  • System, power steering/brake booster/levelling
  • Use: Normal
  • Capacity 5,4 liter

Additional Notes

  • The Citroën SM's hydraulic system capacity of 5.4 liters reflects a unified circuit shared across power steering, brake boosting, and ride-height leveling functions rather than a dedicated steering-only reservoir.
  • A 5.4-liter fill volume is notably large for what is conventionally categorized as a power steering service, and signals that a full drain-and-refill procedure addresses the entire interconnected hydraulic network simultaneously.
  • The SM 2.7 V6 (1970-1972) carries a single capacity figure with no differentiation between a service fill and an overhaul fill, indicating the 5.4-liter value applies as the standard working volume of the system.
  • The specification is listed under normal use conditions, meaning the 5.4-liter capacity and associated service parameters are not adjusted for severe operating environments in the data provided.
