Valpadana 4500 Series

Coolant capacity & service interval

Valpadana 4500 Series uses coolant with a capacity of 4,8 liters. Service intervals occur every 1000 hours or 12 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 Valpadana 4500 Series carries a uniform cooling system capacity of 4.8 liters across all five configurations covered by the 2011-2016 specifications, spanning both the 4525, 4535, and 4545 model variants.
  • The 4.8-liter figure represents the total cooling system fill volume, which typically accounts for the radiator, engine block passages, and connecting hoses rather than the engine block alone.
  • All five configurations share an identical coolant change interval of 1,000 hours or 12 months, whichever comes first under normal use conditions.
  • The dual-trigger interval structure, combining an operating-hour threshold with a calendar-based limit, reflects the fact that coolant degrades both through use and through time-dependent chemical breakdown, regardless of machine activity.
  • The 4525 ISM and 4535 ISM share the same Yanmar 3TNV82A-KVA engine and identical cooling system specifications, with no capacity or interval difference between the two model designations.
  • The 4535 VRM variant also uses the Yanmar 3TNV82A-KVA engine and carries the same 4.8-liter capacity and 1,000-hour/12-month interval as the 4535 ISM, indicating the ISM and VRM body configurations do not alter the cooling system volume.
  • The 4545 ISM and 4545 VRM use the Yanmar 3TNV88 engine rather than the 3TNV82A-KVA found in the lower-numbered variants, yet the cooling system capacity remains at 4.8 liters with no change to the service interval.
