Disadvantages of the Hyundai G6DN engine

  • So far, the main problems here are associated with the formation of carbon deposits on the intake valves.
  • This is a pretty hot engine, so keep an eye on the condition of the cooling system.
  • Let’s see how long the timing chains will last, the resource was modest on the predecessor.
  • Do not forget about adjusting the valve clearances, as it does not have hydraulic lifters.
