N163 D (Direct) (2012-2016)
  • Use: Normal
  • Capacity 19 liter
  • Check 10 hours
  • Change 2000 hours/ 24 months

Additional Notes

  • Both the N143 D and N163 D carry a cooling system capacity of 19 liters, which represents the total system fill volume including the engine block, radiator, and associated hoses.
  • The Valtra N3 Direct N143 D and N163 D share identical coolant service intervals, with a change interval set at 2000 hours or 24 months, whichever comes first under normal use conditions.
  • A coolant level check interval of 10 hours applies to both the N143 D and N163 D under normal use, reflecting the relatively short inspection cycle typical of agricultural machinery operating in demanding field conditions.
  • The 24-month time-based change interval runs alongside the 2000-hour threshold, meaning a calendar limit governs coolant replacement even when hour accumulation is low across both engine variants.
  • The N143 D and N163 D differ in engine output designation but share the same 19-liter cooling system capacity, indicating a common cooling architecture across the two power variants within the 2012-2016 production span.
