The CSF performance radiator for 2014–2019 Ford Fiesta ST replaces the factory unit with a 42mm, 2-row aluminum core and a triple-pass flow design to lower coolant temperatures. CSF’s B-Tube technology boosts heat transfer by roughly 15%, while multi-louvered fins and increased fluid capacity improve dissipation. It’s a drop-in aluminum radiator aimed at resolving overheating under hard driving.
