Ahlmann Front loaders, AF

Coolant capacity & service interval

Ahlmann Front loaders, AF use coolant with a capacity of 14 liters. Service intervals include checks at 50 hours and changes at 1500 hours. The data covers 4 configurations.

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

Additional Notes

  • Across all four configurations of the Ahlmann Front loaders, AF series covered here, the cooling system capacity is 14 liters, a figure that reflects a full system fill including the engine block, radiator, and associated hoses rather than a partial top-up volume.
  • The 50-hour check interval applies uniformly under normal use conditions across the AF 1050 and AF 1200 models, regardless of which Cummins engine variant is fitted.
  • The coolant change interval is set at 1500 hours under normal use conditions for every configuration listed, spanning the AF 1050 with the naturally aspirated B3.3, the AF 1050 with the turbocharged B3.3T, the AF 1200 with the B3.3T, and the AF 1200 with the aftercooled B3.3TAA.
  • The AF 1050 is available with either the Cummins B3.3 or the turbocharged B3.3T, yet both share an identical 14-liter cooling system capacity, indicating the turbocharger addition on the B3.3T did not alter the cooling circuit volume in the 2010-2015 period.
  • The AF 1200 pairs with either the B3.3T or the more advanced B3.3TAA, where the TAA designation denotes a turbocharged and aftercooled configuration. Despite the added thermal management demands of aftercooling, the cooling system capacity remains at 14 liters, consistent with the other variants.
