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.

CAUTION:
- If cylinder head bolts are reused, check their outer diameters before installation.
- Before installing cylinder head, inspect cylinder head distortion.

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

Torque : 105 N.m (11 kg-m, 77 ft-lb)

c. Completely loosen all cylinder head bolts.

Torque : 0 N.m (0 kg-m, 0 ft-lb)

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

d. Tighten all cylinder head bolts.

Torque : 40.0 N.m (4.1 kg-m, 30 ft-lb)

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.



Camshaft Bearing Cap Torque & Sequence
