The CSF teamed up with industry EcoBoost experts to bring you the best radiator upgrade for the Focus ST. They needed a solution to the excessive coolant temperatures many of their customers were seeing. Especially those running their higher power racing engines. CSF engineered the radiator for the best possible performance and fitment. These popular systems are now available through CSF's world wide Dealer and Distributor network.
While the radiator was designed for super high performance race engines, anyone with a Focus ST can benefit from upgrading. Even modest power increases and hard driving can put a strain on the factory cooling system. The CSF Radiator is the ultimate cooling solution for any Focus ST owner.
The original OE radiator from Ford is a plastic tank with a single row aluminum core design. While this is pretty standard and works fine for the average customer, it is not the best option for high horsepower builds or hard driving. Also, Turbo cars get hot, and the 2.0L EcoBoost is no exception. Anything you can do to help keep coolant temps in check will improve the longevity of your engine and help the car run smoothly.
The CSF 31mm aluminum core is a big improvement over the factory core. A thicker core and increased fluid capacity drastically improves the amount of heat the system can absorb and dissipate. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible cooling performance.
The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident the CSF radiator will keep your Focus ST cool for a long time.
One of the biggest advantages of the CSF Radiator over the OE Unit is the Triple Pass design. The internal routing of the radiator forces the coolant to flow through the core three times (see diagram below), maximizing heat dissipation and resulting in lower coolant temperatures. This type of configuration ensures more even heat dissipation, reducing hotspots and promoting more consistent cooling.
