Additional Notes

  • Both the XQ 125 and XQ 150 Maxster share an identical cooling system capacity of 1.25 liters, which represents the total volume of coolant the system holds during a standard service fill.
  • A check interval of every 6,000 km applies to both engine variants under normal use conditions, meaning the coolant level and condition are inspected at that mileage point rather than replaced.
  • The change interval is defined by time rather than mileage alone, with a 36-month replacement schedule specified for both the 125 and 150 engine configurations under normal use conditions.
  • The Yamaha XQ Maxster's time-based drain interval of 36 months reflects how coolant degrades chemically over time regardless of distance traveled, making calendar age a relevant factor alongside mileage in service planning.
  • No variation in cooling system capacity or service intervals exists between the 125 cc and 150 cc engine variants, with both sharing the 1.25-liter fill, 6,000 km check, and 36-month change specifications across the 2001-2003 model years.
