Koyo Radiator Company, Ltd. was founded in July 1956 as the Ejiri Radiator Industries in Nagoya, Japan. Two years later, the company was renamed to Koyo Radiator Manufacturing and expanded its production. In 1968, Koyo decided to separate service and production facilities, and that's when they established a radiator and oil cooler factory in Nagoya. Now, this company is one of the largest and most trusted manufacturers in the business.

    Koyorad 2375 Radiator
    So far so good. I installed the radiator over two weeks ago. No problems, good fit for my car. It is awkward that the box it came in was labelled with TYC rather Koyorad.
