Additional Notes

  • The Hürlimann XF 55 Spirit carries the smallest cooling system capacity across the XF Spirit range at 11 liters, while all other listed configurations hold 12 liters. A larger cooling system capacity generally reflects a greater engine displacement or higher thermal load requirement.
  • The XF 55 Spirit (up to serial number ZKDCN50200RH10001, 2015-2020), XF 65 Spirit (up to ZKDCN60200RH10001, 2015-2020), XF 75 Spirit (up to ZKDCN70200RH10001, 2015-2020), and XF 80.4 Spirit (up to ZKDCN80200RH10001, 2015-2020) all share a coolant change interval of 2000 hours or 24 months under normal use conditions, whichever comes first.
  • Stage 3B and Stage 5 configurations of the XF 70 Spirit, XF 80 Spirit, and XF 80.4 Spirit carry a longer coolant change interval of 2400 hours or 24 months, compared to the 2000-hour interval on the earlier serial number variants of the same model family.
  • The 24-month time-based interval appears across all listed configurations regardless of engine stage, meaning calendar time serves as a parallel drain trigger alongside the hour-based threshold in every case.
  • Stage 3B and Stage 5 variants of the XF 70 Spirit, XF 80 Spirit, and XF 80.4 Spirit include a 10-hour coolant check interval, a short-cycle inspection point not present in the 2015-2020 serial number variants. A 10-hour check interval is typically associated with verifying coolant level and condition shortly after initial operation or a service event.
  • The XF 70 Spirit Stage 3B (from serial number ZKDEZ10200RH50001, starting 2018) and the XF 70 Spirit Stage 5 (from serial number ZKDHA50200RH50001, starting 2021) share identical cooling system specifications: 12-liter capacity, a 10-hour check, and a 2400-hour or 24-month change interval under normal use conditions.
  • The same alignment in specifications applies to the XF 80 Spirit Stage 3B (from ZKDEZ50200RH50001, starting 2018) and Stage 5 (from ZKDHA90200RH50001, starting 2021), both specifying 12 liters, a 10-hour check, and the 2400-hour or 24-month change interval.
