TORQUE
After tightening cap screws to 150 Nm (110 lb-ft), use
JT05993 Torque Angle Gauge or the line scribe method
below to tighten each cap screw an additional 60.
Line scribe method:
Step A--Make two marks on socket 1/6 turn (6010)
apart.
Step B--Make a mark on cylinder head next to each cap
screw.
Step C--Place socket on cap screw so first mark aligns
with mark on cylinder head.
Step D--Tighten (in sequence) all cap screws until
second mark on socket aligns with mark on cylinder head.
Retorque of cylinder head cap screws after engine
break-in is not required when using the recommended
torque procedure along with flanged-head cap screws.
