Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Repair Procedures: Installation
- The TDC marks of the intake and exhaust CVVT sprockets are slightly turned from the TDC position as shown when the timing chain is removed.
- Turn the crankshaft clockwise (about 2-3 pitches) from the TDC position (the dowel pin (A) of crankshaft is about 3° with the engine vertical line) as rotation of the intake CVVT sprocket from the TDC position.
- Install the timing chain guide (A).
Tightening torque:
18.6-22.6 N.m (1.9-2.3 kgf.m, 13.7 - 16.6 lb.ft)
- Install the timing chain.
Crankshaft sprocket - Timing chain guide - Intake CVVT sprocket - Exhaust CVVT sprocket
- Install the timing chain with no slack between the crankshaft sprocket and the intake CVVT sprocket.NOTE: The timing marks of each sprocket should be matched with timing marks (color link) of timing chain when installing the timing chain.
- Install the timing chain on the exhaust CVVT sprocket with no slack while turning the CVVT assembly clockwise.NOTE:
- The timing mark of the exhaust CVVT sprocket should be matched with timing mark (color link) of timing chain when installing the timing chain.
- Press down the timing chain links on the exhaust CVVT sprocket to prevent the sprocket from spinning.
- Install the timing chain with no slack between the crankshaft sprocket and the intake CVVT sprocket.
- Install the timing chain tensioner arm (A).
Tightening torque:
18.6 - 22.6 N-m (1.9 - 2.3 kgf-m, 13.7 - 16.6 lb-ft)
- Install the timing chain auto tensioner (A) and remove the stopper pin (B).
Tightening torque:
9.8 - 11.8 N-m (1.0 - 1.2 kgf-m, 7.2 - 8.7 lb-ft)
NOTE: When reinstall the tensioner, always use new tensioner. - After rotating crankshaft 2 revolutions in regular direction (clockwise viewed from front), confirm that the TDC marks on the intake and exhaust CVVT sprockets are aligned with the top surface of cylinder head.
- Install the other parts reverse order of removal.NOTE:
- Refill engine with engine oil.
- Clean battery posts and cable terminals and assemble.
- 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 line.2

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
