DeWitts aluminum radiators are made in the USA and 100% of the manufacturing process is managed in house. We have the capability to build custom aluminum radiators with a variety of tube widths and fin designs. We have several fin machines to produce the type of fin required for your application. Most of our radiators are assembled with press-formed end tanks. This eliminates the fabrication seams and potential leak points of a common box tank. It also provides an original look for those classic cars. In 2007, we installed a state-of-the-art aluminum brazing line which allows us to produce the finest aluminum cores in the industry. We have the capability to develop, braze, and build all types of aluminum heat exchangers for mobile and industrial applications. In addition to our brazing capabilities, we can complete your component in our fabrication department where we offer both low and high volume aluminum welding services.



Located in Howell, Michigan, our modern facility is the ultimate location for proto-typing and developing your next project.


Our engineering professionals use the most advanced platforms, such as SolidWorks, to design the most innovative products in the industry.


Our robotic welding cell for high volume production features a new Fanuc Robot and CMT technology. We also have water jet, laser cut, CNC brake and other capabilities.


DeWitts produces high quality radiators and cores. These cores are epoxy free and defect free. Each part goes through our stringent quality control process.


With over 88 years of combined experience, the DeWitts staff is ready to help you get the best cooling package implemented for your project.
