McCormick CL

Coolant capacity & service interval

McCormick CL coolant capacity is 18,5 liters. Service intervals occur every 1000 hours or 12 months. The data covers 4 configurations.

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

Additional Notes

  • The McCormick CL series cooling system capacity is 18.5 liters across all four configurations — the C65L, C70L, C75L, and C80L — indicating a shared cooling system architecture despite differences in engine variants.
  • The C65L and C75L SpeedFour both use the Perkins 1103D-33T engine, while the C70L pairs with the turbocharged and aftercooled 1103D-33TA variant, and the C80L steps up to the larger displacement Perkins 1104D-44.
  • The 1104D-44 fitted to the C80L is a four-cylinder, 4.4-liter displacement engine, compared to the 3.3-liter displacement of the 1103D-series engines in the C65L, C70L, and C75L, yet all share the same 18.5-liter cooling system capacity.
  • The coolant change interval for all four configurations is specified at 1,000 hours or 12 months under normal use conditions, meaning whichever threshold is reached first would govern the service timing in practice.
  • A cooling system capacity of 18.5 liters is a relatively substantial figure for compact utility tractors, reflecting the volume of the entire system including the radiator, engine block passages, and associated hoses rather than a partial or top-up quantity.
