Case - IH CS

Coolant capacity & service interval

Case - IH CS coolant capacity ranges from 12 to 25 liters. Service intervals include checks at 10 hours and changes at 1000 hours/24 months or 2400 hours. The data covers 7 configurations.

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

Additional Notes

  • The Case-IH CS 78, CS 86, and CS 94 each hold 12 liters of coolant, the smallest capacity across the CS series, reflecting the smaller engine displacement in the lower-tier models of the range.
  • The CS 120, CS 130, and CS 150 share an identical 25-liter cooling system capacity, indicating a common engine cooling architecture across those three variants despite their differing power outputs.
  • The CS 110 carries a 21-liter cooling system capacity, placing it between the 12-liter lower models and the 25-liter upper models, consistent with a mid-range engine configuration.
  • All seven CS variants share the same 10-hour coolant check interval under normal use conditions, a frequency typical of heavy-duty agricultural equipment where thermal stress and hose integrity require regular monitoring.
  • The CS 78, CS 86, and CS 94 specify a coolant change interval of 1000 hours or 24 months, whichever comes first. The dual-trigger format means calendar time can mandate a change even when operational hours remain below the threshold.
  • The CS 110, CS 120, CS 130, and CS 150 specify a coolant change interval of 2400 hours, more than double the 1000-hour interval of the smaller models. A 2400-hour interval is associated with extended-life coolant formulations designed for higher-output engines with greater thermal demands.
  • The CS 150 has the earliest start year in the upper-capacity group, with specifications covering 1997-2004, while the CS 110 enters the range later, from 1999-2004, giving it the shortest model year span among all seven variants.
