Iveco Daily 38

Coolant capacity & service interval

Iveco Daily 38 uses coolant with a capacity range of 9-11 liters. Service intervals require a check every 12 months. The data covers 6 configurations.

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

Additional Notes

  • The Iveco Daily 38 coolant system capacity splits into two distinct values across the 2024 lineup. The S 12, S 14, S 16, and S 16 3.0 variants all share a fixed 9-liter capacity, while the S 18 and S 21 variants carry a wider range of 9 to 11 liters.
  • A fixed 9-liter capacity, as seen in the S 12 through S 16 variants, typically reflects a consistent engine displacement and cooling circuit design with little variation between individual units of the same specification.
  • The 9 to 11-liter range listed for the S 18 and S 21 indicates a variable fill capacity. Cooling system fills can vary within a stated range due to factors such as air pockets during draining, the presence of auxiliary heater circuits, or differences in body configurations that affect coolant circuit length.
  • All six variants share a 12-month check interval under normal use conditions. A 12-month coolant check interval is standard practice for monitoring coolant concentration, pH level, and inhibitor strength, none of which are visible without testing.
  • The S 16 appears in two separate entries: one without a displacement designation and one identified as the S 16 3.0. Both carry the same 9-liter capacity and 12-month check interval, suggesting the 3.0-liter engine variant does not alter the cooling system volume relative to the base S 16.
  • The power output designations in the Daily 38 naming convention, such as S 12, S 18, and S 21, correspond to approximate power outputs in tens of kilowatts. The step from S 16 to S 18 coincides with the shift from a fixed 9-liter capacity to the broader 9 to 11-liter range, reflecting the greater thermal load management requirements of higher-output engines.
