Koyorad offers our experience of 56 years in the heat exchange industry and is renowned for manufacturing products of highest quality, performance, and fit-and-finish. Koyorad has earned this exceptional reputation through our company’s strict quality control measures. Initially, Koyorad was the leading manufacturer of OE Aftermarket radiators in Japan. After over 10 years in the US, we now offer the same level of quality for US and Europe markets. Koyo radiators are manufactured to the stringent quality and performance tests required by the OE’s, holding Koyo to a much higher standard. This makes Koyo the obvious choice for your vehicle for the best reliability.
Where are Koyorad radiators manufactured? Koyo manufactures four different types of radiators:
OE Aftermarket Plastic Tanks/Aluminum Cores (most common) Design: Japan and China Manufacturing: Indonesia and China
OE Aftermarket All Aluminum (Toyota Sienna, Lexus RX, etc) Design: Japan Manufactured: Indonesia or China
OE Aftermarket Copper / Brass (select vehicles) Design: Japan Manufacturing: Indonesia
Racing All Aluminum Radiators (select performance vehicles) Design: Japan and Indonesia Manufacturing: Japan and Indonesia
Koyo’s R&D departments complete engineering diagrams for each new application. These engineering drawings are then sent to our privately owned ISO-9001 certified factories. Each Koyo radiator is leak tested a total of three times at different stages of the production process before a final visual inspection. Our attention to detail extends further to our rigid boxes, inlet/outlet/corner protection, assuring Koyorad product arrives safely to the end user. Additionally, Koyo conducts “Koyo Training Exchange” programs between our Japan, Indonesia, and China plants from 3 months to a year in the study of Japanese workmanship. This program further ensures the delivery of exceptional Japanese quality to the end user.
Koyorad actually owns its factories? How does this benefit me? Koyo Japan maintains strict control over both R&D and production practices from raw material selection to the end product. We have NEVER outsourced our radiator production to any other manufacturers.
