Vermeer Tracked trenchers

Coolant capacity & service interval

Vermeer tracked trenchers require coolant with a capacity of 13.9 liters. Service intervals occur every 2000 hours or 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 T755 Commander 3, T855 Commander 3, and T858 Commander 3 each carry a cooling system capacity of 13.9 liters, measured at the engine only.
  • An engine-only capacity figure means the 13.9-liter value reflects the engine block and associated passages, not the full system volume including any external reservoir or additional circuit.
  • The coolant change interval across all three Commander 3 models is set at 2000 hours or 24 months, whichever comes first, under normal use conditions.
  • A 2000-hour service interval for coolant is relatively extended, which is consistent with heavy-duty diesel applications where long-life coolant formulations are typically specified.
  • The identical 13.9-liter capacity and 2000-hour/24-month change interval across the T755, T855, and T858 Commander 3 models indicates a shared engine cooling architecture among the three tracked trencher configurations.
