- Confirm that the "Shoe" area of oil pump tensioner is protruding.
- Friction plate mark, timing chain color link (yellow or pink color) and crankshaft sprocket mark (yellow or pink color) should be matched.
The color of chain link should be matched with color of crank sprocket.
[Example]
Yellow (Chain) - Yellow (Crank Sprocket): OK
Pink (Chain) - Pink (Crank Sprocket): OK
Yellow - Pink: N.G
- Install the timing chain lower cover.
(Refer to Timing System - "TIMING CHAIN COVER ")
- Install the LH/RH cylinder heads.
(Refer to Cylinder Head Assembly - "CYLINDER HEAD ")
- Remove the SST from the timing chain guide and the timing chain tensioner arm.
- Install the LH/RH CVVT & camshafts.
(Refer to Cylinder Head Assembly - "CVVT & CAMSHAFT ")
- Install the timing chains to the CVVT sprockets.

[LH]
NOTE:- Make sure the crankshaft is at TDC position.
- Align the chain installation mark of the crankshaft sprocket and the timing mark of the chain link, and then install the chain.
NOTE:- To install the timing chain with no slack between each shaft (cam, crank), follow the below procedure.
- Crankshaft sprocket → Timing chain guide → Exhaust CVVT sprocket → Intake CVVT sprocket. (LH Bank)
- Crankshaft sprocket → Timing chain guide → Intake CVVT sprocket → Exhaust CVVT sprocket. (RH Bank)
- The timing mark of each sprockets should be matched with timing mark (orange or dark blue color link) of timing chain during installation.
- Install the LH/RH cam to cam guides (A).
Tightening Torque:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
[LH]
[RH]
- Confirm that the LH/RH timing chain tensioner is transport position by pressed below.
The hook must be around the pin.

- Install the LH timing chain guide bolt (B) and then the LH timing chain tensioner (A).
- Install the timing chain tensioner in the hole on the cylinder head by hand.
- Tighten the tensioner mounting bolts.

Timing chain guide bolt:
21.6 - 25.5 N.m (2.2 - 2.6 kgf.m, 15.9 - 18.8 lb-ft)
Timing chain tensioner bolt:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
NOTE:- Confirm identification mark "L" on the tensioner flange.
- The tensioner ratchet should be top-ward.
- Install the RH timing chain guide bolt (B) and then the RH timing chain tensioner (A).
- Install the timing chain tensioner in the hole on the cylinder head by hand.
- Tighten the tensioner mounting bolts.
Tightening Torque
Timing chain guide bolt:
21.6 - 25.5 N.m (2.2 - 2.6 kgf.m, 15.9 - 18.8 lb-ft)
Timing chain tensioner bolt:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
NOTE:- Confirm identification mark "R" on the tensioner flange and the gasket hole.
- The tensioner ratchet should be top-ward.
- Set tension of the LH/RH timing chain tensioner.
- LH Bank
- To set tension of the timing chain tensioner, push the timing chain tensioner arm outward to the end.
(Tensioner plunger moves back about 2-3 mm (0.0787-0.1181 in.))
- Tension of the timing chain tensioner will set after the lock is released.
If the tensioner tooth is visible, tension setting is completed.
- To set tension of the timing chain tensioner, push the timing chain tensioner arm outward to the end.
- RH Bank
- To set tension of the timing chain tensioner, push the timing chain tensioner arm outward to the end.

If the tensioner tooth is visible, tension setting is completed.
- To set tension of the timing chain tensioner, push the timing chain tensioner arm outward to the end.
- After setting tension of the LH, RH timing chain tensioner, check timing mark again.
- Make sure the chain installation mark of the sprocket and the timing marked chain links are aligned.
- Rotate the crankshaft 2 revolutions in regular direction (clockwise viewed from front), confirm the timing marks on the LH, RH intake and exhaust CVVT and the RH cylinder head upper surfaces are aligned.
- LH Bank
- After rotating the crankshaft 2 revolutions in regular direction (clockwise viewed from front), confirm the timing mark.NOTE:
- Always turn the crankshaft clockwise.
- Turning the crankshaft counter clockwise before building up oil pressure in the hydraulic timing chain tensioner may result in the chain disengaging from the sprocket teeth.
- Install the other parts reverse order of removal.
