Torque Data

Cylinder head bolts torque and sequence





Follow the steps to tighten the bolts in the numerical order shown in the figure to install cylinder head
Step a: 98.1 Nm (10 kg-m, 72 ft. lbs.)
Step b: 0 Nm Loosen in the reverse order of tightening.
Step c: 44.1 Nm (4.5 kg-m, 33 ft. lbs.)
Step d: 60° degrees clockwise
Step e: 60° degrees clockwise

Head Bolt reuse/replace
Cylinder Head Bolts Diameter





^ Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between d1 and d2 exceeds the limit, replace the bolts with new one.
Limit (d1 - d2): 0.18 mm (0.0071 inch)
^ If reduction of diameter appears in a position other than d2, use it as d2 point

Intake Manifold sequence





Tighten the intake manifold bolts in numerical order as shown.

Camshaft bearing sequence





Tighten fixing bolts of camshaft brackets as follows:
Camshaft bracket bolts
Step 1 (bolts 9-12): 1.96 Nm (0.2 kg-m, 17 inch lbs.)
Step 2 (bolts 1-8): 1.96 Nm (0.2 kg-m, 17 inch lbs.)
Step 3 (all bolts): 5.88 Nm (0.6 kg-m, 52 inch lbs.)
Step 4 (all bolts): 10.4 Nm (1.1 kg-m, 92 inch lbs.)

Main bearing cap bolts





Follow the steps to tighten each main bearing cap bolts.

Apply engine oil to threads and seating surface of bolts, and tighten all bolts temporarily.
Main bearing cap bolts in order of 1 to 10 : 39.2 Nm (4.0 kg-m, 29 ft. lbs.)
Main bearing cap sub bolt in order of 11 to 20 : 29.4 Nm (3.0 kg-m, 22 ft. lbs.)
Main bearing cap bolts in order of 1 to 10 : 40°
Main bearing cap sub bolt in order of 11 to 20 : 30°
Side bolt to in order of 21 to 30 : 49 Nm (5.0 kg-m, 36 ft. lbs.)

Exhaust Manifold nut sequence





Use a reliable straightedge and feeler gauge to check the flatness of each exhaust manifold flange surface.
Flatness limit 0.3 mm (0.012 inch)
