CSF High Performance All Aluminium Radiator Ford Focus RS Mk3

The Mk3 Focus RS was very well engineered and performed admirably out of the box. However, a few upgrades can quickly lead to heat issues, especially on the track or in hot climates. An upgraded radiator from CSF is the perfect solution to keeping the coolant temps in check.

Design And Engineering

The CSF teamed up with industry EcoBoost experts to bring you the best radiator upgrade for the Focus RS. 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.

While the radiator was designed for super high performance race engines, anyone with a Focus RS 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 RS owner.

CSF vs OEM

The original OE radiator from Ford is a plastic tank with a single row aluminium 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 2.3L 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 42mm 2-Row aluminium core is a massive improvement over the factory core. 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 maximise airflow through the core for the best possible cooling performance.

The TIG-Welded 100% All Aluminium 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 RS 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, maximising heat dissipation and resulting in lower coolant temperatures. This type of configuration ensures more even heat dissipation, reducing hotspots and promoting more consistent cooling.
