Steyr CVT (Kommunal)

Coolant capacity & service interval

Steyr CVT (Kommunal) coolant capacity is 25 liters. Service intervals include checks every 10 hours and changes every 1000 hours or 24 months. Data covers 4 configurations.

Additional Notes

  • The Steyr CVT (Kommunal) cooling system capacity is 25 liters across the CVT 120, CVT 130, CVT 150, and CVT 170 variants, along with their respective KCVT counterparts. A 25-liter figure is consistent with larger agricultural and municipal tractor engines, where extended coolant volumes help manage heat across high-load operating cycles.
  • The check interval for the cooling system is set at every 10 hours of operation across all four variants. In tractor applications, a 10-hour check interval reflects the expectation of frequent inspections during early or intensive use periods, allowing for early detection of leaks or level drops before a full service is due.
  • The coolant change interval is specified at 1000 hours or 24 months, whichever comes first, and applies uniformly to the CVT 120, CVT 130, CVT 150, and CVT 170 configurations under normal use conditions. The dual-trigger format means calendar time can mandate a change even when the hourly threshold has not been reached, which is relevant for machines with lower annual operating hours.
  • All four model variants share an identical capacity, check interval, and change interval. The uniformity across the CVT 120 through CVT 170 range suggests a common cooling system architecture despite the differing power outputs implied by the model designations.
  • The 1000-hour service life for coolant in the KCVT variants aligns with the extended drain intervals typical of modern pre-mixed or OAT-based coolant formulations used in heavy-duty machinery, where inhibitor depletion rather than contamination is the primary driver of change intervals.
