16. Position the RH heat shield and install the bolts.
^ Tighten to 10 Nm (89 inch lbs.).





17. NOTE: Install new O-ring seals and lubricate the O-ring seals with clean engine coolant.

Position the heater supply tube and the hoses as an assembly and install the stud bolt.
^ Tighten to 10 Nm (89 inch lbs.).





18. Position the ground strap and install the nut.
^ Tighten to 10 Nm (89 inch lbs.).

All cylinder heads

19. NOTE: Lubricate the camshaft and camshaft journals with clean engine oil prior to installation.

Install the LH and RH camshafts.





20. NOTE: LH shown, RH similar.

NOTE: Lubricate the camshaft bearing caps with clean engine oil.

Install the LH and RH camshaft bearing caps in their original locations.
^ Position the front camshaft bearing cap.
^ Position the remaining camshaft bearing caps.
^ Install the bolts loosely.
^ Tighten to 10 Nm (89 inch lbs.) in the sequence shown.





21. CAUTION: Damage to the camshaft phaser sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

NOTE: The RH and LH camshaft phaser sprockets are similar. Refer to the single timing mark to identify the RH camshaft phaser sprocket and the Liters timing mark to identify the LH camshaft phaser sprocket.

NOTE: LH shown, RH similar.

Install the camshaft phaser sprockets and new camshaft phaser bolts finger tight.





22. CAUTION: Damage to the camshaft phaser sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

CAUTION: Only use hand tools to remove the camshaft phaser sprocket assembly or damage may occur to the camshaft or camshaft phaser unit.

CAUTION: Damage to the camshaft phaser sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

NOTE: LH shown, RH similar.

Using the special tool, tighten the LH and RH camshaft phaser sprocket bolts in 2 stages.
^ Stage 1: Tighten to 40 Nm (30 ft. lbs.).
^ Stage 2: Tighten an additional 90 degrees.





23. Install the crankshaft sprocket, making sure the flange faces forward.





24. Rotate the crankshaft to position the crankshaft sprocket timing mark in the 6 o'clock position.





25. Rotate the camshaft sprockets to position the RH camshaft sprocket timing mark in the 11 o'clock position and the LH camshaft sprocket timing mark in the 12 o'clock position.

26. CAUTION: If one or both tensioner mounting bolts are loosened or removed, the tensioner-sealing bead must be inspected for seal integrity. Any cracks, tears, cuts or separation from the tensioner body, or permanent compression of the seal bead, will require replacement of the tensioner.

Inspect the RH and LH timing chain tensioners.
^ Install new tensioners, as necessary.





27. CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.

Compress the tensioner plunger, using a vise.





28. Install a retaining clip on the tensioner to hold the plunger in during installation.
29. Remove the tensioner from the vise.





30. If the copper links are not visible, mark one link on one end and one link on the other end and use as timing marks.





31. Install the 4 bolts and the LH and RH timing chain guides.
^ Tighten to 10 Nm (89 inch lbs.).





32. Position the lower end of the LH (inner) timing chain on the crankshaft sprocket, aligning the timing mark on the outer flange of the crankshaft sprocket with the single copper (marked) link on the chain.





33. NOTE: Make sure the upper half of the timing chain is below the tensioner arm dowel.

Position the LH timing chain on the camshaft sprocket. Make sure the camshaft sprocket timing mark is aligned with the copper (marked) chain link.





34. NOTE: The LH timing chain tensioner arm has a bump near the dowel hole for identification.

Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner and 2 bolts.
^ Tighten to 25 Nm (18 ft. lbs.).





35. Remove the retaining clip from the LH timing chain tensioner.





36. Position the lower end of the RH (outer) timing chain on the crankshaft sprocket, aligning the timing mark on the sprocket with the single copper (marked) chain link.





37. NOTE: The lower half of the timing chain must be positioned above the tensioner arm dowel.

Position the RH timing chain on the camshaft sprocket. Make sure the camshaft sprocket timing mark is aligned with the copper (marked) chain link.





38. Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner and 2 bolts.
^ Tighten to 25 Nm (18 ft. lbs.).





39. Remove the retaining clip from the RH timing chain tensioner.





40. NOTE: The RH and LH camshaft phaser sprockets are similar. Refer to the single timing mark to identify the RH camshaft phaser sprocket and the Liters timing mark to identify the LH camshaft phaser sprocket.

As a post-check, verify correct alignment of all timing marks. Make sure the timing marks on the sprockets correspond to the above note.
