Нижний шланг радиатора, внутренний диаметр 49 мм Caterpillar 6539911

The Lower Radiator Hose carries coolant from the bottom of the radiator back into the engine’s cooling system. It completes the coolant circulation cycle by allowing cooled fluid to re-enter the engine. This hose is to withstand pressure changes, engine vibrations, and temperature fluctuations during continuous operation. It is routed from the lower radiator outlet to the engine’s water pump or coolant inlet port. It helps prevent overheating by ensuring consistent coolant return to avoid kinking.Attributes:• Remains structurally stable under engine vibration and movement.• Helps prevent engine damage due to coolant flow interruption.• Withstands contact with oil, heat, and road debris over time.Applications:The Lower Radiator Hose is located between the bottom outlet of the radiator and the engine’s coolant inlet. It returns cooled fluid from the radiator into the engine for recirculation.
