This is an aftermarket radiator (genuine type) for Honda CB400SF NC31.

Size (approx): same as genuine parts
Material: Aluminum
Color: Black
A radiator plays a role in circulating cooling water inside the water jacket of the engine cylinder, which becomes hot due to the explosion combustion of the mixed gas,
by means of a water pump, and stabilizing the water temperature through airflow and heat dissipation.
It is installed at the front of the engine or below the headlamp where airflow is easy, providing high heat dissipation efficiency.

When continuous low-speed driving, idling, or during hot summer days when outside air temperature is high, cooling performance may not keep up, so

an electric cooling fan is installed behind the radiator to dissipate heat.
If debris from the road surface is kicked up by the vehicle ahead and hits and damages the radiator,

it can cause overheating and damage to the engine if left as is, so replacement is necessary.
Instead of using expensive genuine parts for replacement, you can reduce costs by using reasonably priced aftermarket parts that are equivalent to genuine parts.

Early detection of radiator abnormalities through daily inspections is possible, so if there is a coolant leak or core damage, replacement is recommended.
*Instruction manual is not included.

*Since there may be individual differences depending on the vehicle, some modifications may be required for installation.
*If used on vehicles other than the compatible models, we cannot answer questions, so please understand.

*If you are not confident in installation, it is recommended to have it installed by a professional or a mechanic.

*As an imported product, there may be slight dents, warping of fins, or bending of brackets.

交換も高価な純正部品を使うのではなく、純正部品同等のリーズナブルな社外品を使用することによってコストを抑えることができます。

・ラジエターに異常はないか日常点検により早めに故障を発見できますので、冷却水漏れやコアの破損がありましたら交換をお勧めします。
