Linde Forklift trucks, diesel (023 series)

Coolant capacity & service interval

Linde Forklift trucks, diesel (023 series) require coolant with a capacity range of 50 to 60 liters. Service intervals include a check every 10 hours and a change every 2000 hours. 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 models, both fitted with the Scania DS11 66A engine, share an identical cooling system capacity of 50 liters, while the H420, H450, and H520 each carry a larger 60-liter capacity, reflecting the greater thermal management demands of their respective configurations.
  • The 10-hour check interval across all five models is consistent with heavy-duty industrial equipment standards, where coolant level and condition are monitored far more frequently than in on-road vehicles due to continuous operational cycles and high engine loads typical of forklift applications.
  • All five models share a 2000-hour coolant change interval under normal use conditions, a figure that corresponds to roughly one to two years of intensive forklift operation depending on shift patterns.
  • The Linde Forklift trucks, diesel (023 series) H420 carries a 60-liter cooling system capacity despite sharing the same Scania DS11 66A engine family as the H320 and H370, indicating a larger or differently routed cooling circuit rather than a difference in engine displacement alone.
  • The H450 and H520 are equipped with the Scania DS11 59A variant rather than the 66A, yet both share the same 60-liter capacity and identical check and change intervals as the H420, suggesting the cooling system architecture is consistent across the higher-capacity models regardless of engine sub-variant.
  • A 50-liter cooling system fill is a substantial volume, characteristic of large industrial diesel engines where extended coolant passages, large radiator cores, and supplemental cooling circuits contribute to overall system volume well beyond typical automotive scales.
