sure the contact surfaces of the tensioner and cylinder head cover are clean.
2. Release tensioner release lever (1), push the plunger inside the body and fix it in this position with a hook, throwing it over the plunger pin (2).
3. Install a new gasket on the tensioner flange, and put a new o-ring in the housing groove.
4. Install the tensioner, making sure the arrow on the flange points away from the cylinder head. Put on the washers and tighten the tensioner nuts to the specified torque. After tightening the nuts, the mounting hook should automatically disengage from the pin, releasing the plunger.
