Installation (Steps 1-35)
All cylinder heads
1. CAUTION: Make sure all coolant residue and foreign material are cleaned from the block surface and cylinder bore.
CAUTION: The use of sealing aids (aviation cement, copper spray, and glue) is not permitted. The gasket must be installed dry.
CAUTION: The cylinder head bolts must be discarded and new bolts installed. They are tighten-to-yield designed and cannot be reused.
NOTE: Do not turn the crankshaft until instructed to do so.
NOTE: LH shown, RH similar.
Using the special tools, position the cylinder head gaskets and cylinder heads over the dowels and install the cylinder head bolts loosely.
2. NOTE: RH shown, LH similar.
Tighten the bolts in 3 stages, in the sequence shown.
^ Stage 1: Tighten to 40 Nm (30 ft. lbs.)
^ Stage 2: Tighten an additional 90 degrees.
^ Stage 3: Tighten an additional 90 degrees.
LH cylinder head
3. Remove the special tool from the LH cylinder head.
4. Install the hydraulic lash adjusters into the LH cylinder head.
^ Lubricate the hydraulic lash adjusters with clean engine oil prior to installation.
5. Install 8 new exhaust manifold studs.
^ Tighten to 12 Nm (9 ft. lbs.)
6. Position a new gasket, the LH exhaust manifold and tighten the 8 new nuts in the sequence shown.
^ Tighten to 25 Nm (18 ft. lbs.)
7. Position the exhaust manifold heat shield and install the 3 bolts.
RH cylinder head
8. Remove the special tool from the RH cylinder head.
9. Install the hydraulic lash adjusters into the RH cylinder head.
^ Lubricate the hydraulic lash adjusters with clean engine oil prior to installation.
10. Install 8 new exhaust manifold studs.
^ Tighten to 12 Nm (9 ft. lbs.)
11. Position a new gasket, the RH exhaust manifold and tighten the 8 new nuts in the sequence shown.
^ Tighten to 25 Nm (18 ft. lbs.)
12. Install the coolant tube and the stud bolt.
^ Tighten to 10 Nm (89 inch lbs.)
All cylinder heads
13. Install the LH and RH camshafts.
^ Lubricate the camshaft and camshaft journals with clean engine oil prior to installation.
14. NOTE: LH shown, RH similar.
Install the LH and RH camshaft bearing caps in their original locations.
^ Lubricate the camshaft bearing caps with clean engine oil.
^ 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.
15. CAUTION: Damage to the variable camshaft timing (VCT) phaser sprocket assembly will occur if mishandled or used as a lifting or leveraging device.
NOTE: LH shown, RH similar.
Install the VCT phaser sprockets and new VCT phaser sprocket bolts finger tight.
16. CAUTION: Damage to the VCT phaser sprocket assembly will occur if mishandled or used as a lifting or leveraging device.
CAUTION: Only use hand tools to remove the VCT phaser sprocket assembly or damage may occur to the camshaft or VCT phaser sprocket.
NOTE: LH shown, RH similar.
Using the special tool, tighten the LH and RH VCT phaser sprocket bolts in 2 stages.
^ Stage 1: Tighten to 40 Nm (30 ft. lbs.)
^ Stage 2: Tighten an additional 90 degrees.
17. CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.
CAUTION: Prior to installation, inspect the tensioner-sealing bead for seal integrity. If cracks, tears, separation from the tensioner body or permanent compression of the seal bead is observed, install a new tensioner.
Compress the tensioner plunger, using a vise.
18. Install a retaining clip on the tensioner to hold the plunger in during installation.
19. Remove the tensioner from the vise.
20. If the copper links are not visible, mark 2 links on one end and 1 link on the other end, and use as timing marks.
21. Position the crankshaft keyway at the 11 o'clock position.
22. Install the crankshaft sprocket, making sure the flange faces forward.
23. Install the 4 bolts and the LH and RH timing chain guides.
^ Tighten to 10 Nm (89 inch lbs.)
24. 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.
25. NOTE: Make sure the upper half of the timing chain is below the tensioner arm dowel.
Position the timing chain on the VCT phaser sprocket with the timing mark positioned between the 2 copper (marked) chain links.
26. 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 bolts.
^ Tighten to 25 Nm (18 ft. lbs.)
27. Remove the retaining clip from the LH timing chain tensioner.
28. 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.
29. NOTE: The camshaft phaser and sprocket will be stamped with one of the illustrated timing marks for the RH camshaft.
Position the RH timing chain on the VCT phaser sprocket with the timing mark positioned between the 2 copper (marked) chain links.
30. Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner and bolts.
^ Tighten to 25 Nm (18 ft. lbs.)
31. Remove the retaining clip from the RH timing chain tensioner.
32. As a post-check, verify correct alignment of all timing marks.
33. Install the crankshaft sensor ring on the crankshaft.
34. Using the special tool, install all of the camshaft roller followers.
^ Lubricate the camshaft roller followers with clean engine oil prior to installation.
35. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.
NOTE: If the engine front cover is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with silicone gasket remover and metal surface prep. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.
NOTE: Make sure that the engine front cover gasket is in place on the engine front cover before installation.
Apply a bead of silicone gasket and sealant along the cylinder head-to-cylinder block surface and the oil pan-to-cylinder block surface, at the locations shown.
