Irisbus Axer

Coolant capacity & service interval

Irisbus Axer coolant capacity is 84 liters. Service intervals include checks every 6 months and changes every 24 months. Data covers 2 configurations.

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

  • Use: Normal
  • Capacity 84 liter
  • Check 6 months
  • Change 24 months
Axer 12,8 m Euro 3 (2004-2006)
  • Use: Normal
  • Capacity 84 liter
  • Check 6 months
  • Change 24 months

Additional Notes

  • Both the Axer 12 m and the Axer 12.8 m Euro 3 variants share an identical cooling system capacity of 84 liters, which is a figure consistent with large coach-class vehicles where extended coolant volumes are needed to manage heat across long engine and cabin circuits.
  • The 84-liter capacity listed for each variant reflects a full cooling system fill, meaning the figure accounts for the entire system volume rather than a partial service top-up quantity.
  • Under normal use conditions, the coolant change interval for both the Irisbus Axer 12 m and 12.8 m Euro 3 is set at 24 months, placing the drain-and-refill cycle on a two-year schedule.
  • A separate check interval of 6 months is specified alongside the 24-month change interval, meaning the cooling system is inspected four times before a full fluid replacement is due under normal use conditions.
  • The 2004-2006 model years covered by both rows carry uniform capacity and interval figures, indicating no revision to coolant specifications occurred across the production span represented in the data.
