Valtra (Valmet) N3 HiTech/HiTech 5

Coolant capacity & service interval

Valtra (Valmet) N3 HiTech/HiTech 5 coolant capacity ranges from 18 to 19 liters. Service intervals include checks every 10 hours and changes every 2000 hours or 24 months. The data covers 7 configurations.

Additional Notes

  • Across the Valtra (Valmet) N3 HiTech/HiTech 5 range for 2012-2016, cooling system capacities fall into two distinct values: 19 liters for the N103 H, N113 H, N123 H, and N143 H, and 18 liters for the N93 H, N93 H5, and N103 H5.
  • The 1-liter difference between the HiTech and HiTech 5 variants of the N103 — 19 liters versus 18 liters — mirrors the same capacity gap seen between the N93 H and N93 H5, suggesting the HiTech 5 transmission configuration influences total cooling system volume in those models.
  • A cooling system capacity of 18-19 liters is consistent with agricultural tractor cooling circuits, which typically encompass the engine block, cylinder head, radiator, and associated hoses rather than the engine block alone.
  • The change interval of 2000 hours or 24 months, whichever comes first, applies under normal use conditions across all seven configurations. The dual-trigger format means calendar time can mandate a change even when the hour threshold has not been reached.
  • The 10-hour check interval for coolant level is notably short relative to the 2000-hour change interval. In agricultural equipment, frequent level checks at 10-hour increments are standard practice given the high thermal loads and extended continuous operation common in field work.
  • All seven configurations share identical service intervals — 10-hour checks and 2000-hour/24-month changes — regardless of engine displacement differences across the N93, N103, N113, N123, and N143 variants.
