ND116140-0050 Heater Core supports cab heating heat exchange for B2B excavator parts repair, HVAC maintenance, and wholesale sourcing.
The ND116140-0050 Heater Core YNF17393 is supplied as a heat-exchange component for compatible excavator and construction machinery cab HVAC systems. Warm engine coolant is circulated through the heater core, while cabin air is passed across the core surface so heat can be transferred into the operator compartment.
The heater core is different from the main engine radiator because its primary function is cab heating rather than engine coolant heat rejection to outside air. If the core becomes blocked, corroded, damaged, or leaking, cabin heating performance may be reduced and coolant leakage may occur inside the HVAC area.
For B2B buyers, the ND116140-0050 cab heater core should be confirmed by reference number, core dimensions, pipe positions, mounting points, and existing-part photos before quantity purchasing. Accurate matching helps reduce installation problems, returns, and unnecessary international freight.

Q: What is the part number?
A: The reference part number is ND116140-0050.
Q: What does a heater core do?
A: Heat from engine coolant is transferred into cabin airflow for operator-compartment heating.
Q: Is a heater core the same as the engine radiator?
A: No. The heater core is used for cab heating, while the main radiator is used for engine cooling.
YNF Machinery supplies ND116140-0050 heater cores and related excavator cab HVAC parts for machinery dealers, repair workshops, wholesalers, and international importers.
The YNF17393 cab heater radiator is intended for compatible heating-system replacement requirements. Because heater cores with similar appearances may differ in core size, pipe direction, tube diameter, and mounting positions, fitment should be checked before ordering.
Professional buyers can provide the ND116140-0050 reference, required quantity, core height and width, pipe positions, mounting details, and clear photos of the existing heater core for confirmation.
Blower motors, evaporators, condensers, heater valves, HVAC hoses, and other excavator cab air-conditioning parts can also be included in the same inquiry to simplify B2B sourcing.
