Additional Notes

  • The Iseki SF200TH and SF230FH share an identical cooling system capacity of 4.5 liters, placing both models at the lower end of the SF series coolant range.
  • The SF310 and SF370 each carry a capacity range of 5.2–6.3 liters rather than a fixed value, reflecting variation across configurations within those models.
  • The SF438 and SF450 represent the largest cooling systems in the SF series, with capacities of 6.5–7.5 liters and 7–8 liters respectively, consistent with higher-output engines requiring greater thermal management volume.
  • Models introduced from 2013, the SF438 and SF450, carry a 24-month coolant change interval under normal use conditions, double the 12-month interval specified for earlier SF series models.
  • All ten models share a 10-hour coolant level check interval under normal use conditions, regardless of differences in capacity or change interval.
  • The SFH220T and SFH240F, both introduced from 2008, share a cooling system capacity of 4.7 liters and a 12-month change interval under normal use conditions, placing them close to but slightly above the SF200TH and SF230FH in total coolant volume.
  • The SF300 and SF330 each hold a fixed 5.3-liter capacity, distinguishing them from the SF310 and SF370 which carry variable capacity ranges despite occupying a similar position in the model lineup.
