Cylinder Head

Tighten the cylinder head bolts in the order shown with the following 5 steps using the SST (49 D032 316).






Tightening torque
Step 1 3-11 Nm {30.6-112 kgf-cm, 26.6-97.3 in-lbf}
Step 1 13-17 Nm {1.4-1.7 kgf-m, 9.59-12.5 ft-lbf}
Step 1 43-47 Nm {4.4-4.7 kgf-m, 31.8-34.6 ft-lbf}
Step 1 88°-92°
Step 1 88°-92°

Cylinder Head Surface Variation





^ Measure the cylinder head for distortion in six directions as shown in the figure.
^ If it exceeds the maximum specification, replace the cylinder head.
^ Cylinder head gasket contact surface distortion (Maximum) 0.10 mm (0.004 in)
^ Measure the manifold contact surface distortion as shown in the figure.
^ If it exceeds the maximum specification, grind the surface or replace the cylinder head.
Manifold contact surfaces distortion (Maximum) 0.10 mm (0.004 in)
Manifold contact surfaces distortion (Maximum grinding) 0.15 mm (0.006 in)
