Tightening Torques

Cylinder Head
If either diameter is less than 10.6 mm (0.42 in.), replace the cylinder head bolt.





Tighten the cylinder head bolts in sequence to 39 N-m (4.0 kgf-m, 29 lbf-ft).
Use a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and do not overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt and retighten it from the first step.

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


Intake Manifold





Install the intake manifold (A) with a new gasket (B), and tighten the bolts and nuts in a crisscross pattern in two or three steps, beginning with the inner bolt.


Bearing Cap Bolts





Tighten the bearing cap bolts, in sequence 29 N-m (3.0 kgf-m, 22 lbf-ft)





Tighten the bearing cap bolts an additional 67°.





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


Connecting Rod
Tighten the connecting rod bolts 29 N-m (3.0 kgf-m, 22 lbf-ft)

Tighten the connecting rod bolts an additional 90°


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


Oil Pump






Exhaust Manifold





Install the exhaust manifold (D) with a new gasket (E) and new self-locking nuts (F) and bolts (G), and tighten the bolts and nuts in a crisscross pattern in two or three steps, beginning with the inner bolt.
