Disadvantages of the Alfa Romeo AR16105 engine

  • The main problems of this motor are associated with suction through cracked pipes.
  • In addition to floating engine speed, this leads to system airing and overheating.
  • Also, the engine often overheats due to thermostat or water pump failures.
  • From bad oil or its rare replacement, the liners often turn.
  • Change the timing belt every 60,000 km, as when it breaks, the valves bend here.
