Hürlimann Prince

Power steering fluid capacity & service interval

Hürlimann Prince uses power steering fluid with a capacity of 21 liters. Service intervals include checking every 150 hours and changing every 1200 hours. The data covers 2 configurations.

Additional Notes

  • The Hürlimann Prince shares its power steering fluid with the transaxle and hydraulic system, meaning a single 21-liter reservoir serves all three functions simultaneously across both the 325 and 335 variants.
  • A 21-liter capacity is notably large for a power steering circuit and reflects the integrated nature of the system, where the fluid volume must support hydraulic demands beyond steering alone.
  • The check interval is set at every 150 hours of operation under normal use conditions, which in hour-based service schedules is a relatively short monitoring cycle relative to the full change interval.
  • The change interval of 1,200 hours under normal use conditions represents a ratio of 8:1 between the check and change intervals, indicating that fluid condition is monitored frequently before a full drain and refill is required.
  • Both the Prince 325 and Prince 335 from 1997-2002 carry identical capacity and service interval figures, with 21 liters, a 150-hour check, and a 1,200-hour change applying equally to each model.
