The 1.5-liter 12-valve Hyundai G4EB engine was produced by the company from 1999 to 2012 and all this time was put on the very popular second-generation Hyundai Accent. In the European market, this unit was installed on the local version of Accent only before restyling.
In 1999, a pair of 1.5-liter engines debuted on the second generation Hyundai Accent: one with a 12-valve SOHC block head, and the other with a 16-valve DOHC block head. The power unit described here had a simple design: a cast-iron cylinder block, an aluminum 12-valve cylinder head equipped with hydraulic lifters and a timing belt drive. It also has distributed fuel injection and a dual coil ignition system.
The Alpha series includes: G4EA, G4EH, G4EE, G4EB, G4EC, G4ER, G4EK, G4ED.
The engine was installed on:
- Hyundai Accent 2 (LC) in 1999 – 2012.

Disadvantages of the Hyundai G4EB engine
- This is a simple and reliable power unit, which usually worries only about trifles: idle speed floats due to contamination of the throttle assembly, idle speed controller or injectors. High-voltage wires often break and the ignition coil cracks.
- Engines of the Alpha family are not famous for the highest resource of hydraulic lifters, they often fail and start knocking heavily on a run of 80 – 100 thousand km. In specialized forums, they blame the drop in lubricant pressure due to wear on the oil pump plunger.
- According to the regulations of the TagAZ plant, the timing belt in this engine changes every 50,000 km, but you can find reviews in which it burst even earlier. And always with bent valves. Together with the belt, it is very desirable to change the water pump, its resource is also small.
- On runs of more than 200 thousand kilometers, a small consumption of lubricant often appears and more often hardened valve stem seals that need to be replaced are to blame. When the oil burner exceeds a liter per 1000 km, it means that the oil scraper rings have already fallen.
- Also, owners often scold short-lived engine mounts, an unreliable starter, frequent lubricant leaks, or the appearance of a Check Engine due to a burnt muffler corrugation. And if the engine does not start, check the emergency fuel shutoff mechanism.
