About Us

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. That’s 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 for the antique auto enthusiasts, 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.

We use a combination of the latest brazing technology and TIG welding in our manufacturing process to ensure that the products you receive from us are of the highest quality. Our products include a full line of all aluminum charge air coolers and radiators for class 7 and 8 diesel trucks, a full line of all aluminum and copper/brass radiators for classic vehicles, and a full line of all aluminum industrial and hydraulic oil coolers that utilize our Ultimate Duty C-Bar Design.
