Fenwick Container handlers (318 series)

Coolant capacity & service interval

Fenwick Container handlers (318 series) require 20 liter of coolant. Service intervals include a check every 10 hours and a change every 2000 hours. The data covers 4 configurations.

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

Additional Notes

  • The Fenwick Container handlers (318 series) cooling system holds 20 liters across the C90/5, C90/6, C90/7, and C90/8 configurations, all of which are equipped with the Cummins QSB6.7 engine. A 20-liter capacity is consistent with a mid-displacement inline six-cylinder industrial engine of QSB6.7 proportions, where the figure reflects the total cooling system volume including the engine block, cylinder head passages, hoses, and radiator.
  • The coolant check interval is set at 10 hours across all four configurations under normal use conditions. In heavy equipment applications, a 10-hour check interval aligns with a daily or shift-based inspection routine, reflecting the operational demands placed on cooling systems in container handling environments.
  • The coolant change interval is 2000 hours for all four configurations under normal use conditions. At a typical industrial workload of around 2000 operating hours per year, a 2000-hour change interval corresponds roughly to an annual service cycle.
  • The capacity figure of 20 liters is identical across the C90/5, C90/6, C90/7, and C90/8 variants. Since all four share the Cummins QSB6.7 engine, the uniform cooling system volume reflects a common engine architecture rather than variation introduced by differing powertrains.
  • The check and change intervals are also uniform across all four configurations at 10 hours and 2000 hours respectively, indicating that the rated lift capacity differences between the C90/5, C90/6, C90/7, and C90/8 variants do not alter the coolant service schedule under normal use conditions.
