INSPECTION AFTER REMOVAL

Outer Diameter of Cylinder Head Bolts
- Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between d1 and d2 exceeds the limit, replace the bolts with new ones.





Limit (d1 - d2) : 0.23 mm (0.0091 in) or less

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

INSTALLATION
1. Install a new cylinder head gasket.
2. Install the cylinder head.
3. Follow the steps below to tighten the cylinder head bolts in the numerical order as shown.
- Apply new engine oil to the threads and the seating surfaces of bolts.

CAUTION:
- If cylinder head bolts are re-used, check their outer diameters before installation. Follow the
Outer Diameter of Cylinder Head Bolts measurement procedure.
- Check and confirm the tightening angle by using angle wrench or protractor. Avoid judgment by visual inspection without the tool.
