Additional Notes

  • Across the Shibaura SP series from 1988-1991, cooling system capacities vary considerably by model, ranging from 3.2 liters in the smaller configurations up to 10 liters in the largest, reflecting the differences in engine displacement and block size across the lineup.
  • The SP 1400, 1440, SP 1800, 1840, and SP 2100, 2140 all share an identical cooling system capacity of 3.2 liters, indicating a common engine block or cooling jacket design across these three model pairs despite their differing model designations.
  • The SP 2500 and 2540 step up to a 5.6-liter cooling system capacity, representing a significant increase over the 3.2-liter figure shared by the smaller models and suggesting a meaningfully larger engine with greater thermal output requiring more coolant volume.
  • The SP 4500 and 4540 carry an 8-liter cooling system capacity, placing them in a distinct tier between the 5.6-liter and 10-liter configurations within the SP range for 1988-1991.
  • The SP 5500 and 5540 hold the largest cooling system capacity in the SP series at 10 liters. A larger coolant volume generally corresponds to a bigger engine with higher heat rejection demands, requiring proportionally more fluid to maintain stable operating temperatures.
  • All six model groupings across the 1988-1991 SP series share a uniform coolant check interval of 10 hours under normal use conditions. A 10-hour check interval is characteristic of agricultural or industrial equipment, where operating cycles are measured in engine hours rather than distance traveled.
  • The pairing of base and four-wheel-drive variants within each model group, such as the SP 1400 and SP 1440, shares identical cooling system specifications, indicating that the drivetrain configuration does not affect coolant capacity or check interval for these models.
