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.
