Removal

NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan may cause engine failure.

1. Remove the engine front cover. For additional information, refer to Engine Front Cover in this section.

2. Rotate the crankshaft clockwise and align the timing marks on the intake Variable Camshaft Timing (VCT) assemblies as shown.

3. Remove the 3 bolts and the LH valve train oil tube.

4. NOTE: The Camshaft Holding Tool will hold the camshafts in the Top Dead Center (TDC) position.

   Install the Camshaft Holding Tool onto the flats of the LH camshafts.

5. Remove the 3 bolts and the RH valve train oil tube.

6. NOTE: The Camshaft Holding Tool will hold the camshafts in the TDC position.

   Install the Camshaft Holding Tool onto the flats of the RH camshafts.

NOTE: The following 3 steps are for primary timing chains that the colored links are not visible.

7. Mark the timing chain link that aligns with the timing mark on the LH intake VCT assembly as shown.

8. Mark the timing chain link that aligns with the timing mark on the RH intake VCT assembly as shown.

9. NOTE: The crankshaft sprocket timing mark should be between the 2 colored links.

   Mark the 2 timing chain links that align with the timing mark on the crankshaft sprocket as shown.

10. Remove the 2 bolts and the primary timing chain tensioner.

11. Remove the primary timing chain tensioner arm.

12. Remove the 2 bolts and the lower LH primary timing chain guide.
    • Position the timing chain aside.

14. Remove the 2 bolts and the oil pump screen and pickup tube.
    • Discard the O-ring seal.

15. Remove the 3 bolts and the oil pump.

Installation

1. Install the oil pump and the 3 bolts.
   • Tighten to 10 Nm (89 lb-in).

2. Using a new O-ring seal, install the oil pump screen and pickup tube and the 2 bolts.
   • Tighten to 10 Nm (89 lb-in).

3. Install the crankshaft timing chain sprocket with timing dot mark out.

4. NOTE: It may be necessary to rotate the camshafts slightly, to align the timing marks.

   Position the primary timing chain with the colored links aligned with the timing marks on the VCT assemblies and the crankshaft sprocket.

5. Install the lower LH primary timing chain guide and the 2 bolts.
   • Tighten to 10 Nm (89 lb-in).

6. Install the primary timing chain tensioner arm.

7. Reset the primary timing chain tensioner.
   • Release the ratchet detent.
   • Using a soft-jawed vise, compress the ratchet plunger.
   • Align the hole in the ratchet plunger with the hole in the tensioner housing.
   • Install a suitable lockpin.

8. NOTE: It may be necessary to rotate the camshafts slightly to remove slack from the timing chain to install the tensioner.

   Install the primary tensioner and the 2 bolts.
   • Tighten to 10 Nm (89 lb-in).
   • Remove the lockpin.

9. As a post-check, verify correct alignment of all timing marks.
   • There are 48 links in between the RH intake VCT assembly colored link (1) and the LH intake VCT assembly colored link (2).
   • There are 35 links in between LH intake VCT assembly colored link (2) and the 2 crankshaft sprocket links (3).
