Kymco MXU

Coolant capacity & service interval

Kymco MXU coolant capacity ranges between min and max values. Service intervals include checks at 150 km or 1 month and 1000 km or 6 months, with a change interval of 24 months. The data covers 7 configurations.

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

Additional Notes

  • Coolant level across all Kymco MXU variants is specified as a range rather than a fixed volume, with the acceptable fill sitting between a marked minimum and maximum on the reservoir or sight glass. A between-min-and-max specification is typical for service-level checks where topping up is the expected action rather than a full drain and refill.
  • The Kymco MXU 250 and MXU 500 (2007-2011) share an initial service coolant check interval of 150 km or 1 month, whichever comes first. An early break-in inspection at such a short interval reflects the need to confirm system integrity and catch any seepage before normal service intervals take over.
  • Following the initial service period, the MXU 250 transitions to a normal-use check interval of every 1,000 km or 6 months. The MXU 500 (2007-2011) carries the same 1,000 km or 6-month check schedule under normal use conditions.
  • The MXU 300, MXU 400 (2008- ), and MXU 700i (2012- ) carry no periodic check interval in their normal-use specifications, only the 24-month coolant change interval. The absence of a scheduled level check in those rows contrasts with the explicit check intervals listed for the MXU 250 and MXU 500 (2007-2011).
  • A 24-month coolant change interval applies uniformly across the MXU 250, MXU 300, MXU 400, MXU 500 (2007-2011), and MXU 700i under normal use. A time-based rather than distance-based change interval for coolant is standard practice, since coolant degrades chemically over time regardless of mileage accumulated.
  • The MXU 500 spans model years 2007-2011, while the MXU 700i begins from 2012. The two displacements do not overlap in the covered year range, and the larger 700i carries a fuel-injected designation reflected in its model name suffix "i," which distinguishes it from the carbureted configurations of the smaller-displacement variants.
