Since the 1.8-liter Hyundai G4CN engine was a full replica of the Mitsubishi power unit with the 4G67 index by design, it was assembled under license in South Korea from 1992 to 1998. In many markets, this DOHC engine is most recognized for its premium Lantra.
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 mounted on:
- Hyundai Lantra 1 (J1) in 1992 – 1995;
- Hyundai Sonata 3 (Y3) in 1993 – 1998.

Disadvantages of the Hyundai G4CN engine
Keep an eye on the balancer belt’s condition; if it breaks, it falls beneath the timing belt.
A broken timing belt and a collision between valves and pistons are typically the results of all of this.
The speed begins to float as soon as the throttle and idle speed controller become dirty.
Here, cutting lubrication frequently results in hydraulic lifter failure.
Weak engine mounts and an unreliable fuel pump are other complaints from owners.
