So ya the Neukin Civic Radiator and Fan was good before but after some thought they made it better. The old design used a aluminum stud and nut with some red loctite for those no worry moments. The New design from Neukin features a cool and yet simple aluminum stud and pin. The four mount points on the radiator bracket that hold the fan are all using this new design. This allows tooless removal and no loctite. Given you wont have to remove your fan often its just another cool feature of the never ending “make things better” mind set the guys at Neukin have.
