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.

The manufacturer employs only 'made in Japan' machinery and uses only high-grade materials when crafting their radiators and condensers. Koyo quality begins with their wide selection of premium OE-grade materials, such as aluminum, brass, copper, and plastics. All Koyo products are designed and developed to withstand harsh elements as well as provide years of under-hood heat cycling.

    What sets Koyo apart from its competitors is the ability to react quickly to market changes. Their Engineering Department continuously strives to upgrade every existing Koyorad radiator and create solutions for emerging vehicles. The company's experts find ways to implement new technologies in their products; however, before any new model is released, Koyo engineers extensively test products for fit, finish, and performance. That means customers instantly get products that are second-to-none in terms of engineering excellence and reliability.

    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.
