Additional Notes

  • The Yamaha GDR Aerox 155 / NVX 155 carries a radiator capacity of 0.46 liter, which represents the total volume the main cooling circuit holds during a service fill.
  • A separate reservoir capacity of 0.13 liter is specified alongside the radiator figure, reflecting the overflow or expansion tank volume that sits outside the primary circuit.
  • The combined cooling system volume across both the radiator and reservoir amounts to 0.59 liter, a relatively modest total consistent with a small-displacement liquid-cooled scooter engine.
  • The specified change interval for coolant is 36 months under normal use conditions, meaning the fluid replacement schedule is time-based rather than mileage-based.
  • Both the 2017-2020 and the 2020-onward GDR155 configurations share identical radiator and reservoir capacities, as well as the same 36-month change interval, indicating no revision to cooling system specifications between those entries.
