CSF 7239 Aluminum Radiator – Fits Ford Focus RS 2016-2018

The CSF #7239 aluminum radiator offers a significant upgrade over stock cooling components for Ford Focus RS models from 2016 to 2018. Featuring a 42mm 2-row aluminum core, this radiator provides increased fluid capacity and improved heat dissipation, essential for high-performance driving or hot climates. The core\'s design includes a third-pass flow configuration, which allows coolant to flow across the core three times before exiting, resulting in lower outlet temperatures and enhanced cooling efficiency. Additionally, the multi-louvered fin design maximizes airflow through the core, further aiding in heat transfer and maintaining optimal engine temperatures.
Constructed with 100% TIG-welded aluminum and incorporating CSF\'s exclusive B-Tube technology, this radiator ensures superior heat transfer performance—approximately 15% more effective than conventional oval welded tubes. The product is designed as a
