Case - IH 55 / 56

Coolant capacity & service interval

Case - IH 55 / 56 models utilize coolant with a capacity range of 21 to 28,6 liters. Service intervals consist of checking every 50 hours and changing every 1200 hours or 24 months. The data covers 5 configurations.

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

Additional Notes

  • The Case-IH 1056 and 956 series share an identical base cooling system capacity of 24.4 liters, which rises to 28.6 liters when the air conditioning option is fitted, reflecting the additional heat exchanger volume introduced by that system.
  • The 4.2-liter difference between the standard and air-conditioning-equipped configurations on the 1056 and 956 models represents a meaningful fill volume increase that would affect the quantity of coolant concentrate required to maintain the correct antifreeze mixture ratio.
  • The 856 XL Turbo and XLA Turbo carry a notably smaller cooling system capacity of 21 liters, compared to the 24.4-liter figure shared by the 956, 1056, 1255 XL, and 1455 XL configurations.
  • The 1255 XL and 1455 XL both hold 24.4 liters and carry no air conditioning capacity variant in the specifications, unlike the 1056 and 956 which list a second capacity figure for that option.
  • Across all five configurations, the coolant check interval is set at 50 hours of operation under normal use conditions, indicating a relatively frequent monitoring requirement typical of high-load agricultural equipment.
  • The change interval is uniform across all listed configurations at 1200 hours or 24 months under normal use, whichever comes first, meaning calendar time can trigger a service event even when the hour threshold has not been reached.
