The cylinder head bolts have to withstand tremendous loads to keep the cylinder head sealed tightly against the head gasket and the cylinder block. Head bolts are truly one of the most critical fasteners in any engine. Consequently, it’s extremely important that all the head bolts be in perfect condition and are installed and lubricated properly so they are not overloaded. Use an accurate torque wrench to tighten standard type head bolts in 3 to 5 incremental steps following the manufacturers recommended sequence and torque specifications for the application.
