The 1.8-liter 16-valve Hyundai G4GB engine was produced by the company from 2001 to 2010 and was installed on such popular models of the Korean concern as Matrix, Elantra and Cerato. There were two different modifications of the unit: 122 hp / 162 Nm and 132 hp / 166 Nm.
In 2001, a 1.8-liter unit debuted as part of the second generation of the Beta family. It was a fairly typical engine for that time with distributed fuel injection, an in-line cast-iron cylinder block, an aluminum 16-valve cylinder head without hydraulic lifters and a combined timing drive from a belt and a short chain between two camshafts.
Unlike the 2.0-liter brother in the line, this unit did not have a version with a phase regulator and existed in two modifications of different power, which, in fact, were distinguished only by the firmware of the control unit.
Beta family: G4GR, G4GB, G4GM, G4GC, G4GF.

Disadvantages of the Hyundai G4GB engine
- This is a simple design and very reliable unit, and most of the complaints are related to the unstable operation of the engine and, in particular, floating idle speeds. As with many other motors, the main cause is a dirty throttle or idle speed controller.
- Another weak point of this motor is a very capricious ignition system: ignition coils and high-voltage wires and contacts on candles are often changed here.
- According to the manual, the timing belt changes every 60,000 km and such a short schedule is not without reason, since breaks at high mileage occur regularly and usually with valve bending.
- Also here, oil constantly climbs from under the valve cover and the engine mounts serve little. And do not forget to adjust the thermal clearance of the valves, since there are no hydraulic compensators.
