The YNF16760 & YNF16761 Radiator Hose Set is designed for E329D2 excavators, including both the upper and lower hoses in the engine cooling system. The upper hose transfers hot coolant from the engine to the radiator, while the lower hose channels cooled coolant back to the engine. Together, they ensure efficient heat exchange, stable engine operating temperatures, and protection against overheating during continuous or heavy-duty operation.
