Sirius family: 1.6 L – G4CR; 1.8 L – G4CN, G4CM, G4JN; 2.0 L – G4CP, G4JP; 2.4 L – G4JS, G4CS.
The engine was installed on:

Disadvantages of the Hyundai G4CN engine
- Monitor the condition of the balancer belt, if it breaks, it falls under the timing belt.
- All this usually ends with a broken timing belt and a meeting of valves with pistons.
- The throttle and idle speed controller also get dirty very quickly, and then the speed starts to float.
- Saving on lubrication here often ends with the failure of hydraulic lifters.
- Owners also complain about an unreliable fuel pump and weak engine mounts.
