Reform Metrac

Additional Notes

• The Reform Metrac 2003 (1989-2000) carries the smallest cooling system capacity in the lineup at 4.8 liters, roughly half the volume of the Metrac 3003 variants produced during the same period. A lower coolant capacity generally reflects a smaller engine displacement and reduced thermal load.
• The Metrac 3003, S, and K share an 8.7-liter cooling system capacity across the 1989-2000 production span. The shared figure across three distinct variants — standard, S, and K — indicates a common engine cooling architecture despite any differences in trim or configuration.
• Both the Metrac 4004 and 4004 H, produced from 1992-2000, specify an identical 9-liter cooling system capacity. The matching value between the standard and H variants suggests the hydraulic or mechanical differences between the two did not require a change in engine cooling volume.
• All 1989-2000 models — the 2003, 3003 series, 4004, and 4004 H — share a coolant change interval of 24 months with no hour-based threshold. A time-only interval is common when operating hours are variable or low, making calendar-based degradation the more reliable trigger for coolant replacement.
• The Metrac H6 X and H7 X (2011-2013) both specify a 9.5-liter cooling system capacity. Despite carrying different model designations that typically indicate differing power outputs, the identical coolant volume points to a shared engine cooling circuit design.
• Starting with the 2011-2013 H6 X and H7 X models, the coolant change interval shifts to a dual threshold of 600 hours or 24 months, whichever comes first. The addition of an hour-based limit alongside the calendar interval reflects the higher or more consistent operational demands expected of these machines compared to the earlier 1989-2000 models.
• The Metrac H7 X with engine code 39D/1 (2016-2022) specifies a 13.2-liter cooling system capacity, a notable increase from the 9.5 liters of the earlier H7 X (2011-2013). The larger volume corresponds to a different engine variant, as indicated by the engine code designation, and a greater coolant capacity generally supports higher thermal output or a more complex cooling circuit.
• The Metrac H8 X with engine code 34D/7 (2016-2022) shares the 13.2-liter cooling system capacity of the 2016-2022 H7 X 39D/1. Both models also share the 600-hour or 24-month change interval, indicating a common service schedule despite carrying different engine codes and model designations.
• Across all eight configurations, the coolant level check interval is uniformly set at 10 hours. A 10-hour check frequency is a short cycle consistent with the operating conditions of alpine or slope-work machinery, where coolant loss through minor leaks or system stress could have more immediate consequences than in standard agricultural equipment.
