Tadano Faun Rough terrain cranes

Coolant capacity & service interval

Tadano Faun Rough terrain cranes utilize coolant with a capacity range of 26 to 36 liters. Service intervals consist of 2000 hours or 24 months and 2400 hours 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 Tadano Faun GR-700EX with the Mitsubishi 6M60-TLU3B engine carries the largest cooling system capacity in the lineup at 36 liters, reflecting the greater thermal load of a 700-class rough terrain crane compared to smaller models.
  • The GR-550EX with the Mitsubishi 6M60-TLU3B (EU IIIA) engine has a cooling system capacity of 30.3 liters, placing it between the GR-150XL at 29.7 liters and the GR-700EX at 36 liters.
  • The Tadano Faun GR-150XL equipped with the Mitsubishi 4M50-TLA3B engine holds 29.7 liters of coolant, a figure consistent with a mid-displacement four-cylinder engine in a heavy-duty application where extended coolant passages and a large reservoir are standard.
  • Both the GR-300EX EU IIIA (2007-2011) and EU IIIB (2012-2015) variants, each powered by the Cummins QSB6.7, share an identical cooling system capacity of 26 liters, indicating no change to the cooling circuit between the two emissions-tier configurations.
  • The GR-700EX carries a change interval of 2,400 hours or 24 months under normal use conditions, which is 400 hours longer than the 2,000-hour interval specified for all other models in the group. The 24-month calendar limit remains the same across all configurations.
  • The 2,000-hour or 24-month coolant change interval applied to the GR-150XL, GR-300EX, and GR-550EX under normal use conditions reflects a dual-trigger service schedule, meaning whichever limit is reached first governs the service event.
  • The EU IIIA and EU IIIB designations on the GR-300EX refer to European exhaust emissions standards for non-road mobile machinery. The transition from EU IIIA to EU IIIB between the 2011 and 2012 model years did not alter the 26-liter coolant capacity or the 2,000-hour/24-month service interval.
