Additional Notes

  • The Alfa Romeo 166 936 power steering system holds 1.4 liters of fluid across all listed engine variants, from the 2.0 TB and 2.0 TS four-cylinders to the 2.4 JTD and 2.4 JTDm 20V diesels and the 2.5, 3.0, and 3.2 V6 petrol engines. A uniform reservoir capacity across such a range of engine displacements and configurations points to a shared hydraulic steering rack assembly rather than engine-specific hardware.
  • The 1.4-liter figure represents the total system capacity of the power steering circuit, covering the reservoir, pump, and lines. In practice, a routine fluid service typically recovers less than the full system volume, with the full 1.4 liters relevant primarily when the system is drained completely during a pump or rack replacement.
  • All seven variants carry a 20,000 km check interval under normal use conditions. A fluid check at this interval does not necessarily mean a full fluid exchange is due; rather, 20,000 km is the point at which fluid level and condition are assessed, with replacement scheduled separately if degradation is observed.
  • The normal use condition applied to all rows refers to standard on-road driving without the elevated stress cycles associated with severe use classifications, such as frequent low-speed maneuvering, towing, or extreme temperature exposure. Power steering fluid under normal conditions degrades more slowly, which aligns with the relatively long 20,000 km check interval specified here.
  • The 2.5 V6 variant covers the 2003-2005 period, a shorter production window than the 2003-2007 span shared by most other listed engines. Despite the shorter model run, the power steering capacity and check interval remain identical to the rest of the lineup.
  • The 3.2 V6 enters the specification table from 2004, one year later than the other engines in the 2003-2007 group. Even with the later introduction, the power steering specifications align exactly with those of the longer-running variants, indicating no revision to the hydraulic system was made when the 3.2 V6 was added to the range.
