System Specifications

Camshaft Bearing Caps








Examine the front marks and numbers and check that the sequence order is as shown in the illustration. Then tighten the bolts.
Torque:
Bearing cap No. 1 23 Nm (235 kgf-cm, 17 ft. lbs.)
Bearing cap No. 3 13 Nm (133 kgf-cm, 10 ft. lbs.)

HINT:
- Bearing Cap No.1 = No. 9 in illustration
- Bearing Cap No.3 = Nos. 1-8 in illustration

Inspect Cylinder Head





Inspect for flatness. Using a precision straight edge and a feeler gauge, measure the surface contacting the cylinder block and the manifolds for warpage.
Maximum warpage 0.05 mm (0.0020 inch)
If warpage is greater than maximum, replace the cylinder head.





Cylinder Head Bolt
Standard overall length 156.0 - 159.0 mm (6.142 - 6.260 inch)
Maximum overall length 159.5 mm (6.280 inch)





Cylinder Head Bolt Torque and Sequence
Using a 10 mm bi-hexagon wrench, install and uniformly tighten the 10 cylinder head bolts and plate washers in several passes, in the sequence shown.
Torque 49 Nm (500 kgf-cm, 36 ft. lbs.)





Mark the front of the cylinder head bolt with paint.
Retighten the cylinder head bolts 90° in the numerical order shown.
Check that the painted mark is now at a 90° angle to the front.
Install the bolt holding the water bypass pipe to the cylinder head.
Torque 9 Nm (92 kgf-cm, 80 inch lbs.)

Camshaft Gear
Torque 54 Nm (551 kgf-cm, 40 ft. lbs.)

Intake Manifold And Throttle Body Assembly

Torque 30 Nm (306 kgf-cm, 22 ft. lbs.)





Intake Manifold
Using a precision straight edge and a feeler gauge, measure he surface contacting the cylinder head for warpage.
Maximum warpage 0.10 mm (0.0039 inch)


Exhaust Manifold Torque
Install a new gasket and the exhaust manifold with the 5 nuts.
Torque 37 Nm (377 kgf-cm, 27 ft. lbs.)
Install the 2 exhaust manifold stays with the 4 bolts.
Torque 37 Nm (377 kgf-cm, 27 ft. lbs.)
Place the upper heat insulator on the exhaust manifold.
Install the 2 heated oxygen sensors.
Torque 44 Nm (450 kgf-cm, 32 ft. lbs.)





Exhaust Manifold
Using a precision straight edge and a feeler gauge, measure the surface contacting the cylinder head for warpage.
