Additional Notes
- The Wirtgen WM1000 with the Cummins QSB6.7-C engine carries a cooling system capacity of 8.9 liters across both the Tier 3/Stage IIIa and Tier 4i/Stage IIIb emissions configurations.
- The 8.9-liter figure represents a service fill capacity, meaning the volume of coolant required to properly fill the cooling system during a standard maintenance interval rather than a full overhaul procedure.
- A 24-month change interval applies to both emissions variants of the WM1000 under normal use conditions, meaning the coolant replacement schedule is not differentiated by the engine's emissions tier.
