Product Description
The Focus ST 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.
CSF has over 5 decades of experience in manufacturing radiators. So when it comes to keeping your engine cool and your Focus ST running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high-horsepower builds as well as race vehicles, which need added cooling performance in motorsports environments. This radiator features a 1-row, 31mm core with CSF's exclusive B-Tube Technology: Unlike a regular oval-shaped "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B." These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal ""O"-shaped tubes that are welded. The design (inlet in the middle of the seam-brazed tube) increases the surface area for heat transfer by approximately 15% over regular tubes—producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow." CSF also uses ultra-efficient multi-louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application and tested for maximum heat rejection efficiency in our wind tunnel lab.
The CSF Focus ST radiator is a true "drop-in fit" design requiring no modifications to install. OE-style brackets are all CNC machined and welded for the best durability possible. Inlet/outlet connections are designed to match the OE connections so you can reuse OEM hoses or aftermarket ones. Trust the cooling experts at CSF for the best-performing, highest-quality, and most reliable radiators.
Design & Engineering
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. This is especially true for those running higher-power racing engines. CSF engineered the radiator for the best possible performance and fitment. These popular systems are now available through CSF's worldwide dealer and distributor network.
While CSF designed the radiator 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.
CSF vs OEM
The original OE radiator from Ford is a plastic tank with a single-row aluminum core design. While this design is pretty standard and works fine for the average customer, it is not the best option for high horsepower builds or hard driving. Furthermore, 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 RS cool for a long time.
The triple-pass design is one of the biggest advantages of the CSF Radiator over the OE unit. 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.
Note: Image is a representation of the quality and design of the CSF radiator. Your application will look different due to your OEM radiator style.
