Shibaura ST

Coolant capacity & service interval

Shibaura ST coolant capacity is 3,5 liters. Service intervals include 10 hours for checks and 12 months for changes. The data covers 3 configurations.

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

Additional Notes

  • The Shibaura ST318, ST321, and ST324 each share an identical cooling system capacity of 3.5 liters, which represents the total service fill volume for the cooling circuit.
  • A 3.5-liter cooling system capacity is relatively modest, consistent with the compact engine displacement typical of small utility tractors in the ST series.
  • The coolant check interval is set at every 10 hours of operation under normal use conditions, reflecting a frequent early-inspection schedule suited to equipment operating in variable field environments.
  • The coolant change interval is defined by a 12-month calendar period rather than an hourly threshold, meaning time elapsed governs the drain-and-refill cycle regardless of how many hours the machine has accumulated.
  • All three configurations, the ST318, ST321, and ST324, carry the same check and change intervals of 10 hours and 12 months respectively, indicating no differentiation in cooling service schedules across the model variants within the 1998-2005 production span.
  • The uniform 3.5-liter capacity across the ST318, ST321, and ST324 suggests the three models share a common cooling system architecture despite their differing model designations.
