II. Installation Location and Core Functions
Installation Point: Front wheel system of the engine, directly driven by the fan belt, connected in series with the water tank and engine block water passages, the core component of the entire machine's cooling system.

Core Functions: Forced circulation of antifreeze removes heat from engine combustion, stabilizes operating water temperature, and prevents cylinder scoring and cylinder head deformation; Works with the radiator and intercooler to control intake air and oil temperatures, ensuring power output under heavy loads; Integrated sealing water seal prevents antifreeze leakage and contamination of belts and surrounding components.
