Valves and Cylinder Heads Removal and Installation

Removal
1. Remove engine assembly from vehicle.
2. Remove camshafts tappets and shims.
3. Remove exhaust manifold.
4. Remove water outlet cap.
5. Loosen cylinder head bolts in such order ("1" - "8ff) as shown in figure and remove them.

NOTE:
Be sure to remove 2 hex bolts (1) shown in figure.








6. Remove cylinder heads.

Installation
1. Clean mating surface on cylinder head and cylinder block. Remove oil, old gasket and dust from mating surface.
2. Install knock pin (4) to cylinder block.
3. Install new cylinder head gasket (1) to cylinder block as shown in figure. Carved lot number (5) on cylinder head gasket (1) should face up (toward cylinder head side).








4. Install cylinder head to block.

After applying oil to cylinder head bolts, tighten them gradually as follows.
a) Tighten cylinder head bolts (except hex hole bolt) to 53 Nm (5.3 kgf-m, 38.5 ft. lbs.) according to numerical order in figure.
b) In the same manner as Step a), tighten them to 84 Nm (8.4 kgf-m, 61.0 ft. lbs.).
c) Loosen all bolts until tightening torque is reduced to 0 in reverse order of tightening.
d) In the same manner as Step a), tighten them to 53 Nm (5.3 kgf-m, 38.5 ft. lbs.).
e) In the same manner as Step a) again, tighten them to 105 Nm (10.5 kgf-m, 76.0 ft. lbs.).
f) Tighten cylinder head bolts (hex hole bolt) to specified torque.

Tightening torque
Cylinder head bolt (a): Tighten 53 Nm (5.3 kgf-m, 38.5 ft. lbs.), 84 Nm (8.4 kgf-m, 61.0 ft. lbs.), 0 Nm (0 kgf-m, 0 ft. lbs.), 53 Nm (5.3 kgf-m, 38.5 ft. lbs.) and 105 Nm (10.5 kgf-m, 76.0 ft. lbs.) by the specified procedure
Cylinder head bolt (hex hole bolt) (b): Tighten 11 Nm (1.1 kgf-m, 7.5 ft. lbs.) by the specified procedure

NOTE:
Be sure to install hex hole bolts (1) as shown in figure.








5. Install water outlet cap.
6. Check timing mark on crankshaft as shown in figure.








7. Install tappets, shims, camshafts, and RH (No. 2) bank 2nd timing chain.

8. Install 1st timing chain.
9. Install LH (No. 1) bank 2nd timing chain.
10. Install timing chain cover.
11. Install oil pans and oil pump strainer.
12. Install cylinder head covers.
13. Install exhaust manifold.
14. Install radiator outlet pipe.
15. Install intake manifold, intake collector and electric throttle body assembly.
16. Install engine assembly to vehicle.
