Internal Combustion Engine Cooling

Our long-established Internal Combustion Engine Cooling Systems has been at the forefront of Grayson Thermal Systems through our growth in the 1990s and are still an important product line today.

Over the decades of manufacturing these cooling modules, we have refined the development to ensure guaranteed durability. Our systems use tube technology to deliver ultimate reliability whilst also giving peak thermal performance via our high-performance louvered fin or dimpled fin, depending on the operational requirements of the application and the installation location on the vehicle.

When you work with us, we also conduct our own precise thermal calculations and application study with you. This enables us to review and recommend the best solution for your application, giving you complete peace of mind once the vehicle is delivered to the marketplace.
