Cylinder Head Torque & Sequence








Install cylinder head, and tighten cylinder head bolts in numerical order as shown in figure as follows:
Use the cylinder head bolt wrench (commercial service tool: J- 24239-01) and power tool.

a. Apply new engine oil to threads and seat surfaces of cylinder head bolts.

b. Tighten all cylinder head bolts.






c. Completely loosen all cylinder head bolts.






CAUTION: In step "c", loosen bolts in the reverse order of that indicated in the figure.

d. Tighten all cylinder head bolts.






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

CAUTION:

Check the tightening angle using the angle wrench [SST: KV10112100 (BT8653-A)] (A). Never make judgment by visual inspection.
Check tightening angle indicated on the angle wrench indicator plate.

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



Re-usability

Cylinder Head Bolts Outer Diameter









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






If reduction of outer diameter appears in a position other than (A), use it as (A) point.
