Thoroughly clean all parts to be assembled.
Always use new cylinder head bolts. Cylinder head bolts are torque-to-yield bolts designed to be permanently elongated beyond the state of elasticity when torqued, so if the bolts are removed and reused, it may cause the bolts to break or fail to maintain clamping force.
The cylinder head gasket is a metal gasket. Take care not to bend it.
Rotate the crankshaft, set the No.1 piston at TDC.
Install the cylinder head gasket.
The sealant locations on cylinder head gasket, cylinder block and timing chain lower case must be free of engine oil and etc.
Apply sealant TB1217 or LT5900 on the cylinder block top surface (Refer to below illustration) before assembling the cylinder head gasket.
Bead width : 2.0 ~ 3.0 mm (0.0787 ~ 0.1181 in)
Install the cylinder head gasket on the cylinder block.
Be careful of the installation direction.
Apply sealant TB1217 or LT5900 on the cylinder head gasket top surface (Refer to below illustration) after assembling the cylinder head gasket.
Bead width : 2.0 ~ 3.0 mm (0.0787 ~ 0.1181 in)
Remove the extruded sealant after assembling the cylinder head assembly.
Install the cylinder head assembly.
Place the cylinder head assembly (A) quietly in order not to damage the gasket (B) with the bottom part of the end.
Using SST (09221-4A000), tighten the cylinder head bolts and plate washers, in several passes, in the sequence shown.
Tightening torque :
12.7 ~ 16.7 N.m (1.3 ~ 1.7 kgf.m, 9.4 ~ 12.3 lb-ft) + 90 ~ 95° + 120 ~ 125°
Always use new cylinder head bolts. Cylinder head bolts are torque-to-yield bolts designed to be permanently elongated beyond the state of elasticity when torqued, so if the bolts are removed and reused, it may cause the bolts to break or fail to maintain clamping force.
Install the other parts in the reverse order of removal.
