The YNF04326 & YNF04327 Radiator Hose Set is a complete coolant hose solution designed for Caterpillar E320D EFI excavators. This set includes the upper radiator hose (265-3602) and the lower radiator hose (245-9178), ensuring full coolant circulation between the engine and radiator.
Manufactured from high-quality reinforced rubber, both hoses offer excellent resistance to high temperature, pressure, coolant chemicals, oil, and engine vibration. The reinforced structure prevents deformation, cracking, and collapse under heavy-duty operating conditions.
Produced according to OEM specifications, this radiator hose set provides accurate fitment and fast installation without modification. It is an ideal aftermarket replacement for preventive maintenance, cooling system repair, and engine overhaul, helping extend engine life and reduce downtime.
