24350-3C100 CVVT Camshaft Gear | Hyundai 3.3 3.8 V6 Intake Cam Phaser
24350-3C100 CVVT Camshaft Gear is the intake-side camshaft phaser used in Hyundai and Kia Lambda V6 engines. The unit replaces OE numbers 24350-3C100 and 24350-3CAC0 and is installed on engines including G6DA and G6DB found in vehicles such as Hyundai Genesis, Grandeur, ix55, Sonata V and Kia Sorento or Sedona equipped with 3.3L–3.8L V6 DOHC engines.
Within the variable valve timing system, the 24350-3C100 CVVT Camshaft Gear adjusts the intake camshaft angle relative to the crankshaft using hydraulic oil pressure. By advancing or retarding the cam timing, the system allows the engine to optimise combustion efficiency across different RPM ranges. This component is often referenced in aftermarket catalogues as a Hyundai 3.3 3.8 V6 camshaft adjuster or Hyundai VVT cam phaser intake for the Lambda engine platform.
In workshop diagnostics, failure of the G6DB engine cam phaser or related G6DB G6DA engine VVT gear can lead to cam timing deviation, cold start rattle or engine fault codes associated with intake camshaft position control. For repair work involving timing chain service or camshaft timing recalibration, replacing the intake cam phaser together with related timing components is common practice.

Function of the Intake CVVT Camshaft Gear
In the Lambda V6 engine architecture, the intake cam phaser sits between the timing chain sprocket and the intake camshaft.
The Hyundai VVT cam phaser intake performs several tasks:
- Adjusts intake valve opening timing during engine load changes
- Improves combustion efficiency at low and mid RPM
- Stabilises idle by retarding intake timing when required
- Works with the oil control valve (OCV) to regulate camshaft advance
Hydraulic oil pressure is directed into internal chambers inside the 24350-3C100 24350-3CAC0 intake camshaft actuator, rotating the camshaft relative to the sprocket. The ECU continuously modifies this position based on load, RPM and throttle demand.
Typical Failure Symptoms in Workshop Diagnostics
When a CVVT cam phaser replacement Kia Sorento 3.3 G6DB becomes necessary, technicians usually observe several symptoms.
Common workshop findings include:
- Cold start rattling noise from the timing chain area
- Engine fault codes such as camshaft correlation errors
- Irregular idle or hesitation during acceleration
- Camshaft angle not matching commanded value in scan data
- Oil contamination affecting the phaser locking mechanism
In engines where timing chains or guides are already worn, the G6DA G6DB G6DG engine code VVT timing gear is frequently replaced together with:
- timing chain
- chain tensioner
- chain guides
- oil control valve
This ensures stable cam timing after the repair.
Manufacturing and Quality Control
Production of the 24350-3C100 CVVT Camshaft Gear requires precise control of internal hydraulic passages and cam phaser tolerances. Every batch undergoes rotation and hydraulic response testing to confirm that the Hyundai 3.3 3.8 V6 camshaft adjuster reacts correctly to oil pressure changes during simulated engine operation. For B2B customers such as distributors and engine rebuilders:
- factory direct supply from China
- stable batch production for consistent fitment
- neutral packaging or private label packaging available
- export supply for European aftermarket distribution networks
FAQ
1. What engines use the 24350-3C100 CVVT Camshaft Gear?
The component is used on Hyundai and Kia V6 engines including G6DA 3.8L and G6DB 3.3L platforms.
2. Is the 24350-3C100 an intake or exhaust cam phaser?
This OE number refers to the intake camshaft CVVT gear.
3. Can 24350-3C100 replace 24350-3CAC0?
Yes. In many aftermarket catalogues 24350-3C100 and 24350-3CAC0 intake camshaft actuator are listed as interchangeable replacement numbers.
4. What causes failure of a Hyundai 3.3 3.8 V6 camshaft adjuster?
Typical causes include oil contamination, worn internal locking pins, or insufficient oil pressure affecting hydraulic actuation.
5. What diagnostic codes are associated with a failing VVT cam phaser?
Fault codes often involve camshaft timing deviation or cam/crank correlation issues detected by the ECU.
6. How can technicians verify a cam phaser malfunction?
Using a diagnostic scanner to compare commanded cam angle versus actual cam angle is a common method.
7. Is this part suitable for engine rebuilders?
Yes. Engine rebuilders often replace the 24350-3C100 intake camshaft gear for Hyundai GENESIS 3.3L during Lambda V6 timing system overhaul.
8. How long does a CVVT cam phaser typically last?
Service life depends heavily on oil quality and maintenance intervals.
