Ammann Rubber tyred rollers, AP

Coolant capacity & service interval

Ammann Rubber tyred rollers, AP use coolant with a capacity range of 11,5 to 20,5 liters. Service intervals include checks every 20 hours and changes every 24 months or 2000 hours. The data covers 4 configurations.

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

Additional Notes

  • The Ammann Rubber tyred rollers, AP cooling system capacity varies between configurations despite sharing the same engine displacement family. The AP 240 H with the Cummins 4BT4.5-C99 T2 and T3 engines both hold 20.5 liters, as does the AP 240 with the T2 engine, while the AP 240 with the T3 engine holds only 11.5 liters.
  • A 20.5-liter coolant capacity is a relatively large fill volume for a compact four-cylinder engine, suggesting the cooling circuit includes significant external components such as an expansion tank, oil cooler passages, or extended hose routing within the machine frame.
  • The AP 240 paired with the Cummins 4BT4.5-C99 T3 engine carries a notably smaller 11.5-liter capacity compared to the otherwise identical AP 240 H T3 configuration at 20.5 liters, a difference of 9 liters between two machines sharing the same engine designation.
  • All four configurations share a coolant check interval of 20 hours, which is a short-cycle inspection point consistent with heavy-duty compaction equipment operating in dusty or thermally demanding environments.
  • The coolant change interval across all four configurations is set at 24 months or 2000 hours, whichever comes first. The dual-trigger structure means time-based degradation is accounted for even when the machine accumulates hours slowly.
  • A 2000-hour change interval for coolant is a moderate service life, reflecting the use of a conventional or extended-life coolant formulation that requires periodic replacement to maintain corrosion inhibitor effectiveness within the engine block and radiator.
  • All specifications listed apply under normal use conditions, meaning the 20-hour check and 24-month/2000-hour change intervals are not adjusted for severe-duty operation in the data provided for the 2006-2012 model range.
