The company produced the 1.5-liter 16-valve Hyundai G4EC engine from 1999 to 2012 and installed it on the second generation Hyundai Accent and its licensed counterparts. In most other countries, this engine was installed on local versions of the Accent only before restyling.
In 1999, two 1.5-liter power units appeared on the second generation of the Accent model, which differed in block heads: one 12-valve SOHC, and the second 16-valve DOHC. The G4EC motor had a cast-iron block, an aluminum 16-valve head with hydraulic lifters, and a combined timing belt and short chain between the camshafts. It also had multiport fuel injection and a dual coil ignition system.
On European and Korean versions of the Accent, this engine was installed only until the restyling of 2003, but in some other markets it was installed until the end of the model’s production in 2012.
Alpha family: G4EA, G4EH, G4EE, G4EB, G4EC, G4ER, G4EK, G4ED.

Disadvantages of the Hyundai G4EC engine
- This motor does not have any special weak points, it worries mainly about trifles: engine speed floats due to contamination of the throttle, idle speed controller or injectors, and it often starts to triple due to a cracked ignition coil or broken wires.
- A signature feature of Alpha engines is the modest resource of hydraulic lifters. They prefer good oil and its frequent replacement, otherwise they will knock up to 100 thousand kilometers. Some attribute the wear of the oil pump plunger and a drop in lubricant pressure to the cause.
- In the Accent TagAZ manual, it is prescribed to replace the timing belt every 50 thousand kilometers, however, you can find reviews of those who had it torn before, and the valve is bent here. Once every 100,000 km, the chain between the camshafts also needs to be replaced, it also does not go for a long time.
- After 200,000 km, a small amount of lubricant often appears and it grows with mileage. Most often, the cause is hardened valve stem seals and replacement usually helps, but if not, then the rings are stuck and the unit will need more expensive repairs.
- You can also find complaints about short-lived attachments and engine mounts, regular lubricant leaks and the appearance of a Check Engine due to a burnt muffler corrugation. If the engine does not start, it is worth checking the emergency fuel shut-off system.
