Additional Notes

  • The Arctic Cat 425/450 series cooling system capacity splits into two distinct values across the lineup: 2.9 liters and 1.8 liters. A larger cooling system volume generally reflects a more extensive coolant circuit, while a smaller figure indicates a more compact or revised system design.
  • The 425 4x4 (2011-2012) and the 450 (2010-2012) share an identical 2.9-liter cooling system capacity, suggesting a common engine cooling architecture between the two configurations during that period.
  • The 450 (2015-2016) retains the 2.9-liter capacity seen in the earlier 2010-2012 450, indicating no reduction in cooling system volume despite the gap in model years between the two entries.
  • The XC 450 shows a capacity change between model year groups. The 2013-2014 XC 450 carries a 2.9-liter cooling system, while the 2015-2017 XC 450 drops to 1.8 liters, a reduction of 1.1 liters that points to a revised cooling circuit in the later configuration.
  • The XC 450i 4x4 (2011-2013) uses a 1.8-liter cooling system capacity, which aligns with the later 2015-2017 XC 450 rather than the 2.9-liter figure seen in the standard 450 of the same era.
  • All six configurations across the 425/450 series carry a uniform 24-month coolant change interval under normal use conditions. A time-based interval of this type is standard practice for ethylene glycol coolants, which degrade in corrosion inhibitor effectiveness over time regardless of mileage or hours of operation.
