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 Koyo company has 12 locations internationally and a group of skilled engineers having over 54 years of valuable experience. They provide the most reliable radiators and condensers on the market. Each Koyo radiator is made in the privately owned ISO-9001 certified facilities, and thanks to the Koyo Training Exchange programs between their Japanese and Indonesian plants, the company is able to deliver exceptional products that are sure to last.

Quick, original, dynamic and innovative, Koyo strives to satisfy every need of every customer and deliver products that will deliver result no matter what. 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.
