Additional Notes
- The Komatsu WF450-3 and WF450T-3 share an identical cooling system capacity of 68 liters, indicating a common engine cooling architecture between the standard and T-suffix variants in the 450 series.
- The WF550-3 and WF550T-3 each carry a cooling system capacity of 88 liters, reflecting the larger engine displacement and greater thermal load management requirements of the 550 series relative to the 450 series.
- The 20-liter difference in coolant capacity between the 450 and 550 series models represents a significant step up in cooling system volume, consistent with the increased power output and heat rejection demands of a larger compactor platform.
- All four models across the 2000-2003 production span are rated under normal use conditions, meaning the 68-liter and 88-liter capacities apply to standard operating environments rather than severe-duty cycles.
- Cooling system capacity figures of this magnitude, ranging from 68 to 88 liters, are characteristic of total system fills that include the engine block, cylinder head passages, radiator, and associated hoses and reservoirs, rather than a partial drain-and-refill service quantity.
- The T-suffix designation on the WF450T-3 and WF550T-3 does not alter the cooling system capacity relative to the non-T counterparts, as both pairs share identical coolant volumes within their respective series.
