John Deere T series
Coolant capacity & service interval
John Deere T series coolant capacity ranges from 40 to 45 liters. Service intervals include checking every 10 hours and changing every 2000 hours or 24 months. The data covers 8 configurations.

Additional Notes
- All John Deere T Series cooling system capacities listed are service fill figures, meaning the volume required when refilling a drained system during routine maintenance rather than a full overhaul capacity that would account for additional fluid retained in components such as the engine block.
- The listed capacity values carry a "(+ heater)" notation, indicating the figures do not include the volume held within the cab heater circuit. When a heater core and its associated plumbing are present, the total system volume will exceed the stated capacity.
- Across the T550 and T560 Tier 2/Stage II variants covering 2009-2014, the cooling system capacity is rated at 40 liters. The T560 Tier 4/Stage IV (2015-2019) carries a higher capacity of 45 liters, reflecting the additional cooling demands associated with Tier 4/Stage IV emissions hardware such as exhaust aftertreatment components.
- The T660 and T670 follow the same capacity pattern as the T560: Tier 2/Stage II configurations from 2009-2014 are rated at 40 liters, while Tier 4/Stage IV configurations from 2015-2019 are rated at 45 liters.
- The T550 is the only model where both the Tier 2/Stage II and Tier 4/Stage IV configurations share an identical 40-liter cooling system capacity, with no increase seen in the later emission-tier variant.
- A 10-hour check interval applies uniformly across all T Series configurations listed. In machine operating contexts, 10 hours corresponds roughly to a single working day, making the coolant level check a daily pre-operation or post-operation task.
- The coolant change interval is specified as 2000 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger format means that calendar time governs the change schedule on machines with lower annual utilization, while operating hours govern it on machines used more intensively.
- The 2000-hour/24-month change interval is consistent across all eight configurations listed, spanning both Tier 2/Stage II and Tier 4/Stage IV emission standards and all four model designations (T550, T560, T660, T670).
