Additional Notes

  • The Iveco Daily 55 cooling system capacities across the listed configurations fall into two distinct groups: 9 liters and 16 liters. The 9-liter figure appears across all 4x4 variants, while the 16-liter figure is associated with non-4x4 configurations such as the 55 S 15 Euro 3 and 55 S 17 H Euro 6.
  • A 16-liter cooling system capacity is notably large for a light commercial vehicle and reflects a higher-volume engine cooling circuit, typically associated with larger displacement diesel engines requiring greater thermal management.
  • The 9-liter capacity on 4x4 variants such as the 55 S 18 (4x4) and the 55 C 18H-WX (4x4) Euro VI E suggests a more compact cooling circuit, which is common in configurations where drivetrain packaging constraints influence the cooling system layout.
  • The 55 S 15 Euro 3 carries both a 12-month check interval and a 36-month change interval under normal use conditions. The separation of check and change intervals means coolant condition is monitored annually while full replacement occurs on a longer three-year cycle.
  • The 55 C 18H-WX (4x4) Euro VI E stands apart from the other listed configurations by specifying a 24-month check interval rather than the 12-month interval seen across the remaining rows. A longer check interval on a Euro VI engine may reflect the use of modern long-life coolant formulations with extended service stability.
  • The 55 S 17 H Euro 6 (2014-2016) and the 55 S 18 (4x4) across its 2016-2018, 2018-2021, and 2021 onward variants all share a 12-month check interval under normal use, with no change interval specified in the listed data.
  • The 55 S 18 (4x4) configuration spans three separate year-range entries from 2016 onward, each carrying identical specifications of a 9-liter capacity and a 12-month check interval, indicating consistent cooling system requirements across those production periods.
  • Coolant check intervals measured in months rather than mileage are standard practice for cooling systems, as coolant degradation is driven primarily by time and thermal cycling rather than distance traveled.
