Additional Notes

  • The Valtra (Valmet) N5 HiTech cooling system capacity is 18 liters across all four variants: the N135, N155, N155E, and N175 HiTech. A uniform capacity across all variants in a lineup indicates a shared engine cooling architecture rather than variant-specific cooling volumes.
  • The 18-liter cooling system capacity represents a service fill figure, meaning the volume of coolant required to fill the system during a standard drain and refill procedure under normal operating conditions.
  • A coolant level check interval of 10 hours applies to all four variants. In heavy-duty agricultural equipment, a 10-hour check interval aligns with daily or near-daily inspection routines, reflecting the operational demands placed on cooling systems in field use.
  • The coolant change interval is specified at 2400 hours or 24 months, whichever comes first, for all four variants under normal use conditions. The dual-trigger format means calendar time can mandate a change even when the hourly threshold has not been reached, which is relevant for equipment used at lower annual hours.
  • The N135, N155, N155E, and N175 HiTech all share identical check and change intervals, indicating no differentiation in cooling system service schedules between the standard and E-suffix variants despite any powertrain distinctions those designations may represent.
  • All four variants carry a 2021 start year, and the cooling system specifications apply uniformly from that point forward without variation tied to model year within the listed data.
