Tightening Torques and Sequences

Cylinder Head Torque and Sequence
Tighten the cylinder head bolts in sequence to 39 N-m (4.0 kgf-m, 29 lbf-ft).



After torquing, tighten all cylinder head bolts in two steps (90 ° per step) using the sequence shown. If you are using a new cylinder head bolt, tighten the bolt an extra 90 °.


Head Bolt Reuse/Replace
Measure the diameter of each cylinder head bolt at point A and point B.
If either diameter is less than 10.6 mm (0.42 in.), replace the cylinder head bolt.





Intake Manifold Torque





Camshaft Bearing Cap Torque and Sequence






Tighten the bolts to the specified torque.
NOTE: If the engine does not have bolt 21, skip it and continue the torque sequence.


Main Bearing Cap Torque and Sequence
Tighten the bearing cap bolts in sequence, to 29 N-m (3.0 kgf-m, 22 lbf-ft).



Tighten the bearing cap bolts an additional 48 °.



Tighten the 8 mm bolts in sequence to 22 N-m (2.2 kgf-m, 16 lbf-ft).





Rod Bearing Cap Torque
Tighten the connecting rod bolts to 41 N-m (4.2 kgf-m, 30 lbf-ft).
Tighten the connecting rod bolts an additional 120 °.





Connecting Rod Bolt Reuse/Replace
Measure the diameter of each connecting rod bolt at point A and point B.
Calculate the difference in diameter between point A and point B.
Point A-Point B = Difference in Diameter
If the difference in diameter is out of specification, replace the connecting rod bolt.








Crankshaft Pulley Torque
Tighten the bolt to 49 N-m (5.0 kgf-m, 36 lbf-ft)
If the pulley bolt or crankshaft are new, tighten the bolt to 177 N-m (18.0 kgf-m, 130 lbf-ft), then remove the bolt and tighten it to 49 N-m (5.0 kgf-m, 36 lbf-ft).
Tighten the pulley bolt an additional 90 °.


Flexplate Torque and Sequence
Torque the flexplate mounting bolts in a crisscross pattern in several steps.





Flywheel Torque and Sequence
Torque the flywheel mounting bolts in a crisscross pattern in several steps.
