Additional Notes

  • The LSTractor J Series cooling system capacity is 3.8 liters across all five configurations covered by these specifications, including the J2020H, J2023H, J2030H, J23HST, and J27HST.
  • A 3.8-liter cooling system capacity represents a full system fill volume, accounting for the radiator, engine block passages, and connecting hoses rather than a partial top-off quantity.
  • The coolant check interval is set at 10 hours of operation under normal use conditions, which reflects how frequently the coolant level should be inspected rather than replaced.
  • The coolant change interval across all listed configurations is 600 hours under normal use conditions, a figure that applies uniformly regardless of whether the transmission type is gear-driven or hydrostatic.
  • The J23HST and J27HST carry hydrostatic transmission designations and share the same 3.8-liter cooling system capacity and 600-hour change interval as the gear-drive J2020H, J2030H, and J2023H models.
  • The J2023H introduced in 2014 shares identical cooling system specifications with the J2020H and J2030H, both of which entered the lineup in 2009, indicating no change in cooling system design between those introduction years.
