Removal

1. Remove the engine front cover. For additional information, refer to Engine Front Cover Service and Repair.

2. Position the crankshaft keyway at the 11 o'clock position.





3. Remove the 2 bolts, the RH timing chain tensioner and tensioner arm.





4. Remove the bolt and the RH timing chain guide.





5. Remove the RH timing chain.





6. Remove the 2 bolts and the LH timing chain tensioner.





7. Remove the LH timing chain tensioner arm.





8. Remove the bolt and the LH timing chain guide.





9. Remove the LH timing chain.





10. Remove the crankshaft sprocket.





Installation

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

1. Compress the tensioner plunger, using a vise.





2. Install a retaining clip into the tensioner to hold the plunger in during installation.





3. Remove the tensioner from the vise.

4. If the blue links are not visible, mark 2 links on each end, and use as timing marks.





5. Install the crankshaft sprocket.





6. Verify the crankshaft keyway is at the 11 o'clock position.





7. NOTE: Make sure the upper half of the timing chain is below the tensioner arm dowel and above the chain guide pin.

Position the upper end of the LH (inner) timing chain on the LH camshaft phaser and sprocket, aligning the timing mark on the outer flange of the camshaft phaser and sprocket with the single blue (marked) link on the chain.





8. 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 blue (marked) link on the chain.





9. Position the LH timing chain guide and install the bolt in 2 stages.
- Stage 1: Tighten to 10 Nm (89 lb-in).

- Stage 2: Tighten an additional 45 degrees.





10. Install the LH timing chain tensioner arm.





11. Position the LH timing chain tensioner and install the 2 bolts in 2 stages.
- Stage 1: Tighten to 10 Nm (89 lb-in).

- Stage 2: Tighten an additional 45 degrees.





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

13. Position the upper end of the RH (outer) timing chain on the RH camshaft phaser and sprocket, aligning the timing mark on the outer flange of the camshaft phaser and sprocket with the single blue (marked) link on the chain.





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





15. Position the RH timing chain tensioner arm on the dowel pin and the RH timing chain tensioner and install the 2 bolts in 2 stages.
- Stage 1: Tighten to 10 Nm (89 lb-in).

- Stage 2: Tighten an additional 45 degrees.





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

17. As a post-check, verify correct alignment of all timing marks.





18. Install the engine front cover. For additional information, refer to Engine Front Cover Service and Repair.
