CSF Ford Fiesta ST 2014-2019 High-Performance Radiator

The 1.6L EcoBoost engine could make impressive power for its size, which made the Fiesta ST a genuine blast to drive, but the factory cooling system was always a known weak point, with overheating issues reported even on completely stock cars. The original OE radiator uses a plastic tank with a single-row aluminium core, which has always been inadequate for anyone driving their Fiesta ST hard, and even just commuting in hot weather can cause overheating. Turbo cars run hot, and the 1.6L EcoBoost is no exception.

CSF's 2-row, 42mm aluminium core is a substantial improvement over the factory core, the combination of a thicker core, second cooling row, and increased fluid capacity drastically improves the amount of heat the system can absorb and dissipate. CSF's exclusive B-Tube technology, a specially engineered "B"-shaped tube carefully formed and brazed over the seam, increases heat transfer by approximately 15% over regular oval welded tubes. This radiator also features a genuine triple-pass flow configuration, allowing coolant to flow across the core three times before exiting for the lowest possible outlet temperatures, rather than the OEM's single pass. 6.5mm tall, super-efficient multi-louvered fins maximise airflow through the core, and 100% TIG-welded, all-aluminium construction increases overall strength and durability considerably over the factory design. All original mounting brackets are CNC machined, allowing the original fan assembly to bolt on without hassle for a complete drop-in fit requiring no modifications.

Works with: OEM mounting points and fan assembly. True drop-in fit.
