3TNA72 Radiator Fan provides cooling airflow for compact machinery maintenance, B2B excavator parts sourcing, and engine repair applications.
The 3TNA72 Radiator Fan YNF18690 is supplied for compatible diesel engine cooling-system applications. When the engine is running, the fan is rotated to move air through the radiator area, allowing accumulated engine heat to be transferred more efficiently.
This fan is identified by the supplied 318.5-24-41 4T6 specification reference. Because cooling fans with similar appearances may use different hub dimensions, mounting patterns, blade profiles, or orientations, the reference should be compared together with physical measurements rather than being used alone.
For B2B machinery parts buyers, YNF18690 should be confirmed by engine model, fan dimensions, center mounting configuration, blade geometry, and existing-part photos before quantity purchasing. Careful fitment verification helps wholesalers and repair workshops reduce incorrect inventory, unnecessary return freight, and delays during engine cooling-system maintenance.
