Proper Radiator Choices and Maintenance - Cool Runnings Photo Gallery
Here’s a shot of the clad aluminum cooling tubes. In the foreground is a typical tube from the Street and Racer Series. In the background is a Cup-style cooling tube that may someday make its way down to the Saturday night levels. Notice the dimples in the tube; they’re designed to help create turbulence in the coolant as it passes by so more of it comes into contact with the walls of the tubing.
