Cylinder Head Assembly

Cylinder Head Torque & Sequence





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

CAUTION: If cylinder head bolts are re-used, check their diameters before installation. Follow the "Cylinder Head Bolts Diameter" procedure.

Apply engine oil to threads and seating surface of the bolts.





Measure the tightening angle using Tool.

CAUTION: Measure the tightening angle using Tool. Do not measure visually.






Re-usability

Cylinder Head Bolts 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.





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