Additional Notes

  • The Yamaha Phazer cooling system capacity is 3.6 liters across all listed variants, from the base PZ50 to the Mountain Lite, GT, FX, MTX, RTX, and XTX trims. A consistent capacity across a model family typically reflects a shared engine and cooling circuit architecture.
  • The 3.6-liter figure represents the total cooling system fill volume, meaning the amount of coolant required to fill the entire circuit, including the radiator, hoses, and engine passages, rather than a partial drain-and-refill quantity.
  • The Phazer MTX (2009-2017), Phazer RTX (2009-2017), and Phazer XTX (2014-2018) each carry an explicit coolant change interval of 2,500 miles, 200 hours, or 12 months, whichever comes first under normal use conditions. Earlier variants of the same trims, such as the PZ50MT and PZ50VT covering 2008-2009, do not carry a listed change interval in the specifications.
  • The triple-format interval of miles, hours, and months on the MTX, RTX, and XTX reflects the varied ways snowmobiles accumulate use. Odometer distance, engine runtime hours, and calendar time each serve as independent triggers, so whichever threshold is reached first determines when a coolant change is due.
  • The Phazer GT, PZ50GT appears across three separate row entries covering 2007-2008, 2008-2009, and 2009-2014, all specifying the same 3.6-liter capacity. The overlapping model year boundaries between the first two entries suggest a mid-season or transitional production designation rather than a specification change.
  • The Phazer XTX (2014-2018) shares the same 3.6-liter capacity and 2,500-mile/200-hour/12-month interval as the MTX and RTX variants, indicating a common cooling system specification despite the XTX representing a later and distinct trim within the Phazer lineup.
