Set No.1 cylinder to top dead center (TDC)/compression.
Turn the crankshaft pulley clockwise and align its groove with the timing mark "T" of the lower timing chain cover.
Check that the mark (A) of the camshaft timing sprockets are in straight line on the cylinder head surface as shown in the illustration. If not, turn the crankshaft clockwise one revolution (360°).
Do not rotate engine counterclockwise.
Remove the timing chain cover.
(Refer to Timing System - "Timing Chain Cover")
Before removing the timing chain, mark the RH/LH timing chain with an identification based on the location of the sprocket because the identification mark on the chain for TDC can be erased.

Install a set pin after compressing the LH timing chain tensioner.
Remove the LH cam to cam guide (A).
Remove the LH timing chain auto tensioner (A) and LH timing chain tensioner arm (B).
Remove the LH timing chain guide (A) and LH timing chain (B).
Remove the crankshaft sprocket (A). (LH camshaft drive).
Remove the tensioner adapter assembly (A).
Check the camshaft sprocket and crankshaft sprocket for abnormal wear, cracks, or damage. Replace as necessary
Inspect the tensioner arm and chain guide for abnormal wear, cracks, or damage. Replace as necessary.
Check that the tensioner piston moves smoothly when the ratchet pawl is released with thin rod.
The key (A) of crankshaft should be aligned with the timing mark (B) of timing chain cover. As a result of this, the piston of No.1 cylinder is placed at the top dead center on compression stroke.
Install the tensioner adapter assembly (A).
Install the crankshaft sprocket (A). (LH camshaft drive).
Install the LH timing chain guide (A) and LH timing chain (B).
Tightening torque :
19.6 ~ 24.5 N.m (2.0 ~ 2.5 kgf.m, 14.5 ~ 18.1 lb-ft)
To install the timing chain with no slack between each shaft (cam, crank), follow the below procedure.
Crankshaft sprocket → Timing chain guide → Exhaust camshaft sprocket → Intake camshaft sprocket.
The timing mark of each sprockets should be matched with timing mark (color link) of timing chain at installing timing chain.
Install the LH timing chain auto tensioner (A) and LH timing chain tensioner arm (B).
Tightening torque
A : 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
B : 18.6 ~ 21.6 N.m (1.9 ~ 2.2 kgf.m, 13.7 ~ 15.9 lb-ft)
Install the LH cam to cam guide (A).

9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Install the crankshaft sprocket (A) (O/P & RH camshaft drive).
Install the oil pump chain sprocket (A) and oil pump chain (B).
Tightening torque :
18.6 ~ 21.6 N.m (1.9 ~ 2.2 kgf.m, 13.7 ~ 15.9 lb-ft)

Pull out the pins of hydraulic tensioner (LH & RH).
After rotating the crankshaft 2 revolutions in regular direction (clockwise viewed from front), confirm the timing mark.
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 timing chain cover.
(Refer to Timing System - "Timing Chain Cover")
Install all other parts in reverse order of removal.
Refill engine oil.
Clean the battery posts and cable terminals with sandpaper. Assemble and then apply grease to prevent corrosion.
Inspect for fuel leakage.
After assembling the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for approximately two seconds and fuel line pressurizes.
Repeat this operation two or three times, then check for fuel leakage at any point in the fuel lines.
Refill radiator and reservoir tank with engine coolant.
Bleed air from the cooling system.
Start engine and let it run until it warms up. (Until the radiator fan operates 3 or 4 times.)
Turn Off the engine. Check the level in the radiator, add coolant if needed. This will allow trapped air to be removed from the cooling system.
Put radiator cap on tightly, then run the engine again and check for leaks.
