Menzi Muck Tracked excavators, Eurocomach

Coolant capacity & service interval

Menzi Muck Tracked excavators, Eurocomach use coolant with a capacity of 25 liters. Service intervals include checking every 10 hours and changing every 1000 hours or 12 months. The data covers 4 configurations.

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

Additional Notes

  • All four Menzi Muck Tracked Excavators covered here — the 100na, 100sa, 100va, and 100za — share the Yanmar 4TNV98-ZSPR engine from serial number 00051 onward, and each carries an identical cooling system capacity of 25 liters. A 25-liter figure is consistent with a full cooling system fill, accounting for the engine block, cylinder head passages, radiator, and hoses rather than a partial or top-up quantity.
  • The 10-hour check interval for coolant level is notably short and reflects the demands of heavy equipment operation, where heat cycling, minor seepage, and hose connections can cause gradual fluid loss that warrants frequent visual inspection.
  • The coolant change interval is set at 1,000 hours or 12 months under normal use conditions, whichever comes first. The dual trigger means that machines with lower annual operating hours still require a coolant change on a calendar basis, since coolant additives degrade over time regardless of engine runtime.
  • The 1,000-hour service interval is a common benchmark in construction and agricultural equipment for coolant replacement, as inhibitor packages that protect against corrosion and cavitation erosion typically lose effectiveness around that threshold under normal operating conditions.
  • The uniform 25-liter capacity across the 100na, 100sa, 100va, and 100za variants indicates that despite differences in machine configuration implied by the distinct model suffixes, the cooling circuit architecture tied to the Yanmar 4TNV98-ZSPR engine remains consistent across all four.
