Cylinder Head Torque & Sequence






Follow the steps below to tighten cylinder head bolts in numerical order as shown.

Step a 98.1 Nm (10 kg-m, 72 ft-lb)
Step b Loosen to 0 Nm in the reverse order of tight ening.
Step c 39.2 Nm (4.0 kg-m, 29 ft-lb)






Measure the tightening angle using Tool

Tool number: KV-10112100 (BT-8653-A)

Step d 90� clockwise
Step e 90� clockwise

Re-Usability

CAUTION: If cylinder head bolts are re-used, 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 the bolt with a new one.

Limit [(d1) - (d2)]: 0.11 mm (0.0043 in)

If reduction of outer diameter appears in a position other than (d2), use it as (d2) point
