Disadvantages of the Geely JLH-4G20TD engine

  • No serious complaints about this engine were found on specialized forums;
  • Like all direct injection units, it is prone to carbon deposits on the valves;

  • It is also important to monitor the condition of the timing belt, since if it breaks, the valves bend.
