( CSF #7237 )
The MK6 Fiesta ST won over the hearts of many tuners and enthusiasts when it hit the market over 10 years ago. It was the perfect blend of affordable, practical, and tunable. The 5-Door design made it incredibly practical for those looking for one car to “do it all”. You could commute, do a Costco run, and still have it suitable for track days on the weekend.
The 1.6L EcoBoost motor could make some impressive power for the size which made the Fiesta ST a blast to drive. However, the factory cooling system was always a problem with the car having overheating issues even when completely stock. The best solution is a High Performance All-Aluminum Radiator from CSF.
Design & Engineering
The CSF teamed up with industry EcoBoost experts to bring you the best radiator upgrade for the Fiesta 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. This popular system will now be available through CSF’s world wide Dealer and Distributor network.
While the radiator was designed for super high performance race engines, anyone with a Fiesta ST can benefit from upgrading. Even modest power increases or even just hard driving can cause overheating with the factory radiator. The CSF Radiator is the ultimate cooling solution for any Fiesta ST owner.
CSF vs OEM
The original OE radiator from Ford is a plastic tank with a single row aluminum core design. It has always been inadequate for anyone driving their Fiesta ST hard. Even just commuting in really hot weather can cause overheating issues. Turbo cars get hot, and the 1.6L 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.
CSF’s 42mm 2-Row aluminum core is a massive improvement over the factory core. The combination of a thicker core, second cooling row, 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.
All CSF Performance Radiators are 100% TIG-Welded All Aluminum construction which increases the overall strength of the radiator. This improves durability and longevity so you can be confident the CSF radiator will keep your Fiesta ST cool for a long time.

Triple Pass Advantage
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.
