This U.S. Radiator (right) features the company’s high-efficiency core, which uses 1/2-inch tubes on 3⁄8-inch centers, compared to most old brass and copper radiators which had the tubes mounted on 9⁄16-inch centers. This means more tubes and more contact with cooling fins for better heat transfer.
