Disadvantages of the Hyundai G4CN engine

  • Monitor the condition of the balancer belt, if it breaks, it falls under the timing belt.
  • All this usually ends with a broken timing belt and a meeting of valves with pistons.
  • The throttle and idle speed controller also get dirty very quickly, and then the speed starts to float.
  • Saving on lubrication here often ends with the failure of hydraulic lifters.
  • Owners also complain about an unreliable fuel pump and weak engine mounts.
