Yamaha XN TEO's

Coolant capacity & service interval

Yamaha XN TEO's coolant capacity ranges from 0,35 to 1,1 liters. Service intervals include checks every 6000 km or 12 months and fluid changes every 36 months. The data covers 2 configurations.

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

Additional Notes

  • The Yamaha XN TEO's cooling system holds a total main circuit capacity of 1.1 liters, which represents the full system fill volume for the primary cooling passages surrounding the engine.
  • A separate reservoir capacity of 0.35 liters is specified alongside the main circuit figure, reflecting the overflow and expansion tank volume that operates independently from the primary fill.
  • Both the XN 125 and XN 150 TEO's share identical coolant capacities across the main circuit and reservoir, with no displacement-related variation in either figure across the 2000-2003 model years.
  • The coolant check interval is set at 6,000 km or 12 months under normal use conditions, whichever comes first, indicating a time-and-distance dual threshold for inspection.
  • The coolant change interval is defined by a 36-month period under normal use conditions, meaning the replacement schedule is governed entirely by elapsed time rather than distance traveled.
  • The gap between the check interval of 12 months and the change interval of 36 months means a coolant change is due approximately every third inspection cycle under normal use conditions.
