SPECIAL TOOL(S)
| Tool, Camshaft Holding 303-1248 |
NOTE:
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 can cause engine failure.
NOTE:
The engine comes equipped with either a roller primary timing chain or an inverted tooth primary timing chain. The roller timing chain engine comes equipped with either a composite RH timing chain guide requiring the timing chain to ride on the outer side of the guide or a stamped steel RH timing chain guide requiring the timing chain to ride on the inner side of the guide. All roller timing chain engine replacement RH timing chain guides will be the stamped steel design.

- Install the RH secondary timing chain tensioner and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Assemble the RH Variable Camshaft Timing (VCT) assembly, the RH exhaust camshaft sprocket and the RH secondary timing chain.
- Align the colored links with the timing marks.
- Position the RH secondary timing assembly onto the camshafts.
- Install 2 new bolts and the original washer. Tighten in 4 stages.
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Loosen one full turn.
- Stage 3: Tighten to 10 Nm (89 lb-in).
- Stage 4: Tighten 90 degrees.
- Remove the lockpin from the RH secondary timing chain tensioner.
- Install the LH secondary timing chain tensioner and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Assemble the LH VCT assembly, the LH exhaust camshaft sprocket and the LH secondary timing chain.
- Align the colored links with the timing marks.
- Position the LH secondary timing assembly onto the camshafts.
- Install 2 new bolts and the original washer. Tighten in 4 stages.
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Loosen one full turn.
- Stage 3: Tighten to 10 Nm (89 lb-in).
- Stage 4: Tighten 90 degrees.
- Remove the lockpin from the LH secondary timing chain tensioner.
Engines equipped with an inverted tooth timing chain
- Install the crankshaft timing chain sprocket.
- Install the upper LH primary timing chain guide and the bolt.
- Tighten to 10 Nm (89 lb-in).
- Install the primary timing chain with the colored links aligned with the timing marks on the VCT assemblies and the crankshaft sprocket.
- Install the lower LH primary timing chain guide and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Install the primary timing chain tensioner arm.
- 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 and install a suitable lockpin.
- Install the primary tensioner and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Remove the lockpin.
- As a post-check, verify correct alignment of all timing marks.
- There are 48 links between the RH intake VCT assembly colored link (1) and the LH intake VCT assembly colored link (2).
- There are 35 links between the LH intake VCT assembly colored link (2) and the 2 crankshaft sprocket colored links (3).

NOTE:
RH shown in illustration, LH similar.
NOTE:
During removal, the O-ring seal may remain on the cylinder head. If so, remove the O-ring seal from the cylinder head, inspect the seal (replace as necessary) and install the O-ring seal on the VCT housing.
NOTE:
Make sure the dowels on the Variable Camshaft Timing (VCT) housing are fully engaged in the cylinder-head prior to tightening the bolts. Failure to follow this process will result in severe engine damage.
