Torque specifications are for
stock factory type bolts with light engine oil applied to the threads
and the underside of the bolt head. Other lubrications offer reduced
friction and increased bolt tension, and will affect the torque figure.
If using aftermarket performance bolts, you should follow the
recommended torque specifications of the aftermarket bolts.
*Please Note: Some specifications listed below are in
inch-pounds rather than foot-pounds. Over torqueing will result in
broken bolts.
*
Torque values shown are in ft/lbs unless otherwise
noted - Follow factory torque sequence.
