LSTractor XU Series

Coolant capacity & service interval

LSTractor XU Series coolant capacity ranges from 7 to 9,4 liters. Service intervals include checking every 10 hours and changing every 24 months. The data covers 5 configurations.

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

Additional Notes

  • The LSTractor XU Series cooling system capacities fall into two distinct groups: the XU5055 and XU5065 each hold 7 liters, while the XU6158, XU6163, and XU6168 each hold 9.4 liters.
  • The 9.4-liter capacity of the XU6158, XU6163, and XU6168 reflects the larger engine displacement in the XU61 sub-series, which requires a greater volume of coolant to maintain operating temperatures across a bigger cooling circuit.
  • All five configurations share an identical coolant check interval of every 10 hours of operation, a frequency consistent with early-hour monitoring practices on utility tractors used in variable field conditions.
  • The 24-month coolant change interval applies uniformly across all XU Series configurations listed, meaning the replacement schedule is time-based rather than tied to accumulated operating hours.
  • A time-based change interval of 24 months is typical for modern extended-life coolant formulations, where chemical degradation occurs over calendar time regardless of how frequently the machine is operated.
  • All specifications are designated for normal use conditions, meaning the 10-hour check and 24-month change intervals are not adjusted for severe operating environments in the data provided.
  • The XU5055 and XU5065 share an identical 7-liter capacity despite being distinct model designations, indicating the two variants use the same cooling system architecture.
