3. Apply sealant "A" to cylinder head gasket as shown in figure.
"A": Sealant 99000-31150
Width "w": Min. 4 mm (0.158 inch)
4. Install new cylinder head gasket to cylinder block as shown in figure. "86FA" mark on cylinder head gasket should face up (toward cylinder head side).





5. Install cylinder head to block. After applying oil to cylinder head bolts, tighten them gradually as follows.
1. Tighten all bolts to 53 Nm (5.3 kg-m, 38.5 ft. lbs.) according to numerical order in figure.
2. In the same manner as in (1), tighten them to 84 Nm (8.4 kg-m, 61.0 ft. lbs.).
3. Loosen all bolts until tightening torque is reduced to 0 in reverse order of tightening.
4. In the same manner as in (1), tighten them to 53 Nm (5.3 kg-m, 38.5 ft. lbs.).
5. In the same manner as in (1) again, tighten them to specified torque.
Tightening Torque
(a): 105 Nm (10.5 kg-m, 76.0 ft. lbs.)
(b): 11 Nm (1.1 kg-m, 7.5 ft. lbs.)

NOTE: Don't forget to install (b) bolts as shown in figure.

6. Install water outlet cap.





7. Check timing mark on crankshaft as shown in figure.
8. Install valve lash adjuster, camshaft, CMP sensor and RH bank 2nd timing chain.
