Iseki SX

Coolant capacity & service interval

Iseki SX coolant capacity ranges from 9 to 20 liters. Service intervals require a change every 400 hours or 12 months. The data covers 2 configurations.

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

TypeSpecifications
SX 75 (1988-1992)
  • Use: Normal
  • Capacity 9 liter
  • Change 400 hours/ 12 months
SX 95 (1988-1992)
  • Use: Normal
  • Capacity 20 liter
  • Change 400 hours/ 12 months

Additional Notes

  • The Iseki SX 75 cooling system holds 9 liters of coolant, a capacity typical of compact utility tractors with smaller engine displacement.
  • The SX 95 cooling system carries a 20-liter capacity, more than double that of the SX 75, reflecting the larger engine and greater thermal load management requirements of the higher-output model.
  • Both the SX 75 and SX 95 share an identical coolant change interval of 400 hours or 12 months under normal use conditions, whichever comes first.
  • The dual-trigger interval structure, combining an operating-hours threshold with a calendar-based limit, means a machine with low annual usage would still require a coolant change at the 12-month mark regardless of hours accumulated.
  • Both configurations are rated under normal use conditions, meaning the 400-hour and 12-month intervals apply to standard operating environments rather than severe or demanding duty cycles.
