Tightening Torque

Cylinder Head J35A6





6 point Cylinder Head Bolts Tighten the cylinder head bolts sequentially in three steps.

NOTE: Perform each step twice.

1st Step Torque 39 Nm (4.0 kgf-m, 29 ft. lbs.)
2nd Step Torque 69 Nm (7.0 kgf-m, 51 ft. lbs.)
3rd Step Torque 98.1 Nm (10.0 kgf-m, 72.3 ft. lbs.)
Use a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and not to overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt, and retighten it from the 1st step.

12 point Cylinder Head Bolts

NOTE: Do not intermix head bolt types on the same cylinder head.





Tighten the cylinder head bolts in sequence to 30 Nm (3.0 kgf-m, 22 ft. lbs.) 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°.

Cylinder Head J35A7

Perform each step twice.





1st Step Torque 39 Nm (4.0 kgf-m, 29 ft. lbs.)
2nd Step Torque 69 Nm (7.0 kgf-m, 51 ft. lbs.)
3rd Step Torque 98.1 Nm (10.0 kgf-m, 72.3 ft. lbs.)
Use a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and not to overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt, and retighten it from the 1st step.


Intake Manifold





Tighten the bolts and nuts sequentially in two or three steps. Always use a new intake manifold gasket.


Crankshaft Pulley





1 Hold the pulley with the holder handle (A) and holder attachment (B), then tighten the bolt to 64 Nm (6.5 kgf-m, 47 ft. lbs.) with a torque wrench and heavy duty 19 mm socket (C).
2 Mark the bolt head (D) and crankshaft pulley (E) as shown, then tighten the bolt an additional 60° (The mark on the bolt head line up with the mark on the crankshaft pulley).


Crankshaft Bearing Cap





Tighten the bearing cap bolts, and then the bearing cap side bolts to the specified torque in the sequence as shown. Repeat the torque sequence again to measure the bolts are properly torqued.
