Radiator 17118672012 For BMW F10 F11 F18 Engine N20 17118658301 17117626560

NIBD radiator  aluminum tube   is a composite material with a three-layer structure.

Among them, 7072 is aviation-grade anti-corrosion material.Can effectively resist acid rain, atmospheric and other corrosion,Improve product service life.

We control the radiator fins  at the best window opening angle of 28° (±2°),  can disturb the airflow attached to the fins effectively.I mprove the efficiency of heat exchange on the fin contact surface.

The radiator is composed of hollow copper tubes. High temperature water into the water tank through the air cooling and circulation to the engine cylinder wall to protect the engine, if the winter water temperature is too low, this time will stop the water circulation, to avoid the engine temperature is too low. 

‌ The role of the car water tank is to dissipate heat to ensure that the engine can be maintained within the normal temperature range at all speeds or driving conditions.
