01497952 Coolant Expansion Tank features a 2-hole configuration for B2B excavator parts repair, cooling maintenance, and wholesale sourcing.
The 01497952 Coolant Expansion Tank YNF17656 is supplied as an auxiliary reservoir for compatible engine cooling systems, with 2039948 provided as an additional reference. The product is identified by its 2-hole configuration, which should be compared carefully with the existing tank before replacement.
During engine operation, coolant volume changes as temperature rises and falls. The auxiliary tank provides additional coolant capacity and forms part of the cooling-system overflow or recovery arrangement according to the machine configuration.
For B2B buyers, the YNF17656 coolant sub tank should be checked by both reference numbers, tank shape, 2-hole layout, hose or connection positions, mounting points, cap configuration, and existing-part photos. Accurate identification helps wholesalers and repair workshops reduce installation mismatch, customer returns, and unnecessary international freight.

The YNF17656 sub tank is identified as a 2-hole version, making configuration confirmation especially important before purchasing. Similar coolant reservoirs can differ in mounting positions, connection layout, tank shape, and cap design even when their general appearance is close.
Professional buyers can provide both reference numbers, required quantity, tank dimensions, 2-hole layout, hose or connection positions, mounting details, and clear photos of the existing reservoir for confirmation.
Radiators, radiator caps, coolant hoses, thermostats, water pumps, cooling fans, and other cooling-system components can also be included in the same inquiry.
