The Hottest Name in Heat Transfer®


Trace our lineage back far enough and you will find the G&O Manufacturing Company. Opened in 1915, G&O initially supplied Model T owners with quality aftermarket cooling options before expanding their offerings to include aircraft, machinery, and experimental automobiles. Thermal Solutions Manufacturing is proud to carry the same theme of innovation into the modern age.


Thermal Solutions Manufacturing is one of the leading suppliers of heat exchange and diesel emissions products to the heavy duty and industrial aftermarket. With over 20 branches, two distribution centers, and six manufacturing facilities in North America, our footprint is wide and continuously growing. This means personalized service no matter where business happens.


From small family-owned shops to national parts chains, we are here to help the companies that keep your heavy duty and industrial machines running. We bring quality products to the markets we currently serve while continuously anticipating the needs of tomorrow. If there is a product line you think we should carry, let us know!


Our competitive advantage stems from two key elements: Capabilities and Customer Service. We build many of our part numbers in house. Not only can a Thermal Solutions Manufacturing plant build a custom radiator core, we can back it up with experienced customer service representatives that know every step of the manufacturing process.
