21T-03-32430 Coolant Hose supports PC2000-8 engine cooling service for B2B excavator parts replacement, inventory stocking, and wholesale sourcing.
The 21T-03-32430 Coolant Hose YNF18948 is supplied for compatible PC2000-8 excavator engine cooling-system applications. It is used to transfer engine coolant between corresponding cooling components so coolant circulation can be maintained during machine operation.
Cooling hoses on large excavators are continuously exposed to engine-compartment heat, vibration, coolant contact, pressure changes, and long operating cycles. With extended service, cracking, swelling, hardening, surface deterioration, or weakened connection areas may develop and replacement can become necessary.
For B2B buyers, the 21T-03-32430 PC2000-8 water hose should be verified by part number, exact installation position, hose routing, overall length, connection diameters, bend configuration, and existing-part photos. The supplied product information does not specify whether this hose is positioned at the upper, lower, bypass, or another cooling connection. Accurate physical confirmation is therefore recommended before bulk purchasing to reduce incorrect inventory, installation delays, customer claims, and repeat freight.

Q: Which machine is referenced?
A: The supplied machine reference is PC2000-8.
Q: Is this specifically an upper or lower radiator hose?
A: The supplied information only identifies it as a water hose, so the exact cooling-system position should be confirmed.
Q: What should be checked before ordering?
A: Part number, installation position, routing, bends, end diameters, dimensions, and existing-part photos should be verified.
YNF Machinery supplies 21T-03-32430 coolant hoses and related PC2000-8 cooling-system parts for mining-equipment workshops, fleet maintenance businesses, machinery dealers, wholesalers, and international importers.
The YNF18948 water hose is a fitment-sensitive cooling component. For professional B2B buyers, the part number should be checked together with the exact installation position, hose routing, connection diameters, bend configuration, and overall dimensions before quantity purchasing.
Buyers can provide the 21T-03-32430 reference number, PC2000-8 machine information, required quantity, hose measurements, installation-location photos, and clear images of the removed hose for fitment confirmation.
Radiator hoses, radiators, coolant tanks, water pumps, thermostats, radiator caps, cooling fans, and other PC2000-8 cooling-system components can also be consolidated into the same inquiry, helping buyers simplify procurement and reduce fragmented international shipment costs.
