Weidemann Telescopic loaders

Coolant capacity & service interval

Weidemann Telescopic loaders require coolant with a capacity range of 8,5 to 10 liters. The service interval for coolant changes is 24 months. The data covers 3 configurations.

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

Additional Notes

  • The Weidemann Telescopic loaders T4512 with the 23 kW Yanmar 3TNV82A engine carries a cooling system capacity of 8.5 liters, which reflects the total volume of coolant the system holds during a service fill.
  • The T4512 fitted with the 30 kW Yanmar 3TNV84T engine shares the same 8.5-liter cooling system capacity as the lower-output variant, despite the difference in engine power output.
  • Both T4512 configurations specify a 24-month change interval under normal use conditions, meaning the coolant replacement schedule is tied to time rather than operating hours.
  • The T5522 with the Perkins 404F-22T engine carries a larger cooling system capacity of 10 liters, reflecting the greater displacement and thermal management demands of the Perkins unit compared to the Yanmar-powered T4512 models.
  • The T5522 also follows a 24-month change interval under normal use conditions, aligning with the same time-based service schedule applied across all three configurations in the specifications.
  • All three configurations introduced from 2009 and 2013 respectively share the normal use condition designation, meaning none of the listed entries carry a separate severe-duty interval specification.
