Koyorad

Founded in July 1956 as Ejiri Radiator in Nagoya, Japan (Aichi Prefecture), Koyorad started as a radiator repair shop. By 1968, the company expanded to include a dedicated radiator and oil cooler factory in Nagoya, separating production from repair operations. In 1970, Ejiri Radiator evolved into Koyo Radiator Manufacturing and began opening branches throughout Japan. This marked the start of its transformation into a global leader in the aftermarket radiator industry as Koyorad.
