Additional Notes

  • The Case-IH Magnum AFS Connect lineup splits into two distinct cooling system capacity groups. The Magnum 180, 200, 220, and 240 AFS Connect Tier 4b models share a 23.65-liter cooling system capacity, while the Magnum 250, 280, 310, 340, 380, and 400 AFS Connect Tier 4b models use a noticeably larger 42-liter cooling system.
  • The 42-liter capacity of the higher-output models represents a roughly 78 percent increase over the 23.65-liter figure, reflecting the greater thermal load generated by larger displacement or higher-output engines in the upper range of the lineup.
  • The 23.65-liter group carries a coolant check interval of every 10 hours under normal use conditions. No equivalent periodic check interval appears in the specifications for the 42-liter group.
  • Coolant change intervals differ significantly between the two capacity groups. The 23.65-liter models specify a change at 2,100 hours under normal use, while the 42-liter models specify a change at 4,200 hours or 60 months, whichever comes first.
  • The 4,200-hour change interval on the 42-liter group is exactly double the 2,100-hour interval on the 23.65-liter group. Extended-life coolant formulations are commonly associated with intervals in the 4,000-hour or 5-year range, suggesting a different coolant chemistry may be specified for the larger-capacity systems.
  • The 60-month calendar limit paired with the 4,200-hour interval on the larger models means coolant age alone can trigger a change regardless of accumulated machine hours. At typical agricultural usage rates, calendar time may be the governing factor for lower-utilization machines.
  • All ten configurations carry a normal use condition designation, meaning none of the listed intervals are adjusted for severe-duty operation in the specifications provided.
  • All models across both capacity groups are designated Tier 4b, referring to the U.S. EPA Final Tier 4 emissions standard, which requires exhaust aftertreatment systems that can generate additional heat loads and influence cooling system sizing.
