Notice: This bolt is designed to permanently stretch when tightened, and therefore MUST be replaced anytime it is removed. The correct
part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.
Notice: This engine uses special torque to yield head bolts. This design bolt
requires a special tightening procedure. Failure to follow the given procedure
will cause head gasket failure and possible engine damage.
