Additional Notes

  • The McCormick XTX cooling system capacity is 29 liters across the XTX145, XTX165, XTX185, XTX200, and the Tier 2 XTX185, covering both Tier 2 and Tier 3 engine variants within those models. A 29-liter figure is consistent with large agricultural tractor cooling systems, where high thermal loads from sustained field operation demand substantial coolant volume.
  • The XTX215 Tier 2 (2005-2009) carries a notably smaller cooling system capacity of 21 liters, which is 8 liters less than the other XTX variants listed. Despite the XTX215 being the highest-output model in the Tier 2 lineup, the reduced capacity reflects differences in engine architecture or cooling circuit design rather than a direct relationship between power output and coolant volume.
  • All six configurations share an identical change interval of 2000 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger format, combining an operational hour threshold with a calendar limit, accounts for tractors that accumulate hours slowly and would otherwise leave coolant in service beyond its effective service life based on time-related degradation alone.
  • The 10-hour check interval applies uniformly across all XTX configurations listed. In agricultural equipment, a 10-hour check cycle aligns with daily or near-daily inspection routines, allowing operators to monitor coolant level and condition without committing to a full fluid service at that frequency.
  • The Tier 2 and Tier 3 designations refer to emissions standards established by regulatory bodies for off-road diesel engines. The XTX185 appears in both Tier 2 (2005-2009) and Tier 3 (2009-2013) forms, and both share the same 29-liter cooling system capacity and identical service intervals, indicating no change to the cooling circuit specification between emission tiers for that model.
  • The Tier 3 variants, covering the XTX145, XTX165, and XTX185 from 2009-2013, all carry the same 29-liter capacity and 2000-hour/24-month change interval. Tier 3 engines typically incorporate exhaust gas recirculation or other thermal management features that can increase heat rejection demands, making the cooling system capacity a relevant factor in long-term engine reliability under sustained load.
