193-2786 Lower Radiator Hose for Caterpillar 330C E330C

193-2786 Lower Radiator Hose for Caterpillar 330C E330C

The 193-2786 lower radiator hose (also referenced as 1932786 or lower water hose) is a molded replacement coolant hose for Caterpillar 330C series excavators, commonly known in the aftermarket as E330C. Positioned at the bottom of the radiator assembly, it connects the lower radiator outlet to the engine water pump inlet to return cooled fluid back into the Caterpillar C-9 engine block.

Built with a 49 mm (1.93 in) inner diameter to match original equipment routing, this hose is molded from reinforced, heat-resistant EPDM rubber. Its multi-ply construction helps resist suction collapse under high water pump draw while withstanding engine heat, vibration, and antifreeze corrosion.
