Tightening Fasteners

Use the correct amount of torque when you tighten fasteners on the engine. Applying

excessive torque may damage the fastener or component and not enough torque may

cause a leak or component failure.

NOTICE

he tightening torque in the Standard Torque Chart should be applied only to the

bolts with a “7” head (JIS strength classification: 7T). Apply 60% torque to bolts

that are not listed. Apply 80% torque when tightened to aluminum alloy.

When lock adhesive is applied, decide separately.
