What started as a local radiator service shop in 1956 has expanded to become one of the industry leading manufacturers of high quality all aluminum charge air coolers, oil coolers, and radiators for both industrial and automotive needs. Because of our roots in servicing radiators and automobiles, we recognized the need for high quality products that are built to last. Thats why we started manufacturing our own radiators, oil coolers, and charge air coolers here in the U.S.A. in 2004. Recently we expanded our manufacturing capabilities to include copper/brass radiators, and we continue to refine and improve our build processes to ensure you receive the best quality all aluminum and copper/brass products. Building everything in house allows us to also provide custom manufacturing services. You can work directly with our engineers to ensure you get the exact product you need for your custom automotive build or unique industrial application. With our years of experience and thousands of units in service in North America and globally, you can have confidence that C, G, & J Inc. can handle all your industrial and automotive cooling needs.
