Additional Notes
- The McCormick A-MAX cooling system capacity is 19 liters across the A75 MAX, A80 MAX, and A90 MAX configurations, reflecting a full system fill that includes the engine block, radiator, and associated passages rather than a partial top-up volume.
- The A75 MAX pairs a Perkins 1104C-44 engine rated to Tier 2 emissions standards, while the A80 MAX and A90 MAX both use Perkins 1104D-44 variants rated to Tier 3, yet all three share an identical 19-liter cooling system capacity.
- The A90 MAX uses a turbocharged version of the 1104D-44, designated 1104D-44T, which adds forced induction relative to the naturally aspirated A80 MAX, though the cooling system capacity remains at 19 liters in both cases.
- The coolant change interval for all three configurations is 2000 hours or 24 months under normal use conditions, meaning whichever threshold is reached first would govern the service timing in practice.
- A 2000-hour interval is a relatively extended service cycle by agricultural equipment standards, consistent with the use of long-life coolant formulations designed to maintain corrosion inhibitor effectiveness over prolonged periods.
- The 2016-2021 model years covered by all three configurations share uniform coolant service intervals, indicating no revision to the maintenance schedule occurred across the production span represented in the specifications.
