Верхний шланг радиатора, внутренний диаметр 56,2 мм Caterpillar 4189977

The Radiator Upper Hose channels heated coolant from the engine coolant outlet toward the radiator inlet to initiate heat dissipation. During combustion cycles, coolant absorbs thermal energy from engine components and flows through this hose to reach the radiator core. The hose enables continuous transfer of high temperature coolant so that thermal energy can be released through the radiator cooling process. It accommodates pressure variation created by coolant circulation and supports uninterrupted flow between connected cooling components.Attributes:• Accommodates pressure variation generated during circulation.• Maintains uninterrupted coolant flow between connected components.• It has a flow rate of 4.5 meters per second.• Capable of withstanding a minimum of 17.3 kilopascal vacuum at 100 degrees Celsius.Applications: The Radiator Upper Hose transfers heated coolant from the engine outlet to the radiator inlet to enable heat dissipation and maintain controlled operating temperature during engine operation cycles.
