Aro 24

Coolant capacity & service interval

Aro 24 uses coolant with a capacity range of 13,25 to 15,6 liters. Service intervals require changes every 20000 km or 24 months. The data covers 5 configurations.

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

Additional Notes

  • The Aro 24 2.5 D and 24 2.5 TD share an identical cooling system capacity of 15.6 liters, which is the largest figure across all five engine variants listed.
  • The 24 2.5 petrol and 24 2.7 D both carry a cooling system capacity of 13.25 liters, placing them at the lower end of the capacity range among the configurations covered.
  • The 24 3.1 D sits between the two capacity groups with a 15-liter cooling system fill, neither matching the 13.25-liter nor the 15.6-liter figures seen in the other variants.
  • A 15.6-liter cooling system capacity, as seen in the 2.5 D and 2.5 TD engines, typically reflects a larger or more thermally demanding engine block requiring greater coolant volume to maintain operating temperatures.
  • All five engine variants share the same service interval of 20,000 km or 24 months under normal use conditions, whichever comes first.
  • The 24 2.5 TD, introduced from 1993, carries the same 15.6-liter capacity and 20,000 km interval as the 2.5 D, despite the addition of turbocharging.
  • The 24 2.5 D has the longest production span among the listed variants, running from 1980-2006, and maintains a consistent 15.6-liter capacity and 20,000 km change interval throughout.
