Terex PPM Mobile truck cranes

Coolant capacity & service interval

Terex PPM mobile truck cranes require coolant with a capacity range of 34 to 59 liters. The data covers 2 configurations.

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

TypeSpecifications
AC55
  • Use: Normal
  • Capacity 34 liter
ATT900
  • Use: Normal
  • Capacity 59 liter

Additional Notes

  • The AC55 cooling system carries a capacity of 34 liters, a figure consistent with the total system volume used during a full coolant service fill on a mid-range crane powertrain.
  • The ATT900 cooling system holds 59 liters, reflecting the larger engine displacement and extended cooling circuit typical of a heavier-duty all-terrain crane configuration.
  • Between the two configurations, the ATT900 cooling system capacity exceeds the AC55 by 25 liters, indicating a substantially larger thermal management circuit in the higher-tonnage model.
  • Both the AC55 and ATT900 cooling system specifications are listed under normal use conditions, meaning the stated capacities apply to standard operating environments rather than severe-duty cycles.
