Montana Tractors
Coolant capacity & service interval
Montana Tractors require coolant with a capacity range of 4,9 to 6,1 liters. Service intervals require a check every 10 hours. The data covers 5 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Montana 30 CV and 40 CV share a cooling system capacity of 4.9 liters, indicating both models use the same engine cooling architecture despite their different power ratings.
- Starting with the Montana 45 CV, the cooling system capacity increases to 6.1 liters, a figure that also applies to the 50 CV and 60 CV models, reflecting a larger engine displacement requiring greater coolant volume.
- A 4.9-liter cooling system capacity, as seen on the lower-output Montana tractors, is a relatively modest fill volume consistent with smaller displacement engines in the compact tractor segment.
- The 6.1-liter capacity on the Montana 45 CV, 50 CV, and 60 CV represents a meaningful step up in thermal management requirements, as higher-output engines generate more heat and demand a larger coolant reservoir to maintain safe operating temperatures.
- Across all five Montana tractor configurations listed, the coolant check interval is set at 10 hours of operation under normal use conditions, making it one of the most frequent maintenance checks in the cooling system schedule.
- A 10-hour coolant check interval is notably short compared to many automotive applications, which is typical for agricultural equipment operating under sustained load, variable ambient temperatures, and dusty field conditions.
