CSF Aluminum Radiator, 2014-2019 Fiesta ST

One of the biggest advantages of the CSF Radiator over the OE Unit is the Triple Pass design. The internal routing of the radiator forces the coolant to flow through the core three times (see diagram below), maximizing heat dissipation and resulting in lower coolant temperatures. This type of configuration ensures more even heat dissipation, reducing hotspots and promoting more consistent cooling.
