Where are the heavy duty and standard radiators?
A. Heavy duty and standard are marketing terms that do not mean a whole lot to cooling performance. Radiator buyers might instead ask questions like …what is the tube configuration, how many fins per inch, how is the fin material constructed, what type of solder was used, where is your copper sourced, how deep is this core, what gauge are the size walls and mounting brackets, how thick is the tank material, how do you test your radiators, what size radiator do I need for my application, do you actually make these cores etc. The answers will help you find a qualified radiator manufacturer and the best radiator for your car.
