CAT345D2 Upper Radiator Hose Description
YNF16812 radiator hose is engineered as a direct-fit replacement for Caterpillar part 487-7301, designed for the CAT345D2 excavator. This upper coolant hose connects the engine cylinder head to the radiator top inlet, transporting high-temperature coolant for effective thermal regulation. Built from durable EPDM rubber and reinforced with textile fibers, it resists cracking, softening, and fatigue caused by heat, pressure, and vibration. Its OEM-style curvature ensures proper fitment and minimal stress during installation, helping to prevent coolant leaks and overheating in demanding jobsite conditions.
