CSF High-Performance All-Aluminum Radiator - Ford Fiesta ST (2014-2019) - 7237
Eliminate the notorious factory cooling bottlenecks and keep your 1.6L EcoBoost engine running cool under heavy street and track driving with the CSF High-Performance All-Aluminum Radiator (7237). Even in stock form, the Ford Fiesta ST is prone to elevated coolant temperatures and overheating; adding power or driving hard quickly overwhelms the stock plastic-tank single-row radiator. CSF's upgraded all-aluminum solution provides the ultimate thermal protection your hot hatch needs.
Engineered with a robust 31mm 1-row core and CSF's exclusive B-Tube Technology—which increases heat transfer surface area by approximately 15% over standard welded tubes—this radiator maximizes fluid efficiency and heat dissipation. Featuring ultra-efficient 6.5mm multi-louvered fins, 100% TIG-welded all-aluminum construction, and an advanced triple-pass coolant routing design that forces fluid through the core three times, it drastically reduces coolant temperatures and eliminates hotspots. Designed as a true drop-in fit using CNC-machined OE-style brackets, it installs seamlessly without any modifications.
