Additional Notes

  • The Optum CVX cooling system maintains a uniform capacity of 21 liters across all engine variants and emissions standards covered in the 2016-2020 range.
  • Coolant level checks occur at 10-hour intervals for normal operating conditions across all Optum 270 CVX and Optum 300 CVX configurations.
  • Coolant change intervals follow a dual-criterion schedule of 48 months or 3600 hours, whichever occurs first, for both Stage V and Tier 4b/Stage IV emissions standards.
  • The Optum 300 CVX Tier 4b/Stage IV model begins in 2016, while the Stage V variant introduction occurs in 2020, yet both maintain identical coolant capacity and service intervals.
  • The Optum 270 CVX Tier 4b/Stage IV variant enters the lineup in 2018, sharing the same 21-liter capacity and maintenance schedule as earlier and later model iterations.
