24370-2G000 VVT Camshaft Gear for Hyundai Kia 2.0L 2.4L Exhaust CVVT Assembly
The 24370-2G000 VVT Camshaft Gear is the exhaust camshaft phasing unit used in Hyundai and Kia Theta II petrol engines. Installed on 2.0L G4KD and 2.4L G4KE platforms, the component adjusts exhaust valve timing through the hydraulic CVVT system to match engine load and speed conditions.
Within the timing system, the 24370-2G000 Camshaft Gear operates together with the oil control valve and ECU to rotate the exhaust camshaft relative to the crankshaft position. Accurate cam phase control improves torque delivery at mid-range RPM while maintaining stable combustion and emission compliance.
The 24370-2G000 CVVT Assembly Exhaust is widely used in vehicles such as Hyundai Tucson, Sonata and Santa Fe, as well as Kia Optima, Forte and Sorento models equipped with 2.0L or 2.4L DOHC petrol engines. In service environments, this 24370-2G000 Camshaft Phaser is commonly replaced during timing chain repair or when camshaft timing fault codes appear.

Structure of the 24370-2G000 Camshaft Phaser
Understanding the internal mechanism of the 24370-2G000 Camshaft Gear helps technicians diagnose common timing issues.
- Hydraulic Vane Chambers: Engine oil pressure fills advance and retard chambers to rotate the camshaft phase.
- Rotor and Stator Assembly: Multiple sealed chambers allow controlled rotation between camshaft and timing sprocket.
- Mechanical Lock Pin: During engine start-up, the locking pin keeps the camshaft in base timing position until oil pressure stabilises.
- Timing Alignment Points: Marks on the sprocket correspond with the timing chain installation reference used during engine assembly.

FAQ
1. How to confirm if the 24370-2G000 VVT Camshaft Gear is the correct part for the engine?
Check engine code first (G4KD or G4KE). Then verify OE number on the original cam phaser or via VIN-based parts catalogue. This 24370-2G000 Camshaft Gear is strictly used on the exhaust side of Theta II engines.
2. What is the difference between intake and exhaust CVVT units on these engines?
The intake and exhaust phasers are not interchangeable. The 24370-2G000 CVVT Assembly Exhaust has a different internal oil flow design and phase angle range compared to the intake side unit.
3. Can a faulty cam phaser cause timing chain noise?
Yes. When internal wear increases clearance, the 24370-2G000 Camshaft Phaser may create a knocking or rattling noise, especially during cold start before oil pressure stabilises.
4. What are the most common fault codes linked to this part?
Typical OBD codes include:
- P0014 – Exhaust camshaft timing over advanced
- P0011 – Camshaft timing performance issue
- P0010 – Camshaft actuator circuit malfunction
These codes often appear when the 24370-2G000 G4KD G4KE CVVT assembly exhaust cannot hold or reach the commanded position.
5. Does the 24370-2G000 exhaust camshaft sprocket for Hyundai Kia 2.0L 2.4L require priming before installation?
It is good workshop practice to lubricate the internal chamber with clean engine oil before installation to reduce dry start wear.
6. Is this part suitable for turbocharged engines?
The Exhaust CVVT Assy 24370-2G000 compatible with 2.4L DOHC engines is mainly used on naturally aspirated engines, but similar phaser structures are used in some 2.0L turbo variants. Always verify via OE number.
7. Can low-quality aftermarket phasers cause repeat faults?
Yes. Poor machining tolerance or weak sealing inside the vane chamber can result in:
- Inaccurate cam positioning
- Persistent fault codes
- Short service life
This is why many buyers focus on OEM quality replacement when sourcing the 24370-2G000 Camshaft Phaser.
8. What is the typical lead time for the 24370-2G000 VVT Camshaft Gear?
For standard orders, production lead time is usually 7–15 working days depending on order quantity. For repeat customers ordering the 24370-2G000 Camshaft Gear, partial stock allocation may shorten delivery time.
9. Do you keep stock in Europe?
Currently, the 24370-2G000 CVVT Assembly Exhaust is supplied directly from the manufacturing facility. There is no fixed warehouse stock in Europe, but regular export batches are arranged for distributors.
