As the fan spins, each blade draws air through the cooling stack, helping regulate engine operating temperature. This airflow pattern changes naturally with engine speed, increasing cooling output at higher loads. The blade mounts directly to the fan hub and rotates continuously while the engine runs. Its multi-blade design distributes airflow evenly across the radiator surface. The PAI 450464 contributes to thermal regulation during engine operation.
