Koyorad has experience of over 60 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 their 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, they now offer the same level of quality for US, Europe & Australian markets.

Koyorad radiators are manufactured to the stringent quality and performance tests required by the OE’s, holding Koyorad to a much higher standard.

Koyorad's R&D departments complete engineering diagrams for each new application. These engineering drawings are then sent to their privately owned ISO-9001 certified factories. Each Koyorad radiator is leak tested a total of three times at different stages of the production process before a final visual inspection.

Koyorad's attention to detail extends further to their rigid boxes, inlet/outlet/corner protection, assuring Koyorad product arrives safely to the end user. This program further ensures the delivery of exceptional Japanese quality to the end user.

This makes Koyorad the obvious choice for your vehicle for the best reliability.
