68-70 Ford Mustang Cougar Copper Big Block radiator 24" wide with High Efficiency core

This radiator was manufactured by US Radiator. It is a high efficiency three row core. This means that the tubes and fins are closer together than a standard core creating a denser and more efficient core. It will cool the same as a conventional four row core without the added core thickness that may cause interference with the fan blade in some applications. Even the largest radiator cannot cool properly without good airflow. Consider replacing your stock 5 blade fan with a six or seven blade fan for optimum cooling. 100% Made in USA. Beware of less expensive radiators manufactured by companies you never heard of. 1 Year Guarantee.
