5.Remove the coolant outlet housing. Refer to "Removal and Installation" Removal And Installation.





6.Remove the RH and LH cylinder head bolts, with power tool.
- The bolts should be loosened gradually in three stages.
- Loosen the bolts in the numerical order as shown.

- Discard the cylinder head gaskets and use new gaskets for installation.

INSTALLATION






1.Turn the crankshaft until No. 1 piston is set at TDC on the compression stroke.
- The crankshaft key should line up with the right bank cylinder center line as shown.





2.Install new gaskets on the cylinder heads.
3.Inspect the cylinder head bolts before installing the cylinder heads.

CAUTION:





Cylinder head bolts are tightened by degree rotation tightening method. Whenever the size difference between d1 and d2 exceeds the limit, replace the bolts with new ones.

Limit (d1 - d2): 0.11 mm (0.0043 in)

-Lubricate threads and seat surfaces of the bolts with new engine oil.





4.Install the cylinder heads on the cylinder block. Tighten the cylinder head bolts in five steps in the numerical order as shown using Tool.
Tool Number: KV10112100 (BT-8653-A)
-Tightening procedure:





Cylinder head bolts
Step a: 98.1 Nm (10 kg-m, 72 ft-lb)
Step b: Loosen in the reverse order of tightening
Step c: 39.2 Nm (4.0 kg-m, 29 ft-lb)
Step d: 103� degrees rotation clockwise
Step e: 103� degrees rotation clockwise





5.Installation of the remaining components is in the reverse order of removal.
