Fenwick Forklift trucks, diesel (023 series)

Coolant capacity & service interval

Fenwick Forklift trucks, diesel (023 series) use coolant with a capacity range of 50 to 60 liters. Service intervals consist of a 10 hour check and a 2000 hour change. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The H320 and H370 variants, both fitted with the Scania DS11 66A engine, share an identical cooling system capacity of 50 liters, while the H420, H450, and H520 variants each carry a larger 60-liter capacity.
  • The 10-liter difference between the lower and upper capacity groups reflects the greater thermal mass requirements of the configurations running at higher load ratings, as larger working capacities in industrial lift equipment typically generate more heat under sustained operation.
  • The Fenwick Forklift trucks, diesel (023 series) H420 uses the Scania DS11 66A engine and shares the 60-liter cooling system capacity with the H450 and H520, despite the latter two running the DS11 59A engine variant instead.
  • All five configurations share a coolant check interval of every 10 hours of operation under normal use conditions, which in industrial forklift service typically corresponds to daily or shift-based inspection routines.
  • The coolant change interval is set at 2000 hours across all five configurations under normal use conditions, a figure that in heavy equipment service generally represents several months to over a year of active operation depending on shift patterns.
  • The DS11 59A engine, fitted in the H450 and H520, and the DS11 66A engine, fitted in the H320, H370, and H420, both follow the same 2000-hour change interval despite being distinct engine variants within the Scania DS11 family.
