Volvo VNM series (USA / CAN)

Coolant capacity & service interval

Volvo VNM series (USA / CAN) uses coolant with a capacity of 43.5 liters. Service intervals require a check every 24000 km. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Volvo VNM series (USA / CAN) cooling system holds 43.5 liters across the 430, 630, and Daycab configurations for the 2002-2007 model years.
  • A 43.5-liter cooling system capacity is consistent with heavy-duty commercial truck engines, where large coolant volumes are necessary to manage heat rejection from high-displacement powerplants under sustained load conditions.
  • The 430, 630, and Daycab variants share an identical 43.5-liter capacity, indicating a common cooling system architecture across all three configurations within the 2002-2007 production span.
  • The specified check interval for the cooling system is 24,000 km under normal use conditions, applying uniformly to all three VNM configurations in the 2002-2007 range.
  • A 24,000 km check interval for coolant is a routine inspection point rather than a full fluid replacement interval, typically used to verify concentration levels, pH, and the condition of inhibitor packages in heavy-duty coolant formulations.
