Product Description
The 190-5841 upper radiator hose (also referenced as 1905841, CA1905841, or upper water hose) is a molded cooling system hose designed for Caterpillar 308C and 308C CR hydraulic excavators. Installed in the upper section of the radiator circuit, it connects the engine coolant outlet to the upper radiator tank to route heated coolant from the Mitsubishi 4M40 diesel engine for cooling.
Molded to match the tight engine compartment routing of compact radius (CR) excavators, this replacement hose is manufactured from heat-resistant synthetic EPDM rubber. It provides reliable resistance against thermal cycling, engine vibration, and antifreeze degradation during continuous excavation operations.
