Case - IH Quantum C

Coolant capacity & service interval

The Case - IH Quantum C coolant specifications cover a capacity range of 14 to 16 liters depending on the configuration. The data includes three different configurations. No service intervals are specified in the data.

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

Additional Notes

  • Across the Case - IH Quantum C65, C75, and C95 variants spanning 2008-2014, the cooling system capacity is listed at two distinct values: 14 liters and 16 liters, with the higher figure applying when a cabin heating circuit is included in the system.
  • The 2-liter difference between the two capacity figures reflects the additional coolant volume required to circulate through a cab heater core, which forms part of the extended cooling loop when a cabin is fitted.
  • All three variants, the C65, C75, and C95, share identical cooling system capacities despite representing different power outputs within the Quantum C range, indicating a common cooling circuit architecture across the lineup for the 2008-2014 period.
  • The specifications apply under normal use conditions, meaning the 14-liter and 16-liter figures are not adjusted for severe-duty or other alternative operating classifications within the data provided.
