18. Install the third camshaft drive gear retaining bolt and tighten the bolt to 18 Nm (13 ft. lbs.).

WARNING: If the camshaft, balance shaft and or crankshaft alignment marks are not aligned properly immediate damage to the engine will occur. If the camshafts, balance shaft and or crankshaft do not align properly after rotating the engine to the original starting point, STOP and begin the alignment procedure again.

19. Rotate the engine back to TDC by the vibration damper bolt until the crankshaft, camshaft and balance shaft align TDC again.




WARNING: Check that all the timing chain fits properly on all the timing gears. Failure to do so will result in immediate engine damage.

20. Apply a 1.5mm continuous bead of Mopar Engine Sealant RTV around the diameter of the timing chain cover (1) and Install the cover (1). Tighten the bolts to 8.4 Nm (74 in. lbs.).

23. Install special tool #9102 crankshaft lock (2) into the starter access blank.
24. Lower the vehicle.




25. Install the vibration damper. Tighten the bolts to 200 Nm (148 ft. lbs.) and then an additional 90°.




NOTE: Care must be taken not to get any engine sealer on the camshaft journals.

26. Apply a 1.5mm continuous bead of Mopar Engine Sealant RTV (1) around the diameter of the left cylinder head cover, and install the cover with new camshaft seals.




27. Tighten the bolts in three stages following the sequence provided. First to 4 Nm (35 in. lbs.), then to 6 NmM (53 in. lbs.), and then to 8.4 NmM (75 in. lbs.).




28. Install the oil filter housing bracket. Tighten the bolts to 13.8 Nm (122 in. lbs.).
29. Install the high pressure pump. Tighten bolts to 13.5 Nm (120 in. lbs.).

31. Install the drive belt tensioner (2). Tighten the bolts to 58 Nm (43 ft. lbs.).
32. Install the drive belt.




CAUTION: The right intake manifold upper thermostat housing bolts should be tightened to 8.4 Nm (74 in. lbs.).

33. Install the intake manifold (4). Tighten bolts to 16 Nm (142 in. lbs.), starting in the middle and tightening in a cross pattern outward until reaching the upper thermostat bolts on the right front manifold.
34. Tighten the upper thermostat bolts on the right cylinder head to 8.4 Nm (74 in.lbs.).




CAUTION: The fuel injector sealing washers MUST be replaced. DO NOT use the old sealing washers or double the sealing washers.

35. Lubricate the fuel injector body (1), install the left fuel injectors (1) and new lower sealing washers.
