Cylinder Head Bolt Reusability

- Inspect the cylinder head bolts before installing the cylinder head.

CAUTION: Cylinder head bolts are tightened by degree rotation tightening method. Whenever the size difference between d1 and d2 exceeds the limit, replace the bolts with new ones.

- Subtract the head bolt diameter measurement taken at d2 from the head bolt diameter measurement taken at d1. If the difference between d1 and d2 exceeds the limit, replace the bolts with new ones.
