Disadvantages of the Hyundai G4ED engine

  • This motor is reliable, and the main complaints are related to its unstable operation due to clogged nozzles, contamination of the throttle assembly or idle speed controller. Also often the culprit is the components of the ignition system: coils and their wires.
  • According to the official manual, the timing belt is recommended to be changed only once every 90 thousand km, but many cases of its breakage at a lower mileage are described, and usually the valves bend here. And don’t forget to renew the chain between the camshafts every two belt changes.
  • A small oil consumption for this engine may appear already at 150,000 km, and the reason is usually the wear of the valve stem seals and replacing them always helps. But if the engine consumes more than 1 liter per 1000 km, then most likely the rings have already been laid.
  • The weak points of the power unit also include eternally leaking gaskets and seals, short-lived engine mounts and hydraulic lifters, sometimes they knock hard already at 100,000 km. The search for the cause of poor starting should start with a fuel filter or a gasoline pump.
