Disadvantages of the C9DA/C9DB/C9DC engine

  • This diesel engine is not like its predecessors and, with good fuel quality, runs for a long time;
  • Low-quality diesel fuel quickly affects the performance of high-pressure fuel pumps and injectors;
  • The cause of sudden traction failures is usually a severely clogged fuel filter;
  • Lubrication leaks often form at the junction of the upper and lower parts of the cylinder block;
  • If the engine is unstable, it is worth inspecting the corrugations of the intercooler air duct.
