Installation

INSTALLATION

NOTE:
^ Thoroughly clean all parts to be assembled.
^ Always use a new head and manifold gasket.
^ The cylinder head gasket is a metal gasket. Take care not to bend it.
^ Rotate the crankshaft, set the No. 1 piston at TDC.

1. Install the cylinder head.
a. The sealant locations on cylinder head and cylinder block must be free of engine oil and ETC.
b. Apply sealant on cylinder block top face before assembling cylinder head gaskets.
The part must be assembled within 5 minutes after sealant was applied.





NOTE:
Refer to the illustration below to apply the sealant.





c. Apply sealant on cylinder head gaskets after assembling cylinder head gaskets on cylinder block. The part must be assembled within 5 minutes after sealant was applied.





NOTE:
Be careful of the installation direction.





d. Install the cylinder head.

NOTE:
Remove the extruded sealant after assembling cylinder heads.





2. Place the cylinder head carefully to avoid damaging the gasket.
3. Install cylinder head bolts.

1) Do not apply engine oil on the threads and under the heads of the cylinder head bolts.
2) Using SST (09221-4A000), install and tighten the cylinder head bolts and plate washers, in several passes, in the sequence shown.

Tightening torque
1st step : 37.3 - 41.2 Nm (3.8 - 4.2 kgf.m, 27.5 - 30.4 lb - ft)
2nd step : 120° ±2°
3rd step : 90° ±2°
18.62 - 23.52 Nm (1.9 - 2.4 kgf.m, 13.74 - 17.36 lb - ft) (A)

NOTE:
Always use new cylinder head bolts.











4. Install the CVVT and camshaft sprocket.





NOTE:
^ Install camshaft-inlet to dowel pin of CVVT assembly.
At this time, do not install to oil hole of camshaft inlet.
^ Hold the hexagonal head wrench portion of the camshaft with a vise, and install the bolt and CVVT assembly.
^ Do not rotate CVVT assembly when camshaft is installed to dowel pin of CVVT assembly.

5. Install camshafts (A).

NOTE:
^ Apply a light coat of engine oil on camshaft journals.
^ Assemble the key groove of camshaft rear side to the same level of head top surface.
^ Be careful the right, left bank, intake, exhaust side before assembling.











6. Install camshaft bearing caps as following order.





NOTE:
Be careful the right, left bank, intake, exhaust side, front mark before assembling.





CAUTION:
Rotate the crankshaft so as not to contact the valves to the pistons by positioning, the pistons below 10 mm (0.3937 in.) from the top of cylinder block.

7. Install water temperature control assembly.
8. Install timing chain.
9. Check and adjust valve clearance.
10. Install the exhaust manifold.
11. Install the intake manifold.
