Iseki TLE

Coolant capacity & service interval

Iseki TLE coolant capacity ranges from 5 to 6,7 liters. Service intervals include checking at 10 hours and changing at 600 hours or 24 months. The data covers 2 configurations.

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

TypeSpecifications

TLE4490(FS), Iseki E4CG-WB34 (2016- )
  • Use: Normal
  • Capacity 6,7 liter
  • Check 10 hours
  • Change 600 hours/ 24 months

Additional Notes

  • The Iseki TLE3400(FH) with the E3CD-WTB11 engine holds 5 liters of coolant in the cooling system, while the TLE4490(FS) with the E4CG-WB34 engine holds 6.7 liters, reflecting the larger displacement of the four-cylinder configuration compared to the three-cylinder unit.
  • Both configurations share a coolant check interval of every 10 hours of operation, which is a short-cycle inspection interval typical of compact utility tractors working under continuous load conditions.
  • The coolant change interval for both the E3CD-WTB11 and E4CG-WB34 engines is set at 600 hours or 24 months under normal use, whichever comes first, meaning time elapsed can trigger a change even when the hour threshold has not been reached.
  • The 1.7-liter difference in cooling system capacity between the two TLE variants indicates a meaningfully larger coolant circuit in the TLE4490(FS), which corresponds to the greater thermal load generated by a higher-output engine.
