Description CSF 7238 High-Performance All-Aluminum Radiator for FORD Focus ST (MK3) 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. - 1-Row – 31mm Ultra-High-Performance Core - Triple Pass Flow Configuration Allows Coolant to Flow Across the Core Three Times Before Exiting for Lowest Outlet Temperatures Possible - Cooling Tubes with CSF’s Exclusive B-Tube Technology - 6.5mm Tall Ultra Efficient Fins with a Multi-Louvered Design for Maximum Surface Area Contact - CNC Machined Mounting Pins and Brackets - OEM Style Inlet/Outlet - 100% All Aluminum TIG-Welded Construction - True Plug-and-Play “Drop-in Fit” Installation Requires Absolutely No Modifications - Individually Leak and Pressure Tested - 2-Year Limited Warranty
