24350-2B010 VVT Camshaft Adjuster | Hyundai Kia G4FA G4FC Engine Part

Technical Specifications

Structural Characteristics of the Cam Phaser

The 1.4L 1.6L G4FA G4FC engine VVT sprocket integrates several functional sections:

1. External Timing Gear

• 46-tooth sprocket
• synchronises the camshaft with the timing chain
• transmits rotational load from crankshaft to intake camshaft

2. Hydraulic Phase Chamber

• internal rotor-stator structure
• oil pressure shifts camshaft phase angle
• controlled by the engine ECU through the oil control valve

3. Locking Pin Mechanism

• holds the cam in default position during engine start
• prevents timing fluctuation at low oil pressure

In the Hyundai 1.6 VVT Cam Phaser configuration, oil flow through the adjuster determines whether the camshaft timing is advanced or retarded relative to crankshaft rotation.

Typical Service Scenarios

Workshops generally encounter this Hyundai Kia G4FA G4FC Engine Part in the following situations:

• Timing Chain Service: During chain kit replacement, the intake cam gear is often inspected or replaced to ensure correct phasing.
• Cold Start Rattle: Wear inside the phaser chamber or locking mechanism may cause a metallic rattle for a few seconds after start-up.
• Timing Deviation Fault Codes: Fault codes related to camshaft timing advance or retard can appear if the Intake camshaft timing gear OE 24350-2B010 243502B000 loses hydraulic control accuracy.
• Engine Rebuild Work: Engine rebuilders frequently replace the 24350-2B010 VVT Camshaft Adjuster during cylinder head rebuild or camshaft replacement.

Technical Background — How the CVVT System Works on G4FA / G4FC

On the Gamma engine, CVVT (Continuously Variable Valve Timing) is intake-side only. The system uses a single oil control valve (OCV) bolted to the cylinder head, which directs engine oil into either the advance or retard chamber of the camshaft adjuster hub.

At idle and low loads, the ECU commands the OCV to hold timing in the retarded position — this reduces overlap between intake and exhaust valve events, keeping idle smooth. Under moderate load and mid-range RPM, timing advances 20–40° to maximise cylinder filling and improve torque. At high RPM or light load (overrun), timing is progressively retarded again to limit pumping losses.

When the adjuster wears internally or becomes contaminated with sludge, the vane rotor cannot hold the commanded position. The ECU detects the cam angle deviation via the camshaft position sensor and logs one or more of the following codes:

• P0011 — Camshaft position, intake timing over-advanced (Bank 1)
• P0014 — Camshaft position, exhaust timing over-advanced (Bank 1) (sometimes logged as the OCV attempts to compensate)
• P0021 — Camshaft position timing over-advanced (Bank 2, where applicable)

A cold-start metallic rattle that disappears within 5–10 seconds of warm-up is a near-classic indicator of a worn CVVT hub on this engine family. Do not confuse this with timing chain stretch — both can occur simultaneously, and a chain that has jumped teeth cannot be corrected by replacing the cam adjuster alone.

FAQ

1. What engines use the 24350-2B010 VVT Camshaft Adjuster?

It is primarily installed in Hyundai and Kia petrol engines G4FA (1.4L) and G4FC (1.6L) with CVVT variable valve timing systems.

2. Is 243502B000 interchangeable with 24350-2B010?

Yes. In most catalogues 24350-2B010 cross reference 243502B000 represents the same intake cam phaser design.

3. Is this an intake or exhaust cam phaser?

The 24350-2B010 VVT Camshaft Adjuster is used on the intake camshaft side.

4. What vehicles commonly use this Hyundai Kia VVT Camshaft Phaser?

Typical models include Hyundai i20, i30, Accent and Kia Ceed, Rio and Soul equipped with G4FA or G4FC engines.

5. When should the Hyundai 1.6 VVT Cam Phaser be replaced?

Replacement is usually considered when cold start rattle occurs, when cam timing codes appear, or during a timing chain overhaul.

6. Does this part include the camshaft?

No. The 24350-2B010 VVT Camshaft Adjuster is only the camshaft phasing gear installed on the camshaft nose.

7. Can a worn 1.4L 1.6L G4FA G4FC engine VVT sprocket affect engine performance?

Yes. Incorrect cam timing can reduce efficiency, cause rough idle, or trigger engine management fault codes.

8. Do both intake and exhaust cams use the same phaser in G4FA engines?

No. Intake and exhaust phasers may differ depending on the specific engine version.

9. What packaging is used for export?

Parts ship in individual neutral boxes with OE number labelling, suitable for onward distribution or workshop shelf storage.

10. How long does delivery typically take to Europe?

Lead time depends on order volume and current production schedule. Most trade orders ship within 7–14 working days once confirmed.
