Yanmar Wheeled excavators

Coolant capacity & service interval

Yanmar wheeled excavators require coolant with a capacity of 15 liters. The service interval for coolant 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 Yanmar Wheeled Excavators B95W AL, B95W S, and B95W variants — all Stage IV/Tier 4f, serial number TW09540100 onward from 2018 — share an identical cooling system capacity of 15 liters.
  • A 15-liter cooling system capacity is a relatively substantial fill volume for a wheeled excavator, reflecting the thermal management demands of a Stage IV/Tier 4f emissions-compliant engine, which typically incorporates aftertreatment components that generate additional heat load.
  • The coolant change interval across all three configurations is 24 months under normal use conditions, meaning the interval applies to standard operating environments rather than extended heavy-duty or extreme-temperature service.
  • The uniformity of both the 15-liter capacity and the 24-month change interval across the AL, S, and base B95W trim levels indicates no variation in cooling system specifications among these configurations for the 2018 serial number range.
