CAT303.5E Radiator Lower Hose Description
The YNF18667 Radiator Lower Hose is an aftermarket cooling system replacement component designed for CAT303.5E excavator applications. With OEM reference number 010541, this lower radiator hose is used to support stable coolant circulation between the radiator and engine cooling system.
Manufactured from durable heat-resistant rubber, the CAT303.5E radiator lower hose is designed to withstand high temperatures, continuous coolant contact, and vibration generated during excavator operation. The flexible structure helps maintain reliable sealing performance and supports efficient engine temperature control.
The radiator lower hose is an essential part of the excavator cooling system because it helps complete the coolant circulation process. When the hose becomes cracked, hardened, or damaged after long-term operation, coolant leakage and engine overheating risks may increase.
The YNF18667 excavator radiator hose is suitable for construction equipment dealers, repair companies, and spare parts wholesalers. By providing accurate replacement components, YNF helps customers improve maintenance efficiency, reduce machine downtime, and maintain reliable inventory supply.
