Description
The CSF 7237 High-Performance All-Aluminum Radiator is engineered specifically for the MK6 Ford Fiesta ST to eliminate overheating under aggressive driving, racing, and high-boost applications. The factory plastic tank radiator is known to struggle with rising coolant temperatures, especially on tuned or track-driven 1.6L EcoBoost engines. CSF developed this premium cooling upgrade in collaboration with EcoBoost specialists to deliver maximum reliability, thermal efficiency, and long-term durability.
This CSF radiator uses a motorsport-grade triple-pass flow layout that routes coolant through the core three times for superior heat dissipation and dramatically lower outlet temperatures. Its 31mm high-performance core, precision TIG-welded aluminum construction, and advanced B-Tube Technology improve cooling capacity and efficiency by up to 15% compared to conventional radiator designs. Whether you daily drive your Fiesta ST or push it at the track, this radiator delivers consistent cooling performance.
Perfect for stock, tuned, big turbo, or track-prepped builds.
