Disadvantages of the XUD11A engine

  • This very reliable and almost omnivorous diesel engine has a resource of under 500,000 km;
  • The low location of the expansion tank brings owners a lot of problems;
  • At the slightest drop in the level of antifreeze, the motor overheats and breaks through the gasket;
  • Change the fuel filter more often, as the Lucas injection pump is difficult to repair;
  • This filter must be replaced carefully, it is very easy to break its glass;
  • Hydraulic lifters do not tolerate cheap oil and can knock up to 100,000 km;
  • The network describes cases of loss of fore-chambers on runs of more than 300 – 400 thousand km.
