Tighten cylinder head bolts in numerical order as shown in the figure with the following procedure.

Tighten all cylinder head bolts:






Turn all cylinder head bolts 100 degrees clockwise (angle tightening).

CAUTION:






Check and confirm the tightening angle by using an angle wrench [SST: KV-10112100 (BT-8653-A)] (A) or protractor.

Completely loosen






CAUTION:
In this step, loosen cylinder head bolts in reverse order that indicated in the figure.

Tighten all cylinder head bolts:






Turn all cylinder head bolts 95 degrees clockwise (angle tightening).
Turn all cylinder head bolts 95 degrees clockwise again (angle tightening).

Re-usability

CAUTION: If cylinder head bolts are reused, check their outer diameters before installation.



Cylinder Head Bolts Outer Diameter






Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between (d1) and (d2) exceeds the limit, replace them with a new one.

Limit [(d1) - (d2)]: 0.15 mm (0.0059 in)
