193-2785 Upper Radiator Hose for Caterpillar 330C E330C

193-2785 Upper Radiator Hose for Caterpillar 330C E330C

The 193-2785 upper radiator hose (also referenced as 1932785 or upper water hose) is a molded cooling system hose designed for Caterpillar 330C series excavators, commonly referred to in the aftermarket as E330C. Installed in the upper section of the radiator circuit, it connects the top radiator port to the engine coolant outlet housing to carry heated coolant from the Caterpillar C-9 engine to the radiator for heat dissipation.

Manufactured to match original routing geometry with a 50 mm (1.97 in) inner diameter, this replacement hose is constructed from heat- and chemical-resistant EPDM rubber to withstand continuous cooling system pressure, engine vibration, and exposure to antifreeze chemicals.
